The cottage was constructed in 450mm solid brick walls with no foundations, which provided some interesting engineering considerations with regard to supporting the house once the walls were removed and tying it into the new extension foundations. With our engineer we came up with a foundation design that avoided any underpinning of the old walls and saved considerable expense, together with a fabricated steel box solution to facilitate the large openings in the walls and maintain through ventilation to the original timber ground floor.
The extension was constructed in steel frame to maximise internal headroom, whilst enabling the large spans required for the open plan area. This was then in filled with 140mm timber frame fabricated on site and insulated with Celotex, including the flat roof finished in a single layer plastic. The old timber floors were removed, repaired and replaced to install under floor heating throughout and married into the new concrete floor of the extension. The large powdered coated aluminium doors were supplied from Germany and the kitchen supplied and installed direct from Holland.
