This extension is part of a general refurbishment of the garden level of a four story Mid-Victorian house; the home of a couple, one of whom is in a wheelchair following a car accident.

The side of the house faces the old mews, which has one and two story garages and workshops. The extension provides a new entrance to the flat, accessible to wheelchairs, in scale with the mews and joins the old house to the new living space. This opens out onto the garden on one side and is particularly low on the mews side, to give the impression of a garden wall.

The use of angled steel girders for the roof, supported on brick buttresses, has provided a large and airy space inside, while maintaining the very low wall on the outside. The heavy purlins above these allow for clerestory lights on the South end, which separate the roof from the wall and add to the lightness of the space.
