Terrace house with a new two-storey rear extension in matching brick and paint

A terrace house on a 22 by 75 ft lot is a common starting point. The family had outgrown it, but did not want to move: school, mosque and neighbours were all next door. A rear extension gave them a proper kitchen and two more bedrooms.

An extension is more difficult than a new house in one way: the old structure must be understood before the new one is designed. We started with a structural survey, designed a separate foundation for the extension and joined it to the old house with a movement joint.

The family stayed in the house throughout. Noisy work was done between 9 am and 5 pm, and we cleaned the site every evening.

“We were worried about living through a building site with small children. The crew cleaned up every evening and kept the front of the house usable. It felt like a much shorter project than it was.”
