MORI-HAKO by Temporary Office

Inspired by the delicate art of a Japanese gift box like Kiribako or Oribako, where each layer is thoughtfully designed to build anticipation and surprise, this retreat house gradually reveals itself, much like the careful unwrapping of nature’s gift. Situated within the tranquil, dense forest of Kitakaruizawa, the design emerges as a respectful offering to its surroundings, with each space representing a new discovery within the natural environment.

The building is seamlessly embedded within the rocky topography of the forest, nestling into the landscape and utilizing the natural contours to shape the living spaces.

The roof appears to float above the terrain, gently revealing the land below, with clean, minimal lines and materials that reflect the quiet elegance of the surrounding forest. With the folding of the roof on the inner courtyard, it also mirrors the vernacular language of Japanese courtyard houses. Just like the durability of paulonia wood for kiribako, roof slate is choosen for the main enclosure, a material that’s equally durable across all seasons and harmonizes with the rocky terrain.

The overall structure is synergistic with the landscape. The natural rocks on site also serve as structural support for the roof, allowing the roof feel lighter as it touches lightly on strategic points.

The proportion of each space seamlessly integrates with the existing terrain, respecting the natural landscape by creating four distinct quadrants between the gaps of the rocks, resulting in 4 quadrants. Each quadrant offers a unique experience, utilizing the natural contours to define areas for living, resting, cleansing, and entry. These spaces are interwoven with outdoor and indoor courtyards, allowing nature to penetrate every part of the house, dissolving the boundary between inside and outside. Playing off the natural cascading nature of the ground, the strategic placement of the bathing area on the lower point allows for natural flow of purified water beneath the soil to be used in the tub.
