A snug garden annex with its own en suite

Built as a home office with its own shower room and WC, this Walthamstow studio works as a small annex too. A bespoke desk, sleek storage and an electric projector screen let the main room switch from work to film nights, and a skylight brightens the bathroom.

Corrugated cement cladding outside needs no maintenance. Inside, laminated plywood walls, a coffered ceiling and concrete-look tiles over underfloor heating give it the finish of a well-made extension, with terrazzo tiles in the bathroom.
