Japanese architect Yuji Tanabe designed a two-storey house for a family in Matsumoto, Nagano. The house is called ‘pettanco house’ which means squashed house is builded between a river and two narrow streets. The client is a wood craftsmen, so he also wanted to have an exposition space to showcase his projects. Due to the tight budget, architects have chosen a simple shape with one dormer that serves as a giant skylight and enlightens the upper floor. Main living space is located downstairs with a wood burning stove as a heart of the home.
