This extension increases the ground floor area of this house in Surrey so that a new kitchen and dining / living space can extend into the garden. The starting point for the designs was playing with the suburban form of the surrounding streets, reinterpreting it in a contemporary way. The pitch roof becomes like an extruded version of the house. Inside, this forms an open roof structure incorporating roof lights, and a corner window with long views to the garden. This sits adjacent to a dining room that protrudes out of the existing house in a simple form, replacing a bay window.
