Catnic - David Wilson Homes

The SSR² Standing Seam Roofing and Cladding system from Catnic has provided a bespoke design solution for a porch detail installed across 150 homes at a high profile housing development for Barratt Homes and David Wilson Homes in South London. Recommended by the sub contractor, the SSR² delivers a high specification alternative to the usual glass reinforced plastics (GRP) that are specified on similar housing developments.

Working in partnership with Croydon Council and the Mayor of London, Barratt Homes and David Wilson Homes are preferred developers for Cane Hill Park. 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 aim to respect the character of the local area. As David Wilson Homes’ Technical Manager, Dave Banks, explains: "A mixed palette of materials has been used externally, the homes are mainly brick built, some are timber clad units and both feature chalk render detailing. The roofing is either plain or slate roof tiles. For the porch detail, we were looking for a more bespoke solution."

Catnic - David Wilson HomesOriginally, the construction team 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.

Designed by Kynaston, the self supporting canopy comprises a 40mm x 40mm steel box support, which is bolted within the window unit and supporting gallow brackets. This has been wrapped in an 18mm plyboard with the Catnic SSR² fitted on to it.

Ian Kynaston, Director at Kynaston Contract Services Limited said of the project to date: "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."

David Wilson Homes Technical Manager, Dave Banks, concluded: "The Catnic SSR² looks good – it ties in well with the other building materials, giving the high specification finish required over and above the GRP solutions we use on other sites.

Catnic - David Wilson Homes"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 BRE Green Guide Rated ‘A’ and at end of life – the panels are 100% recyclable.

Ian Kynaston of Kynaston Contract Services expanded on the benefits of the system: "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."

The SSR² Standing Seam Roofing and Cladding system is also suitable for conventional residential and commercial pitched roofing, and provides a wealth of performance and aesthetic advantages.
