The client's family living in Tokyo started planning a villa as a base to spend weekends on the Boso Peninsula, which is rich in nature, and enjoy their favorite pool, sea, fruit cultivation, and cuisine made with Boso seafood with close friends.

The site is built in a terraced manner on a hilly area, and is surrounded by forests on the east, south, and west, and is connected to a road with little traffic on the north side. For clients who like to enjoy time and meals outdoors, we designed the space to center around a spacious outdoor living room with a roof facing the pool, and created a bow-shaped floor plan that offers views of the forest from each room.

When you open the entrance door and enter the hall, you can see the outdoor living room and pool view from the large window. The outdoor living room is approximately 50 square meters and can comfortably accommodate a dining set and sofa. It can be used in conjunction with the pool, and is planned to accommodate meals and parties for large groups. Also it has its own kitchen and storage space.

The characteristic bow-shaped gable roof and the exterior wall on the gable side are made of galvalume steel with vertical seam roof, and the exterior wall, which is not exposed to rain, is made of reinforced cement siding. For the roof and exterior walls, we use a ventilation construction method and use roof waterproofing and moisture-permeable waterproof sheets with heat-insulating properties. The eaves on the south side are 1.4 meters long and are designed to block sunlight in the summer and allow sunlight to penetrate deep into the interior in the winter.

Ensures insulation performance equivalent to insulation performance grade 4. We use high-performance rigid polyurethane form of 120mm for the roof and 60mm for the exterior walls. The opening uses an aluminum resin composite sash and double glass.
