This two-storey rear extension was designed to establish strong connections between the internal spaces and the rear garden, whilst the spaces within are arranged on split levels and around a two-storey void, creating a dynamic and dramatic architecture. The rear facade was extensively glazed to allow daylight to flood into the internal areas and a gallery and bridge at ground floor level connect to an external glazed balcony over-looking the rear garden, with a more private balcony area at a lower level which is accessed from the Library and Study spaces. The new extension is separated from the existing house with a structurally glazed link which softens the transition between old and new and also allows more natural daylight to enter the existing internal areas. The existing garage was replaced by a new single storey building which accommodates a gym space and is clad with stained black Russian Redwood to provide a distinct monolithic architecture.
