This two-floor extension for a detached house accommodates a growing family, offering a new kitchen, dining room, gathering spaces, and five bedrooms. A centrally located staircase serves as the home's focal point, illuminated by natural light streaming through a large skylight. The materials emphasize the connection between light and space. Dark timber-clad sections contrast with light yellow London stock bricks, creating a balanced rhythm across the facades and evoking a warm sense of domesticity.
