Cell Space Architects


This is a weekend bungalow where the eaves extend out, appropriate for rainy Karuizawa old town.
The plane is composed of obtuse angles of 120 degrees based on an isogrid like a honeycomb.
Compared to a right angle, a 120 degrees angle, creates a rich space that is free and open to people’s movements.
Some features are a large meandering living room and dining room, an entrance that is separated from the main hexagon, a long corridor with folded glass walls, a small curved toilet and an asymmetrical terrace that overhangs the garden. Inside the building hundreds of 120 degree angles are used in the structure from plane to fine detail. These form diverse spaces and sequences, linking the natural scenery and the building space.
