About Villa A Weekend House
The villa overlooks a great view of the Pacific Ocean, not far from the town of Hayama, the birthplace of Japan's yachting culture. The villa's design is a sculptural form that is appropriate for this spectacular natural setting, with a vaulted roof and a series of arches that symbolize the image of the white, rippling sea. The curved arches of the CLT (cross-laminated timber) roof give a sense of spaciousness to the interior. The result is a villa that perfectly suits a laid-back lifestyle and provides a deep connection to the blue waters at its doorstep.
Press Kit
- Unique Properties
- The motif of the sea led us to search for a wooden structure that shared similarities with yachts and bridges. The curved lines of the vaulted roof give a sense of expansiveness to the interior space. The structure of the building is mainly reinforced concrete, but the roof is a wooden structure made of 7m x 900mm CLT assembled in a continuous arch shape. A characteristic large sash window in one corner of the living room gives the interior space an outdoor atmosphere when open.

- Production Technology
- The curved lines of the vaulted roof create the illusion of expansiveness in the interior space. While the building structure is mainly reinforced concrete, the roof is a wooden structure consisting of a series of continuous arches built with 7m×900mm cross-laminated timber panels—a design that required extremely precise planning and construction techniques to implement.
- Design Challenge
- Given the motif of the sea, we looked for a wooden structure that shared similarities with yachts and bridges.
Concrete was too heavy a material for the arched roof. Therefore, wood, a lightweight material, was chosen. However, wood by itself is weak as a structural material, so CLT was selected as a material that can realize a strong flat structure without beams.
The CLT is exposed in the rooms, contributing to a sense of openness that makes the occupants forget that they are indoors. - Project Duration
- The project started in December 2021 and finished in September 2023 in Yokosuka-city, Kanagawa prefecture.
- Operation Flow
- The result is an oceanfront villa with the amenities of a resort. A villa that perfectly suits a laid-back lifestyle and provides a deep connection to the blue waters at its doorstep.
- Research
- Survey Technique due to Sloping Site and Complex Shape The roof is sloped according to the slope of the site, and at the same time, the slope of the water gradient. In addition, due to the arch shape, the height of the roof differs in different parts of the roof. In this case, detailed 3D surveying was required to accurately set the relative height of the roof to the slope.
- Inspiration
- The villa overlooks a breathtaking view of the Pacific Ocean, not far from the town of Hayama, the birthplace of Japan's yachting culture. The design pursues a sculptural form befitting this stunning natural environment, symbolized by the large, vaulted roof and arches that evoke the image of the white, rippling sea. With the sea as a motif, we looked for a wooden structure that shared similarities with yachts and bridges, and the curves of the atrium roof made of CLT (cross laminated timber) give the interior space a sense of expansiveness.
