We have recently received planning permission for this house extension in Wiltshire. The existing Edwardian house had been subjected to a series of piecemeal additions which required updating to improve the living spaces and the energy efficiency of the house. Our design has created a single storey, flat-roofed extension which utilises the existing foundations of two of the old additions. The flat roof and material palette create a more cohesive design which sensitively compliments the existing house.
