Located just past the iconic neighboring cherry blossom tree-lined avenue is an approximately 75 sqm site that possesses an irregular shape – a unique hybrid of a rhombus and a circular arc. Limited not only by strict building codes and regulations, there were also various height restrictions with which to contend.
In order to design a three-story building within these limitations, a split-level floor structure emerged, resulting in a complex spatial structure with eight floors that connect in a continuous spiral.
From the outset, the client wanted to use “real materials” rather than spaces covered with superficial finishes.
With wood, stone, and steel as the primary materials, the interior was designed to enhance their materiality to allow an appreciation for the changes over time. Also as a strategy to make the most use the limited space, instead of creating a standard stairwell, steps were designed to be used as a chair or bench or as a surface for AV equipment, blending the residential spaces.
As a design for the home of a young couple, the focus was on ease in maintenance and creating a space that would become loved and cared for by the family for many years to come.
