Kitchen-diner extension on a canal-side terrace

A young family in a Victorian terrace had a galley kitchen, a back yard and an outside toilet. They wanted one room where they could cook, eat and watch the kids play outside.

The ground floor is now one bright room. Building control signed it off first time and the family moved back into the kitchen a week ahead of schedule.
