Pet architecture is a term for the buildings that have been squeezed into left over urban spaces. Curious shapes and inventive solutions for drainage, windows and air conditioning abound. Most of all, it is the extraordinary miniature size of these shacks, store rooms, sushi bars and bike shops which makes this project so fresh. Lovingly researched by a team of very young Japanese architects, each ‘pet’ includes a humorous description, full page photograph, a map and 3d sketch.
