Architecture

Structure

A multi-generational house built on the site of the family’s former home. After living abroad for 45 years and moving through 20 different residences, a couple finally returned to Tokyo to settle alongside their 100-year-old mother.

Like the thinning of a forest, our approach was to carve out small clearings along neighbouring properties by indenting the building’s form, softening the impact of growing urban density. These slight recesses welcome light to the ground, breezes through the site, and a sense of spaciousness within a modest urban fabric.

Inversely, from within, these indentations are experienced as spatial swellings. Curved walls obscure direct sightlines, allowing residents to maintain a comfortable degree of separation and to inhabit personal spaces within an open-plan environment.

One challenge was managing the family’s extensive belongings, rich with memories, accumulated over time. The Japanese proverb, “If you want to hide a tree, hide it in the forest,” guided our approach to integrate these items seamlessly into the environment. The fan-shaped structure of branch-like columns and beams creates a soft perimeter with 105mm-wide timber undulations, scaling the architecture down to a more intimate dimension of everyday objects. The textured surfaces visually soften the clutter, allowing items to recede into the background. This detailing also enhances timber’s inherent qualities — modulating humidity, absorbing sound, and releasing its characteristic aroma. The interplay of indents and protrusions at varying scales helps regulate both environmental and sensorial comfort, inside and out.
