This was a draughty uninsulated house with poor windows and a poor heating system, which had small cellular rooms and poor connection to the rear garden. The challenge was to create a low energy use house, with bigger spaces, more light and a connection to the garden.
The new extension was designed to balance allowing sunlight in and accessing views to the garden with creating an efficient thermal envelope. This was achieved by careful design of rooflights, clerestory windows strategically aligning glazing with internal zones where occupants would spend most of their time, rather than having extensive swathes of glass.
An attic bedroom was constructed. To keep the roof tiles in plane with the adjoining semi detached roof, new rafters were constructed 35mm lower than the originals to allow a counter battened roof, giving a robust sloped ceiling construction with intelligent vapour control layer (ISOVER Vario), ISOVER Metac Mineral Wool insulation and outer breather membrane.
We think that this project achieved a very balanced synthesis between contemporary design and energy efficiency, which are the 2 aspects of building in which we particularly strive to achieve high standards.
