Green Roofed Grass Cave House in Yokohama

This green-roofed residence in Yokohama, Japan is a prime example of creativity driven by spacial limitations.  The Grass Cave House by Makiko Tsukada Architects is built into a small slice of property, a v-shaped lot with permanent structures on all sides.  The small, tight space left no room for a proper yard, so the architect placed the green spaces on the roof line– a series of terraces that extend from the central living spaces.  Thus, the name “grass cave” is entirely descriptive of the project– the interior spaces are like caverns beneath grass roofs that allow for peaceful, private relaxation on a “yard” this plot was not destined to feature.

The Green Roofed Grass Cave House in Yokohama comprises 97 square meters of space on its v-shaped lot.  Since the architect could not build “out”, they built “up”, using a varied split-level design that created rising forms with several exterior patches of green grass.  The interior spaces of the Grass Cave are black on all sides, with black-stained wood for walls, ceilings and floors.  The architect balanced the dark interior textures by bringing in plenty of exterior light through slatted windows that virtually line the entire interior.

Makiko Tsukada’s Grass Cave House was completed last year, a success in both green roof architecture and limited-space construction.  It has the feel of a treehouse to us, a playful and imaginative home design that rose to the challenge of its lot.
