Few are able to do "small houses" quite like the Japanese. Below is the Flat House in Tokyo by Yoshinori Sakano Architects. Completed in 2011, it was designed for a young couple in their twenties who wanted to build a home that was like a "small art museum." Looking at these photos, I bet many of you will be surprised to know that the site area is only 100.10m2. The building footprint is only 49.00m2. And the total floor area is 79.36m2. This is the kind and scale of housing that is now permissible on many of Toronto's laneways. And here, in Tokyo, you can see that it is serving as a family home. (The working kitchen is quite a contrast with the rest of the house.)
