‘Passivhaus’ extension

Low energy renovation of a bungalow in Rottingdean including loft conversion and side extension. The existing roof was transformed by stripping back to the frame to utilise all internal space, adding deep rafters alongside the existing to super insulate with 300mm of Warmcell (cellulose insulation). High performance airtightness, windtightness and triple glazed rooflights complete the building envelope.  More details and images
