An extension with a galvanised steel canopy

The original house is part of a curving row of terraces built just after the millennium. All the houses have a footprint which is narrow at the front and wider to the back. Each house in the row has its own mono pitch roof - giving the terrace a sawtooth profile.

The extension is designed to take advantage of these geometries - with the lines of the walls converging to offer a series of false perspectives.

The form has been deliberately twisted to take advantage of these interesting visual twists. The canopy twists on plan - and it has a flat roof. However, when standing in the garden looking towards the extension, the front edge of the canopy appears to follow the line of the pitched roof of the original building beyond.

The design is all about the canopy. Made of galvanised steel grating, it hides the glass frames, the thickness of wall and roof, and gives shade to the south - facing garden plus privacy from neighbouring gardens. .

The interior is laid out to promote the view out to the garden. The front entrance area was re-organised - pushing the utility to one side and opening up with a big sliding panel to the main family space. The kitchen is a linear design, giving uninterrupted views across the garden.
