Mat Barnes, the director of architecture and design studio CAN, embraces creativity and new materials—including those made from recycled waste. In the transformation of his London home, he has created a design full of surprises and invention. On the ground floor, the partially demolished brick wall was inspired by the crumbling brick walls in the movie Trainspotting. The bricks taken down were relaid elsewhere in the project, and the remaining wall was painted and left as is.
