Key projects by Sou Fujimoto photographed by Edmund Sumner

Slideshow feature: following the news that Japanese architect Sou Fujimoto is designing the 2013 Serpentine Gallery Pavilion, here's a look at some of his best-known projects, including the Final Wooden House made from chunky timber beams and the Tokyo Apartment that comprises four house-shaped apartments stacked on top of each other.

House O is one of the architect's oldest projects and was designed as a weekend retreat in Chiba. House N was completed more recently and is a residence with three layers of walls and ceilings.

The architect's largest projects include the Children's Center for Psychiatric Rehabilitation, a treatment center for mentally disturbed children, and the Musashino Art University Library with walls made of timber shelves.

Sou Fujimoto also recently completed House NA, a residence with hardly any walls, and was part of the team that won a Golden Lion at the Venice Architecture Biennale for designing housing for those made homeless by the 2011 disaster. See more architecture by Sou Fujimoto.
