― Between the Moving and the Unmoving ―
Around 4,000 years ago, lava flowing from Mount Omuro covered the undulating terrain, reaching Sagami Bay and creating a plateau. The vegetation that grew on the plateau underwent succession, and the area is now home to a residential community that enjoys moderate sunlight and sea views. Living here means placing oneself along the extended line of such long-term geological shifts, with architecture representing the temporary dropping of anchor upon its surface. It is an experiment born of the interplay between the 'moving' and the 'immovable', a device for sensing nature's order with delicacy.
The site is part of a holiday home development established 66 years ago — a forest of dense Japanese cypress trees that had never been built upon. It offered a picturesque vista where nearby trees overlapped with the distant Izu Islands, and dappled sunlight and breezes provided natural comfort. The architecture aims to coexist quietly without disrupting the order of the existing terrain.
Initially, various forms that aligned with the layout of the trees were considered, but ultimately, the decision was made to introduce a distinct geometry into nature. Carving into the volume resulted in the creation of a simple rectangular house. This rectangle possesses the order of the traditional Japanese measurement system and inherits the wisdom of Japanese architecture, while also symbolising immovable construction.
The main floor is elevated approximately two metres above ground level to avoid the tree canopy while offering the most beautiful view of the horizon. The floor extends outwards as a terrace, supported by slender columns spaced 4.4 metres apart. This columnar group echoes the verticality of the cypress trees and blends into the forest, creating a sense of both floating and groundedness.
The interior is made up of wood fibre cement boards and resin mortar. By meticulously integrating the utilities, a serene and substantial space has been created. Within this dual relationship of openness to the sea and security from the forest, the building eventually seems to be swallowed by the landscape.
Although architecture is immobile, in the face of nature it is merely temporary. It is in this interplay between the 'moving' and the 'immovable' that the ephemeral beauty of architecture emerges, capable of emotional transformation without changing form.
