This house already had a 1980s single-storey rear extension which provided extra floor area, but it didn't make the most of the space; with a narrow galley kitchen and dimly lit dining room. Our proposals opened up the space by removing a number of internal walls and the chimney breast to create a generous, open-plan kitchen-diner and sitting area. New crittall-style glazing and a rooflight improve daylighting and the connection with the garden, whilst a new vibrant kitchen improves functionality.
