Matthew Lloyd Architects were commissioned by Sanctuary Housing Association to design a scheme for much needed new homes on a landlocked site, occupied by a disused workshop building on the Cass estate in Hackney, East London. The design aim was to achieve a balanced modern intervention that lifts and compliments the surrounding rear gardens and sensitively addresses the relationship to the existing buildings. The arrangement and form of the houses has predominantly arisen out of an intention to maximise their access to natural light. They are planned so that all their habitable rooms face south or west while avoiding overlooking. Their sloping north walls, reminiscent of the factory sawtooth roof which the houses replace, allows further access to natural light by reducing the overshadowing from the south of the houses on each other. The south facing roofs are pitched at an angle to maximise solar gain on solar panels. Internal arrangements are efficient and generous. Living, dining and kitchen are concentrated around the gardens with glazed doors leading onto terraces.
