“They’re Building Houses From Dirt Now”: Japan’s Revolutionary Discovery That Changes Construction Forever
In a groundbreaking move that could redefine sustainable construction, Japanese company Lib Work is utilizing 3D printing technology to build homes using earth instead of traditional concrete, offering a glimpse into the future of eco-friendly architecture.
In recent years, 3D printing has made significant strides in the construction industry, with innovative projects sprouting up around the globe. From rapid construction homes in Portugal to the architectural marvel of the 6,500-square-foot Wavehouse in Germany, the technology is reshaping how we think about building. Now, a Japanese company called Lib Work is pushing the boundaries of sustainability in 3D printing by using earth instead of concrete as a primary building material. Their prototype, the Lib Earth House, stands as a testament to what can be achieved when tradition and technology intersect in novel ways.
Saying Goodbye to Concrete: Embracing Earth
While Lib Work is not the first to explore 3D printing in construction, it distinguishes itself by completely eliminating concrete from its building process. Traditionally, concrete has been a staple in 3D printed structures, especially for foundations. However, Lib Work has opted for a combination of earth, lime, and natural fibers, even for the foundation. This innovative approach has resulted in a single-story home with an area of approximately 1,100 square feet. The company’s decision to forgo concrete is not merely symbolic; they have also developed technology to ensure that their unique material mix possesses adequate strength and workability for construction purposes.
Lib Earth House Model B: Key Features
The creation of the Lib Earth House involved collaboration between Lib Work Co., Arup, and Wasp, the manufacturer of the 3D printer used. The house’s standout feature is its recyclability at the end of its lifecycle. Key elements include:
Component
Description
Foundations and Walls
Earth-based mixture
Structure
Wooden frame
Rooms
Living/dining area, bathroom, kitchen, toilet
Exterior Environment
Court with natural space
Technology
Tesla Powerwall battery + solar panels
Style
Modern
The use of renewable energy sources like solar panels and Tesla’s Powerwall battery further underscores the project’s commitment to sustainability. The modern design is not just an aesthetic choice but a statement about the future of eco-friendly living.
The Future of Construction and Lib Work
3D printing in construction offers numerous advantages, including rapid execution, cost-effectiveness, and efficient material usage. This method significantly reduces environmental impact, whether using concrete or earth. For Lib Work, the ability of 3D technology to create shapes that are otherwise impossible to construct opens doors for extreme customization. This is not limited to residential homes but extends to other types of buildings as well. The company is eyeing future projects that could even involve construction on Mars, illustrating their far-reaching vision.
Challenges and Opportunities in Sustainable Construction
The shift from traditional materials like concrete to more sustainable options such as earth involves several challenges. Ensuring the structural integrity and durability of earth-based materials is a primary concern. However, as technology advances, these challenges are being met with innovative solutions. Lib Work’s approach could inspire other companies to explore similar sustainable practices. The construction industry is at a pivotal point where environmental considerations cannot be ignored. As companies like Lib Work demonstrate the potential of earth-based 3D printing, the industry could see a broader adoption of these methods.
The journey towards sustainable construction is not without its hurdles, but the opportunities for reducing environmental impact and enhancing living conditions are immense.
As we look to the future, the question remains: How will the integration of sustainable materials and advanced technologies shape the next generation of construction practices? The potential for change is significant, and the direction we choose could redefine the built environment for years to come.

The race to build AI infrastructure is on and speed is everything
Amid the challenges now synonymous with building AI infrastructure, stakeholders still expect data centers on demand. So, what are the best strategies for delivering next-gen facilities, fast?
The rapid evolution of AI is reshaping industries and data centers are at the epicenter of that change. AI has transformed how we design, build, and operate these facilities. It is driving demand for new infrastructure centers built to handle high-density workloads, designed with scalability at their core.
This urgency is further compounded by complex supply chain issues, including shortages of critical components, extended lead times, and rising material and transportation costs. At the same time, labor and knowledge gaps, plus mounting demand for power to support energy-hungry applications, present layers of challenges.
In this high-pressure landscape, Exyte supports operators with strategies built for speed, scale, and reliability. As a global leader in end-to-end infrastructure solutions, Exyte draws on deep technical experience, strong vendor relationships, and modular construction expertise.
Axel Favillier, director project & construction management data centers at Exyte, explains how a manufacturing mindset and early engagement are key to staying ahead of supply chain volatility and rising technical demands. Even amid uncertainty, Exyte’s strategy enables clients to move quickly, reduce risk, and compete at scale.
Getting ahead of the supply chain
Volatility in the global supply chain has become a familiar challenge, as geopolitical factors and material shortages regularly disrupt access to essential components and systems. For data centers, these disruptions are threatening project timelines and budgets.
To stay ahead, Exyte prioritizes early and proactive involvement in the procurement process. By engaging at the design stage and promptly securing orders for essential equipment, Exyte can minimize the risk of delays and enhance the resilience of project schedules.
According to Favillier, “This approach keeps projects moving and ensures teams are ready to pivot when challenges arise.” At the same time, the company incorporates mitigation strategies into its project plans, allowing teams to swiftly adapt if supply issues arise.
Early engagement supports a modular construction approach, where components are designed, fabricated, and tested off site before being delivered and installed on site. By participating early in the engineering and procurement process, teams can align design decisions with manufacturing capabilities resulting in faster assembly, improved quality control, and greater efficiency on site.
A manufacturing mindset
With a growing network of offsite prefabrication facilities, Exyte manufactures its own core modules including electrical, mechanical, and integrated systems under controlled conditions. This not only improves quality and consistency but also reduces onsite labor requirements and construction risks.
Exyte continues to invest in its in-house engineering and manufacturing capabilities to deliver high-performance, future-ready infrastructure solutions as standard. “The expectation in the near future is for an aggressive increase in the proportion of our buildings to be built off-location on satellite sites, modules built in factories and brought to location,” says Favillier.
“When we modularize, we operate with a manufacturing mindset. We are tracking timelines closely, anticipating issues thanks to lean production management, and addressing these issues before they happen to help keep timelines on track.”
Controlling the end-to-end process from procurement through installation and de-risking delivery is a pivotal advantage. This approach to supply chain management helps ensure Exyte can deliver AI-ready infrastructure at pace, transforming uncertainty into a confident commitment that clients can rely on.
Providing built-in flexibility
As AI adoption accelerates, so is the pace of change within every aspect of the data center. Today’s workloads are more power and cooling intensive than ever before, and facilities must be designed to evolve alongside demand. As such, flexibility is a mission-critical priority.
From layout to mechanical systems, built-in flexibility allows operators to adapt to changing demands without major disruptions to the infrastructure. Modular construction supports this agility by allowing large elements of the data center to be pre-assembled and delivered as complete units, ready to go as soon as they arrive on site.
One of the most pressing examples of the need for flexibility is cooling. As data centers transition from traditional air cooled systems to liquid or hybrid methods, many legacy facilities are proving difficult to retrofit. New designs must not only support today’s workloads but anticipate tomorrow’s requirements.
Exyte is addressing this by making modularity the foundation of its designs: “We are consistently looking at smart ways to modularize data centers, not just for specific components, but for the entire structure,” says Favillier.
“That way, when clients need to increase their power or cooling capacity, they can scale by simply adding another module set. This is all designed to be stacked, expanded, and upgraded like Lego blocks.”
Balancing standardization with customization is also key. By standardizing core modules and processes, Exyte creates efficiencies across quality control, assembly, safety, and installation. This reduces rework, enhances consistency, and accelerates project timelines, while allowing operators to tailor layouts and performance features to meet specific business needs.
Quality control is another core benefit of this approach. By manufacturing modules in controlled environments, inspections and quality tests can be conducted before components ever arrive on site.
Once delivered, these plug-and-play systems are connected, tested, and commissioned with minimal disruption. The result is a faster, more predictable construction timeline and a data center built to perform from day one and fit to scale up in the future.
The value of a global footprint
In a supply-constrained and highly specialized industry, global reach offers a significant strategic advantage. With operations across strategic markets, Exyte can tap into a broader network to source materials and components, manage regional cost fluctuations, and deploy expert teams on the ground wherever they are needed.
A global footprint also enables a consistent approach to project delivery, regardless of location. Exyte prioritizes standardization across engineering, construction, and project management so that each and every project reflects the company’s commitment to quality, safety, and innovation.
This consistency in approach provides a level of predictability where customers know what to expect, whether building in Asia, Europe, or North America. For companies expanding into new geographies, having a trusted partner that can replicate a successful model across borders is invaluable.
The ability to deploy local expertise on a global scale throughout each stage of a project, means the company can track progress in real-time, identify bottlenecks early, and keep projects moving forward.
From design through to delivery, this boots-on-the-ground model helps enforce global best practices for health and safety, ensuring that even in local markets, projects meet international standards, and every undertaking is delivered with safety as a top priority.
Leveraging vendor relationships
Soaring demands bring expanding supply chains. The industry is experiencing a rush of new entrants – namely vendors and service providers looking to capitalize on growth. While this has sparked innovation, it’s also made reliability and consistency harder to guarantee.
To maintain control and reduce risk, Exyte emphasizes two strategic approaches: building internal capabilities and developing strong trade partnerships. On the self-sufficiency side, the company is increasingly taking responsibility for scopes traditionally handled by subcontractors, such as having its own in-house module manufacturing capabilities allowing it to better manage project timelines, costs, and safety standards.
Equally, Exyte recognizes the value of strategic partnerships working to shift from transactional relationships to long-term collaborations and evolving from subcontractor roles to trade partner mindsets.
“We are looking to bring our partners along with us,” explains Favillier. “It’s about developing mutual trust and raising standards together, over time, especially as we grow into new regions.”
This includes blending global suppliers with local contractors. International vendors bring scale and consistency, while local partners contribute essential knowledge of building codes, labor regulations, and health and safety practices specific to the region. Together, these partnerships enable Exyte to maintain consistently high standards while adapting to local nuances.
It’s clear that, in today’s uncertain landscape, where geopolitical tensions and economic volatility can cause ripple effects across global supply chains, having a clear strategy and the right partners is essential.
AI has ushered in a new generation of complex challenges, as well as exciting opportunities. Facilities must be built faster, perform better, and possess the capacity to evolve continuously. In this environment, combining speed with foresight and flexibility is foundational to long-term success.
Exyte is helping operators meet demand and overcome primary obstacles with an approach rooted in innovation, forward-thinking, and strategic collaboration. Through modular design, global reach, early procurement, and strong partnerships, Exyte is well-equipped to deliver the AI-ready infrastructure of tomorrow, today.

UK ventilation manufacturer Nuaire will proudly be displaying its sustainability credentials at this year’s UK Construction Week at the NEC, Birmingham, 30th September – 2nd October, on stand D71.
With increasing emphasis being placed on reducing embodied carbon within mechanical, electrical, and plumbing (MEP) systems – which are estimated to account for around 23% of a building’s embodied carbon – Nuaire is leading the ventilation industry in its drive to substitute high carbon materials with more sustainable alternatives, without compromising performance, reliability, or indoor air quality.
Nuaire is the first UK ventilation manufacturer to switch to recycled and renewably produced XCarb® steel across its BPS air handling units and XBOXER XBC packaged heat recovery systems, the latter of which will be on display at UK Construction Week. This shift will result in a 64% reduction on the steel proportion of Nuaire’s SCOPE 3 embodied carbon activity within the first year alone, compared with the same steel manufactured via the conventional steelmaking route.
Similarly, plastics used in residential ventilation systems and ducting often rely on virgin fossil-based polymers. Nuaire has changed to recycled plastic for its ducting, which will also be displayed at the show, along with Ductmaster Thermal all-in-one thermal ducting solution Nuaire’s metal air brick range for use in high-rise residential buildings.
In line with the sustainability theme of Nuaire’s stand at this year’s UK Construction Week, the latest evolution in Nuaire’s Drimaster-Eco Positive Input Ventilation (PIV) unit will be revealed. Highly effective at preventing condensation dampness, PIV technology was invented by Nuaire over 50 years ago, and continues to be developed for greater efficiency and sustainability. With Awaabs Law coming into force on the 27th October in the social rented sector, and being extended to the private rental sector, Drimaster remains a highly effective solution for landlords to prevent damp and mould.
Of course, ventilation doesn’t just protect against damp and mould, it is effective in addressing overheating, a more modern day issue to be found in many urban high-rise new builds. Nuaire will be showing its Hybrid Cooling System at UK Construction Week, which has been designed to tackle residential overheating in properties where window openings are limited and insufficient to naturally ventilate excess heat. The Nuaire Hybrid Cooling unit works in tandem with its MRXBOX MVHR. It activates when indoor temperatures exceed a threshold—typically 23°C—and introduces pre-cooled fresh air to help maintain occupant comfort.
Also on display at this year’s UK Construction Week will be Nuaire’s Faith-Plus from decentralised mechanical extract ventilation (dMEV) fan, designed to provide Building Regulations compliant continuous background extract ventilation for social housing.
Providing customers with a true breadth of ventilation solutions and expertise, whether it be the residential new build sector, social housing or commercial applications, Nuaire ventilation systems are renowned for saving energy and improving indoor air quality.
Nuaire is part of the Genuit Group of businesses which serve the construction industry.

A dilapidated railway station building has been brought back from the brink of dereliction with a little help from Welsh Slate.
Some 16,000 of the leading UK manufacturer’s 500mm x 300mm Ffestiniog Blue Grey Capital-grade slates now adorn the roof of the historic Grade II listed Cambrian Railways Building in the market town of Oswestry on the Shropshire/Welsh border.
It has been three years since the building has been properly visible as it was shrouded in scaffolding following storm damage in 2022 when a number of eaves corbels became loose. These are specifically referenced in the Listing by Historic England and are a key feature of the building.
Funded by the UK Shared Prosperity Fund and owners Shropshire Council, this £630,000 phase of the renovation scheme has been completed in nine months by local building conservation specialists Phillips and Curry in conjunction with consulting architectural technicians Donal Insall, Cambrian Heritage Railways, Oswestry Town Council and the Future Oswestry Group.
Work has included removing dangerous asbestos roof tiles and replacing them with 750m2 of the ones from Welsh Slate’s Ffestiniog quarry, and restoring the building’s exterior to prevent falling masonry, as well as giving windows and doors a fresh coat of Cambrian Railway colours.
The scheme has also included installing nesting boxes for swifts under the eaves as well as bat roosting tiles along the roof which features six large chimneys and multiple hips and valleys. The Ffestiniog slates were graded into four thicknesses by Philips and Curry before they were laid and fixed with large-headed copper clouts.
Due to the tight site, Philips and Curry installed a haki scaffold stair to improve roof access for site operatives, along with a rack and pinion goods hoist to safely lift all materials to roof level.
The Cambrian Station Building boasts a rich history that stretches back to the mid-1860s. Once serving as the local railway station and the Cambrian Railway headquarters, it was key in connecting Oswestry and North Wales. Though still used seasonally by the Cambrian Heritage Railway, the building needed major investment to stay safe and functional.
Shropshire Council’s property management arm, Property Services Group (PSG), found the original Victorian roof, which would have been Welsh Slate from the quarries served by the Cambrian Railway, required significant repair and restoration.
A report by the council’s Historic Environments team identified several areas of “large-scale damage” caused by rainwater from the leaking roof, along with what they described as “the combined effect of material saturation, construction defect, inappropriate intervention and poor maintenance.”
Significant renovations had been made in the 1970s but these included the replacement of the original Welsh slates with a ceramic composite tile which contained asbestos, and the removal of many of the building’s architectural features.
It was originally thought it would be possible to save most of the nearly 300 existing eaves corbels by just replacing the worst of the delaminating and loose ones, but after thorough testing and trialling on site, it was decided longevity of repair could not be guaranteed.
Shropshire Council sought building consent and instructed Phillips and Curry to remove all 300 corbels and install new. These were moulded and manufactured from eco-friendly Jesmonite which is identical in appearance to the original Roman cement but is a more stable casting compound.

Philips and Curry director Michael Curry, a heritage roofer by trade, said:
“The roofing itself was straightforward. What was challenging was the long duration of time required in between stripping the roofs and then recovering them, which was approximately four months due to structural repairs to the roof structure and that all the new cast corbels needed to be fitted before the fascia boards could be fixed. It was a challenge keeping the building dry with temporary tarpaulins.”
He added:
“The Ffestiniog slates were great to lay. We are immensely proud of our heritage roofers for completing this exacting work and two weeks ahead of programme.”
Further structural work is required to its interior subject to further grant funding being available but, in the meantime, the Cambrian Heritage Railways have started their summer programme.
Shropshire Council has said it will be working to determine a long-term use for the building, with a scheme of internal improvements to bring the building up to a rentable standard.
Its senior project management officer Peter Gilbertson said:
“We’re so pleased that the scaffolding is finally coming down, and in time for Easter. This building holds significant cultural value for our community, and these essential repairs ensure it remains safe and usable for future generations.
“Since taking on the ownership of the building in 2023 lots of progress has been made. Whilst the scaffolding was in place we made some of the more fragile parts of the building safe, while retaining and reinstating its historic features where necessary. It really is a beautiful building and we’re proud to be involved in securing its future.”

Tom Copley, Deputy Mayor of London for housing and residential development
London’s failure to build even a third of the affordable homes it is meant to is down to the Building Safety Regulator (BSR) and former housing secretary Michael Gove, according to the capital’s deputy mayor for housing.
Tom Copley said the way the BSR – which regulates the construction of higher-risk buildings – was set up has led to “unacceptable” delays in building, partly due to its capacity and partly because of its interpretation of new post-Grenfell building safety regulations, he claims.
Work has only started on 5,535 affordable homes in London since 2021 – less than a third of City Hall’s target of 17,800 by 2026.
However, Copley said he was still “very confident” the mayor would hit the target – which was downgraded last year following an agreement with the Ministry of Housing, Communities and Local Government (MHCLG) – and anticipated a “surge” in starts towards the end of this year.
He told the London Assembly housing committee:
“We are in an enormously challenging economic context, with some factors affecting London specifically.
“These include record material costs partly due to the war in Ukraine, increased labour costs due to Brexit, and 14 years of disinterest in affordable and social housing from the last government, and in the social housing sector in general.
“High interest rates have affected both supply, in terms of the cost of borrowing, and buyers, in terms of mortgage costs.
“Developing flats is more expensive and uncertain than houses – that has been affected particularly by high interest rates. Flat development in London makes up 96 per cent of our new homes compared to 17% in the rest of the country.
“While the mayor supports the principle of the BSR, the way it was set up by the previous government has led to absolutely unacceptable delays. This government has begun the process of reforming the BSR so we do expect that to improve.”
Last month Sir Sadiq Khan came under fire for his record after new figures revealed that just 347 new affordable homes were started between April and June this year.
The mayor has taken aim at the BSR as a primary factor in the lack of spades in the ground, saying last week that the “regulator hasn’t been fit for purpose”.
Copley told the committee:
“The BSR doesn’t have the capacity necessary to operate. The way the BSR has interpreted regulations has not been particularly helpful and I am very hopeful that the new leadership are going to be able to make the necessary changes.”
A BSR spokesperson told the LDRS:
“We don’t recognise this interpretation of our approach to enforcing regulation aimed at avoiding another tragedy like Grenfell.
“Most of the delays have been caused by developers failing to demonstrate their plans comply with longstanding regulations.
“We are working hard to speed up our processes while supporting industry to understand what they need to do. Ultimately, it is for developers to show their plans are safe, and already we are seeing more of them doing so successfully.”
In June, the MHCLG unveiled a new package of reforms for the BSR and appointed Andy Roe to help “evolve and improve” practices.
Sources at the Health and Safety Executive, which established the BSR in 2022, told the LDRS:
“The most significant cause of delays right now is the quality of applications from developers. However, around 70% of applications fail to do this and are therefore rejected.
“We accept the enforcement of building control standards by BSR has delayed some higher-risk building approvals. However, not enforcing the law risks the safety of residents in high-rise buildings. The purpose of the Building Safety Act, 2022 is to prevent the failures that led to the Grenfell tragedy ever happening again.”
Copley also suggested Gove’s delay in signing off the Affordable Homes Programme for London meant the capital was playing catch up.
The former Tory Housing Secretary did not rubber stamp the scheme until July 2023, with City Hall saying that work could not start on the new wave of affordable homes until later that year.
“We have had just 18 months,” Copley told assembly members. “For circumstances out of the mayor’s control and due to the previous housing sec, the [housebuilding] figure is not higher.”
Despite the issues, Copley said he was bullish on London’s future when it came to building affordable homes.
He claimed there will be the “usual hockey stick effect” – a sudden, sharp increase – in the final quarter of 2025 “because there is a very strong incentive for partners to meet the deadline in order to access funding”.
In July, the MHCLG announced that London will receive up to £11.7billion over ten years, 30% of the total national fund, to invest in building new homes for families on lower incomes.
Heat-reflecting insulation could help ease discomfort as fourth heatwave hits UK
In the middle of the fourth heatwave of the year in England, insulation specialist Actis is reminding specifiers that installing certain types of insulation can actually help reduce the impact of extreme temperatures.
Amber heat health alerts are in place for parts of central and Southern England, with temperatures of up to 34 degrees hitting some areas.
“We all need to prepare to cope with the impact of the UK’s now regular heatwaves,” explained Actis UK and Ireland sales director Mark Cooper. “Specifiers and builders need to futureproof the homes they build, and homeowners need to look at retrofitting where possible to ensure that as well as keeping them warm in winter, properties stay cool in summer.”
Some forms of insulation can make homes unbearably hot during heatwaves, but others, such as those in the Actis Hybrid range and its two-in-one Eolis HC, can actually keep them cool, as well as still performing their traditional warmth-maintaining duties in the winter.
All Actis products have been specifically designed to help buildings stay cool, as well as warm, with the reflective films from which Eolis HC is created reflecting 95% of infrared radiation.
Mark added:
“Architects are obliged to limit unwanted solar gains and provide a way to remove heat from residential dwellings under Part O of the building regulations. As well as strategically siting windows in new builds and drawing curtains, installing reflective insulation can help protect the health and comfort of the occupants.”

Presented as part of the Time, Space, Existence exhibition organized by the European Cultural Centre (ECC) in Venice, the Diamanti bridge is the result of a multi-institutional collaboration led by Professor Dr. Masoud Akbarzadeh, his team at the Polyhedral Structures Laboratory (University of Pennsylvania), and Sika Group Switzerland, led by Karolina Pajak.
The small-scale prototype of the structure was fabricated by the Dutch firm Vertico, while the 10-meter version was 3D printed by Carsey3D in France. The bridge is composed of nine prefabricated concrete segments, 3D printed using a robotic arm and a two-component cementitious mix developed by Swiss construction chemicals company Sika. The geometry of each segment includes voids and surface articulation that support structural performance and enhance sustainability metrics by lowering embodied carbon. These segments are held together by eight ungrouted steel cables, forming a post-tensioned system that is functional and reversible. No adhesives or grout are used in the connections, making the bridge entirely demountable and recyclable.
The project explores the future of construction through computational geometry, modularity, and additive manufacturing. Engineered around funicular logic and fabricated using robotic 3D concrete printing, the 2.5-meter-long bridge model offers a glimpse into how architectural spans can evolve toward material efficiency and demountable systems.
3D-printed Concrete Construction Uses Polyhedral Forms
Drawing on the design method of Polyhedral Graphic Statics (PGS), the Diamanti project channels compressive and tensile forces through a polyhedral form optimized for performance with minimal material. The geometry of the structure is shaped by force flow and fabrication constraints and integrates anticlastic diamond surfaces that stiffen the segments, distribute loads, and reduce concrete usage without sacrificing integrity.
While the version on display at the seventh edition of ECC’s Time Space Existence in Venice spans 2.5 meters with a slim 26 cm depth, the design led by Professor Dr. Masoud Akbarzadeh has been successfully tested at a full 9-meter span, underlining its scalability. The underlying concept proposes a rethink of how construction systems can reduce reliance on massive reinforcement, cut material waste, and favor ease of disassembly. The Polyhedral Structures Laboratory team integrates computational design with innovative material systems.
The Diamanti bridge reflects a systems-based approach that links academic research with industrial application. Each phase of the project was carried out through a network of collaborators. Sika Group developed a customized cementitious mix tailored for robotic extrusion. Carsey 3D printed the parts and managed the logistics of fabrication and assembly, while post-tensioning expertise was provided by AEVIA. Structural modeling and analysis were conducted independently by researchers at City College of New York and Villanova University, and physical load testing took place at the CERIB institute in France.
Diamanti should be understood as a working prototype, a testbed for modular construction methods that focus on material efficiency, reversibility, and low-carbon performance. Its design is driven by a logic of force distribution, demonstrating how structural performance, ease of assembly, and future disassembly can be integrated within a single prefabricated system.
WORKS COMMENCE FOR 80,000 SQ FT GATEWAY OFFICE REDEVELOPMENT IN LEEDS CITY CENTRE
Prescient Capital has announced the start of construction for the redevelopment of Wellington Plaza, a significant office building in the heart of Leeds’s premier business district.
Cleggs Construction has been appointed as main contractor to deliver the redevelopment which will see demolition of the existing 1980’s built, four-storey building to make way for a new state-of-the-art, eight-storey development comprising 80,000 sq ft of Grade A accommodation.

Morgan Sindall Construction and Merthyr Tydfil County Borough Council are celebrating significant progress in the delivery of the pioneering Net Zero Carbon refurbishment of Pen-y-Dre High School, with final handover scheduled for 2026.
The project represents one of Wales’ most ambitious school refurbishment programmes, transforming the 1970s building into a state-of-the-art educational facility whilst maintaining its operational status throughout the three-year construction programme.
The comprehensive refurbishment has included new roofing, cladding, windows and external doors, mechanical and electrical works, internal alterations, internal finishes, fixed furniture and fittings, and extensive external works across the 11,250m² site. The project has been delivered through six phased stages to ensure minimal disruption to the pupils and staff who have remained on site throughout construction.
A key highlight of the transformation is the installation of a substantial photovoltaic array, which will not only support the school’s Net Zero Carbon status but also provide surplus energy to the neighbouring Prince Charles Hospital and Goetre project via direct wire connection. The innovative approach has already delivered 619 tonnes of carbon savings through operational efficiencies.
The decision to refurbish rather than rebuild was driven by environmental considerations, with the refurbishment approach delivering four times less carbon impact than a new build whilst preserving valued facilities including the school’s swimming pool, two dining halls, and two sports halls.
The project team, comprising Lawray Architects, Cambria (civil and structural), WSP and High Admit (MEP services), and Mark Morant Sustainable Design (Net Zero Carbon consultant), successfully addressed complex site challenges including asbestos, structural issues, and contamination whilst improving circulation and widening corridors throughout the building.
The refurbishment has surpassed key performance targets for social value across multiple indicators. Highlights include 3,389 New Entrant Training opportunities – ranging from graduate roles to work placements and pupil engagement – alongside the creation of 42 new entrant jobs. Additionally, 95% of the labour force has been sourced from within the region.
Robert Williams, Area Director from Morgan Sindall Construction in Wales, said:
“This key milestone at Pen-y-Dre High School marks the culmination of an extraordinary three-year journey. This has been a truly pioneering project – the scale and complexity of delivering such a comprehensive transformation within a live school environment cannot be overstated, and our teams have responded with exceptional skill and dedication throughout.
“What makes this project especially significant is the legacy it leaves behind – not only are we creating a world-class educational facility for future generations, but we’re also setting a powerful example of how sustainable refurbishment can dramatically reduce carbon impact, preserve valued community assets, and deliver meaningful benefits for the local economy.”
Sophie Jenkins, Sustainable Communities for Learning Programme Manager at Merthyr Tydfil County Borough Council, said:
“Some people who would tell you that a refurbishment project could never be as good as a new build project. After working with Morgan Sindall I’m not one of those people.
“I’ve been astounded at the quality of the final works their team have been able to produce. Working together has felt a genuine collaboration too.
“The teaching and learning environment is exactly what is needed to deliver the new curriculum for Wales and facilitate new community activities.”

EcoCocon and Ecological Building Systems announce exclusive partnership to expand straw panel construction in the UK & Ireland
In a significant move for sustainable construction, EcoCocon, a leading European manufacturer of prefabricated straw wall panels, has entered into an exclusive partnership with Ecological Building Systems, a well-established distributor of sustainable building materials in the UK and Ireland.
The partnership will make EcoCocon’s innovative straw-based wall system more accessible to professionals across the UK and Irish construction markets — combining bio-based innovation with localised technical expertise.
EcoCocon’s modular wall panels are made primarily from compressed straw and timber, offering Passive House-level thermal performance while significantly reducing embodied carbon. The system is robotically manufactured in Europe to ensure precision, consistency and scalability — making it a viable solution for both single-family homes and large-scale developments.
With the addition of EcoCocon to its portfolio, Ecological Building Systems will provide full distribution and technical support, including design consultation, detailing, training, and on-site assistance.
“We’re proud to partner with EcoCocon to bring this next-generation ecological wall system to our region,” said Penny Randell, UK Director and General Manager at Ecological Building Systems. “It aligns perfectly with our mission of supporting healthy, low-impact buildings through science-led guidance and proven building solutions.”
Adrian Crosson, Irish Director & General Manager at Ecological Building Systems, stated:
“From the beginning, Ecological has focused on low embodied carbon solutions that are durable, purpose-fit for the UK and Ireland, and supported by expert technical guidance from design through to construction. By combining EcoCocon straw wall panel systems with our trusted technical support, we’re making sustainable building more accessible and achievable than ever before.”
EcoCocon has been used in hundreds of projects across Europe, from schools and apartment buildings to custom homes and co-housing developments. The system is fully certified, supports circular construction, and is designed for fast on-site assembly, reducing build time and waste.
“This partnership marks a key step toward scaling up ecological construction,” adds Paul Lynch, International Sales & Network Manager at EcoCocon. “Our aim is to make sustainable, low-carbon buildings not only possible, but practical. With Ecological Building Systems, we have the right partner to support that journey in the UK and Ireland.”
The two companies emphasise that this collaboration is about more than materials — it’s about enabling the construction sector to meet the growing demand for climate-conscious, human-centric buildings.
