This project is a vacation house built in Karuizawa, Nagano Prefecture, a prominent Japanese resort located on a plateau with an elevation of approximately 1,000 m.
Sloping in the southeast direction, the vast site has an east-west dimension of 120m and a north-south dimension of 80m. With no obstructions in the surrounding visual field, the site overlooks a continuous forest and a mountain range in the far distance with a height of 2,000 m.
For the space between sky and land, the linear design of the architecture consists of the utmost extension of two slabs (roof and floor). The length of the building is approximately 50m. The interior space is sensitively divided into owner space and guest space with an inside terrace that penetrates the linear direction of the building. Furthermore, in order to achieve a horizontally continuous space without columns, the roof utilizes a structure consisting of cantilevered steel-frame trusses sitting on scattered concrete boxes.
The proposed site plan includes extensive tree planting and the utilization of water from a mountain stream to create a 1,400 square meter pond and brook.
