Founded nearly 65 years ago, CATS College is an innovative independent education provider with four campuses across the UK and USA, and provides residential education to students studying GCSEs, A Levels and International Baccalaureates. With the continued success of CATS College and its growing number of students, the Canterbury campus identified the need to expand its accommodation facilities as well as its social and catering spaces.

A new student accommodation block was commissioned to offer 87 en-suite rooms, a café, common room and flexible social areas for the students. The project had a tight timeline to ensure a handover date to coincide with the academic year, and needed to be completed within just 14 weeks, so speed of build was paramount.

Another key consideration of the project was the design. With CATS College’s prestigious locations and buildings, it was important that the features of the new building complemented the existing architecture and blended in.

Atkin Trade Specialists was awarded the framing element of the contract, and used voestalpine Metsec plc’s Metframe solution to overcome the complex structural design challenges as well as achieve the tight timescales. Metframe is a pre-panelised system which is used to provide the load bearing structure for low to medium rise structures. The system uses stud, track and zed ledger sections which are bolted together off site to form panels providing the benefit of speed of build, with Metframe structures regularly taking under two weeks per floor to construct. Each structure is bespoke to allow flexible architectural design as well as to complement the surrounding buildings on campus. The building design incorporated several traditional features such as large bay windows with castellation, feature stone-work and mansard roofs, inspired by the existing architecture of the adjacent buildings.

The complex mansard roof configuration had multiple valleys and hips that needed to be incorporated into the design and the flexibility of the Metframe solution meant that the roof for the project could be formed using steel. It’s a competitive solution; rather than needing to commission a second company to design and form a roof, Metsec could supply one package, including a steel roofing solution, which added value and provided significant time savings to the project.

Inside, the building was designed to be future-proof. Internal walls were left out in the build to provide flexibility and enable rooms to be opened to form larger ones if required. This element had to be accounted for in the design and hot rolled steel beams were integrated into the design to provide this flexibility.

The detailing process involved in the design began with the import of the architectural CAD modelling into a bespoke 3D environment. This determined all setting-out and allowed structural components to be fully modelled in this environment. In turn, this enabled Metsec to precisely manufacture all of its components according to the agreed design. Manufactured at its UK facilities to the design specified lengths, even the holes in the product are punched that are required for both off-site panel assembly and on-site final build. Atkins selected the Metframe solution for its ability to be prefabricated off-site enabling the onsite construction to be completed by only five personnel in just 13 weeks, a week ahead of schedule.

The CATS College project demonstrates a broad range of environmentally friendly material and processes. The cold rolled steel used in Metframe offers an excellent strength to weight ratio meaning that not only did the project require less steel overall, but the lightweight structure required shallower foundations to be installed, providing material, time and cost savings. In addition, the structural components are manufactured to the precise length required reducing site waste.

James Gallear, of Atkin Trade Specialists, says “This project not only meets the client’s current design requirements, but it exceeds them by providing a future-proof solution.

“The modern design provides flexible additional space for the college, coupled with the architectural reflection of existing buildings on campus meaning that it blends in with the style of the surroundings buildings.”

Ryan Simmonds, sales director of Framing at Metsec, adds “This project challenges the common perception of the type of building which is suitable for off-site construction. With special design elements such as the mansard roof at CATS College, installers will often disregard the off-site option, but our project with Atkin Trade Group shows that off-site can not only be an efficient and cost-effective solution, it can also provide solutions to complex architectural designs.”

Leading commercial washroom designer and manufacturer, Washroom Washroom, has created an iconic new cycle centre for a central London office.

214 Grays Inn Road comprises 45,500 square feet of mainly car parking space as well as back up accommodation for 200 Grays Inn Road, both of which were acquired by The Great Ropemaker Partnership (GRP) in 2011 and have since undergone a period of extensive refurbishment led by architects IMA.

Washroom Washroom, having installed new washrooms on floors four and six of 200 Grays Inn Road previously, was approached to create the new bespoke cycle centre at number 214, designed to cater for tenants at 200 Grays Inn Road.

The innovative modular cycle centre was designed by IMA and in addition to bicycle parking, it provides separate male and female showers and changing rooms. The digitally printed bicycle x-ray style artwork at the entrance to the centre was an original, specially commissioned, piece of art by renowned artist, Nick Veasey.

Washroom worked closely with interior design and fit-out company Elev8 Interiors Ltd to create the new cycle centre. The company’s Forza lockers, which were manufactured from 12mm solid laminate with aluminum bodies for exceptional strength, were installed and come complete with digital code access locks.

The cycle centre also features Washroom’s highly engineered Marcato toilet and shower cubicles, fitted with high-quality stainless steel locks and coat hooks. Its flush fronted design and rebated finish ensures division panels and doors meet edge to edge for maximum privacy while the waterproof properties of solid grade laminate make it an ideal choice for toilet, shower or changing cubicles.

The bespoke Corian trough vanities, with their seamless, natural, stone-like appearance, provide a luxurious, highly durable finish to complete the look.

Trevor Bowers, director at Washroom Washroom said: “There’s been a huge increase in demand for staff shower and changing areas in recent years and this is something which has fast become a core part of our commercial offering. This project highlights our ability to deliver more than washrooms!”

Centralised plant rooms for heating and hot water systems are a traditional solution and have been so for many years. But we live in different times where economic and energy efficiency – and legislative compliance – are demanded by users, premises owners and managers in both public and private sectors.

An alternative solution that marries high efficiency and wide ranges of modulation with simplicity of installation and design is the gas fired continuous flow hot water heating unit. These can be manifolded into a hot water system capable of coping with virtually any size of site or application. This system is a process of delivering a continuous flow of hot water at a constant temperature, without the need for storage. Continuous flow will only ever utilise energy whenever heat is needed i.e., the turning on of a tap in a washroom or a kitchen. When the units are in operation and heating water – gas is used – when the user is finished, so is the energy usage. With continuous flow systems, the user can set the required temperature of hot water to suit the needs and demands of the site. So, vulnerable users, such as children, the elderly or less able, can be safeguarded from the risk of scalding. Also, where the site has a secondary recirculating system the temperatures can be set at a level to further minimise the possibility of the proliferation of Legionella bacteria.

Condensing continuous flow hot water solutions qualify for additional energy efficiency points, boosting building energy performance as they far exceed energy efficiencies called for in Part L Building Regulations (Conservation of fuel and power). The systems are also ‘A’ rated under ErP.

Current thinking on the design of systems is moving towards separating the hot water production from the heating system completely as it can give better efficiencies all round. Buildings need hot water all year round. However, better insulation in most buildings, and a greater awareness of energy efficiency, means there is a reduced need for heating input.

In large commercial buildings, centralised heating and hot water systems have traditionally adopted the thermal storage design. These systems are frequently over-sized at the design stage in relation to actual usage on the not too scientific basis of ‘just in case’. This ‘hedging of bets’ approach to system design often leads to excessive safety margins, which in turn adds to the expense of purchase, installation and running costs.

A storage type, conventional system of hot water that must be heated 24/7, 365 days a year to ensure hot water is always available is an anachronism in today’s energy and cost-conscious world. Even if no hot water is drawn off, a standard cylinder, just for example, can lose a maximum of 3Kw of heat a day as a standing loss.

All cylinders suffer from this to some extent and it equates, over a year, to 1095Kw of energy wasted. If you also look at the gas saving alone it equates to 101.8m₃ of gas used.

Decentralised hot water provision was recently installed at a luxury country club and spa in the leafy and very affluent Cheshire countryside. The site operators, having both the contractor and the consultant make calculations on usage and life cycle costings, was adamant that a stored hot water system was not in the frame for the new fit out as it would be “inefficient and expensive”. The company went on to specify 19 gas fired condensing continuous flow units over the whole site to fulfil its huge demand for 20,000 litres per hour of safe, temperature controlled hot water. The heavy-duty units feed executive soaker showers, poolside showers and all changing room ablutions.

Within this complex, the water heaters feed the showers directly so there is no need for re-circulation around the building. With no centralised boiler room having to be incorporated into the plans.

Elsewhere, one local authority in North Wales is currently in the process of replacing its stored hot water systems with manifolded continuous flow systems. The council is set to make considerable savings on running costs. When the water isn’t running the continuous flow, system is not using fuel, which is ideal for the schools’ shut down during the holidays, for example.

These claims and assertions have been borne out by independent scrutiny. Recent independent testing – by AECOM – of continuous flow hot water systems showed a clear advantage in terms of initial capital costs, as well as life cycle costs over 20 years, when compared with indirect stored and stored hot water systems.
The AECOM findings, after extensive deliberation, found that the brand’s continuous flow water heaters are 7.5% more economical than ‘traditional’ stored hot water systems.

Decentralised water heating saves energy and money, but it also offers flexibility. If, for example, a hot water store cylinder should burst or break down, the whole system is shut down – no more hot water until the problem is fixed. With a manifolded system one unit may be at fault but this doesn’t stop the whole system shutting down.

The problem of potential legionella proliferation is also better maintained in the design of a manifolded continuous flow system. In a continuous flow unit, water temperature for distribution is accurate to ±1˚C. The fact that there is no stratification as there is no storage ensures permanent even temperature and because of this there is no requirement to heat a volume of water just to ensure the elimination of legionella. Another plus is, if demand grows, additional plant can easily be added in a modular fashion at a later stage if required.

In addition, smart controls can be added to commercial condensing continuous flow systems to boost and govern the performance of the hot water system.

The market leading, high performance weberpral M monocouche render by Saint-Gobain Weber has been architecturally specified in the extension programme of a popular restaurant in the tourist area of the western Southern Uplands of Scotland.

Standing on the shores of the gleaming Loch Ryan, the Driftwood Restaurant is a popular venue for tourists exploring the beautiful area of Dumfries and Galloway. Nestling by the water’s edge, just minutes from the Stranraer ferry terminal that connects Scotland with Northern Ireland, the Driftwood has recently been extended and refurbished to meet the expanding “staycation” business that is boosting Scottish tourism.

Dumfries and Galloway Council are the property landlords of Driftwood who carried out a business assessment that established the need to expand the property to meet the required capacity and the commercial viability of the restaurant in servicing the local and visiting community. The design and build project was handled by DG First, the Council’s in-house construction and maintenance division, and plans were drawn up by Alan Hewitt of the Property and Architectural Services department. The design almost doubled the size of the structure using timber frame with a blockwork skin which has been finished with weberpral M monocouche render.

Factory produced to ensure product consistency weberpral M is a cementitious, through-coloured render suitable for one-coat application to appropriate brick or block work substrates. Produced from carefully selected raw materials, weberpral M monocouche render is formulated for pump application which allows quick and efficient installation. This contributes significantly to shorter programme periods, reducing associated scaffolding and site costs and permitting the completion of ground works at an earlier state. It is supplied ready-mixed with only the requirement of clean water to be added on site and is applied in a two pass operation to a thickness of 20-28mm; it is then scraped when green giving a minimum render thickness of 15-25mm.

Weber recommended applicator J & J Runcie Plasterers Limited, Stranraer, carried out the render to the new structure. “The architect specified weberpral M from the experience gained on many housing refurbishment and new build projects in the region. As an applicator, we always choose Weber products for their quality and ease of application,” reports James Runcie. “The Chalk colour selected really sets the Driftwood Restaurant off to its best in this parkland setting. We machine applied the render as weberpral M is perfectly formulated for this fast and accurate application method. We are very pleased with the finished result.”

Recent changes to the formulation of weberpral M have been designed to be fit for combat in the war against unsightly algae. Saint-Gobain Weber has worked closely with French microbiologists to understand the effect of the composition of the render and the effect that external factors have to play, such as surface condensation, temperature and rain fall. By changing the product formula as classified in EN998-1 weberpral M effectively repels water from the surface helping to ensure that Britain’s homes and buildings remain looking better for longer.

Saint-Gobain Weber is the first manufacturer of monocouche renders to be awarded an A+ rating as defined in the BRE Global 2008 Green Guide to Specification. This audited material helps specifiers to make selections that will collectively reduce the environmental impact of their buildings while achieving a higher number of BREEAM material specification credits. weberpral M has excellent weather resistance and durability whilst allowing the structure to breathe. Its through-coloured characteristic requires no decoration, is truly low maintenance and offers a variety of ways to achieve architectural features. It is available in a palette of 24 attractive colours.

With the pop-up culture seen as a flexible, fast and low-cost solution to revitalising and unlocking urban environments, Brett Martin Daylight Systems’ lightweight and robust Marlon CS profiled polycarbonate glazing panels have maximised daylight and been an integral element in the creation of Boxpark Croydon, a new pop-up mall featuring a range of shopping and dining venues.

Located next to East Croydon train station and designed by architects BDP as part of the mixed-use Ruskin Square Development, Boxpark Croydon has been built from 96 stripped and refitted shipping containers arranged around a covered courtyard space which can be used for year-round events. To bring natural daylight and to provide cover to the central piazza which has drawn inspiration from Covent Garden, the specification of single-skin Marlon CS Longlife ensured this project met the fast- build programme.

The early involvement of Brett Martin technical team on the project ensured the most appropriate daylighting solution was chosen which met the individual daylighting and aesthetic requirements of the project.

The project saw the creation of a transparent roof made up of 1331m2 of 2mm thick Marlon CS Longlife glazing panels in three pre-cut sizes and installed at a pitch of 5 degrees.

Commenting on the project, Daniel Isaac, Area Business Manager at Brett Martin Daylight Systems said; “We recommended a pitch of 5 degrees to avoid any water ingress issues in the space below and advised on fixing methods which included 2mm thick EPDM dry seal compression tape at the end laps due to longer overlaps.”

In addition to the impact resistance, resilience and structural strength inherent in all of Brett Martin’s high performance polycarbonate sheet products, Marlon CS Longlife is also lightweight and easy to handle. With an unrivalled range of profile options, it can be used to form complete roof coverings or can be incorporated into any corrugated metal roofing and cladding system, from simple single skin to advanced composite panels.

By incorporating Brett Martin’s Marlon CS Profiled Polycarbonate sheet, visitors to BoxPark will be able to enjoy a bright, airy environment that is protected from the extremes of wet weather as well as protection from the sun’s UV rays.

Offering long-term performance, Marlon CS Longlife polycarbonate comes with a co-extruded UV protection layer and carries a 10-year warranty on light transmission and durability, guaranteeing daylight into this pop-up mall for years to come.

Holiday-home owners at Haggerston Castle Holiday Park in Northumberland will be relaxing in style this summer at the Park’s new owners’ lounge, constructed from the Kingspan TEK Building System of Structural Insulated Panels (SIPs) during the short off-season period.

The Haven holiday park is situated within the lush former grounds of Haggerston Castle, with its award-winning landscape gardens and picturesque lakes. Designed with guidance from Hill Cannon to complement its lakeside position, the new owners’ lounge offers a light and modern multifunctional space with a bar, restaurant and outdoor terrace. Kingspan TEK Delivery Partners, SIP Build UK, erected the Kingspan TEK Building System to form both the walls and roof of the lounge. Chris Duckworth, Managing Director of the company, discussed the specification:

“It was vital for the new owners’ lounge to be fully complete and ready to welcome guests by the end of the closure season in March. That gave us five months, over the worst of the winter weather, to get the build completed. The Kingspan TEK Building System really comes into its own in these conditions. We pre-cut the SIPs to the project’s exact specifications in our factory. As a result, the delivery was carefully scheduled in advance and once we arrived on site, our team were able to erect the system with virtually no alterations. The panelised design meant there was no need to wait for wet trades to dry and we were able to erect the main shell in just two weeks. Once we had the shell erected and a membrane applied, the building was weathertight meaning the first fix could begin internally whilst the external cladding was being applied.”

In alignment with Haven’s dedication to preserving the natural environment, the excellent fabric performance of the Kingspan TEK Building System should also help to reduce the facilities’ energy requirements. The highly insulated core of the 142 mm Kingspan TEK Building System panels can allow them to achieve U-values of 0.20 W/m2.K and below, whilst the OSB/3 facing and unique jointing system help to minimise unnecessary air loss.

Both the Kingspan TEK Cladding Panel and Kingspan TEK Building System panels are also available in a 172 mm thickness, delivering U-values of 0.17 W/m2.K or better, without the need for additional insulation. The manufacturing facility where the panels are produced carries both FSC® (FSC®-C109304) and PEFC Chain of Custody certification.
