One of U.K.'s leading architectural firm Alison Brooks Architects has extended a 19th century home in north London with two tapered volumes that project into the garden.

Description by Alison Brooks Architects:

The first volume wraps around the brick walls at the side and rear of the house to create a home office, while the second volume extends out at the back to increase the size of the first floor living room
