The SSR2 Standing Seam Roofing and Cladding system by Catnic has provided a bespoke design solution for a porch detail installed across 150 homes at a housing development for Barratt Homes and David Wilson Homes in South London. According to the sub-contractor the SSR2 was chosen because it delivers a high specification finish that provides the aesthetics and performance required.
Working in partnership with Croydon Council and the Mayor of London, the high-profile development has been designed to integrate a formerly derelict site with the surrounding area of Coulsdon in South London.
For the first phase, named ‘The Farthings’, 187 homes of the 677-unit development are being delivered. Two to three storeys in height, the architecture and materials used for the homes reportedly aims to respect the character of the local area. As David Wilson Homes’ technical manager, Dave Banks, explained: “A mixed palette of materials has been used externally, the homes are mainly brick built, some are timber clad and others rendered. The roofing finish utilizes plain or slate roof tiles. For the porch detail, we were looking for a more bespoke solution.”
Originally, the construction team said it called in specialist sub-contractor Kynaston Contract Services to discuss options for a roofing detail on the project but it became apparent that there was a requirement for a canopy detail, at which point the Catnic SSR2 was suggested.
The self-supporting canopy, designed by Kynaston, comprises a 40mm x 40mm steel box support which is bolted within the window unit and supporting gallow brackets. This was wrapped in an 18mm ply board with the Catnic SSR2 fitted on to it.
Ian Kynaston, director at Kynaston Contract Services said: “The canopy feature has been installed on 150 houses so far with more to be installed. The orientation and design detail is different for each housebuilder but typically they have been big properties, often four-bed detached units.
“Because of the scale of the housing development, the steel and timber element is now pre-manufactured in different sizes including 4.4m, 5.5m, 6.5m and 8.3m, which can be called onto site easily. The SSR2 is fitted on site.”
Dave Banks concluded: “The Catnic SSR2 looks good; it ties in well with the other building materials, giving the high specification finish required for this site.
“The project has run well, Kynaston has provided the whole package involving steelwork, plywood formwork and other trades, working closely with Catnic. It really is a bespoke and quite complex detail.”
The SSR2 system is manufactured to meet all relevant legislation including load bearing for wind speed in accordance with EN 1991-4 and weather-tightness in accordance with BS 5534 Parts 1 and 2. In addition, helping to meet requirements for sustainable building solutions – SSR2 is said to be BRE Green Guide Rated ‘A’ and at end of life – the panels are 100% recyclable.
Ian Kynaston of Kynaston Contract Services, added: “Having worked with this product for over five years, as a team we are familiar with the benefits of this material. SSR2 is a very versatile system – especially for housing projects from private developments to council housing estates. Plus, there’s a 40-year warranty, which for many developers is appealing.”
