A log building, built in 1951, has been extended to create a new residential unit. The name of the house refers to the desired atmosphere and dynamism. The Japanese garden surrounding the building is due to be completed in the near future. The design concept was a four-storey-high building with a very steep roof plane. The roof is indeed like the slash of a samurai sword. The project involves an innovative building technique. The roof was first built in the horizontal plane and then, using huge hinges, gradually turned upright.
