Rear elevation: We designed a full-width, 3 meter deep rear extension. Roof: Part of the extension roof is a balcony that can be accessed from the master bedroom. We created a wild-flower roof with the remaining roof space which can be viewed from the master bedroom and stairwell window. Materials: Most of our bricks were re-used from the demolition stage and some were reclaimed to match existing. Sliding doors: We used an IQ Glass heated double glazing door, in winter it also functions as a radiators.
