Extension and refurbishment of a Victorian, two-storey coach house in Putney, South London

The house is relatively small and located on a narrow plot with a front parking area and a long rear garden. The scheme opens up at the back forming a first floor terrace and an extended kitchen/living room on the ground floor.

The ground floor originally contained two small rooms and an exterior passageway at the rear, this was all converted into a single garden room and the front garage converted into a drawing room.

The superposition of two cantilevered frames that stabilise each other enables the whole of the ground floor of the rear of the building to be open to the garden, with sliding glass doors opening neatly to the side leaving the cantilevered corner of the building free.

Transparent and open-able screens, glass roofs, doors and mirrors have been employed to draw light into the heart of the house at different times of the day and to merge inside and outside spaces.
