Flat 40 by K2 Design

Flat 40 is a minimalist house located in Imabari City, Japan, designed by K2 Design. A seven-story apartment building towers on the south side of the property. The concern was how to block the line of vision from the apartment building and maintain privacy, while ensuring ample light and ventilation. In order to meet these requirements we designed a 40 meter concrete screen wall along the south side of the residence. Precise calculations were done for its size and structure. (22)

Flat 40 is a minimalist house located in Imabari City, Japan, designed by K2 Design. A seven-story apartment building towers on the south side of the property. The concern was how to block the line of vision from the apartment building and maintain privacy, while ensuring ample light and ventilation. In order to meet these requirements we designed a 40 meter concrete screen wall along the south side of the residence. Precise calculations were done for its size and structure.

The structural feature we adopted is ukikabe, a floating screen wall, which is suspended above the ground 1.5 meters away from the exterior of the residence. An important feature is that it is a concrete wall. The purpose in choosing such heavy material was that it was imperative the wall rest in balance with the building architecturally. The one-story design was realized in consideration of the structural requirements of the wall and the habitability of the house. The ukikabe solves a number of issues. It successfully obstructs the view from any floor of the neighboring apartment building, yet from inside the residence, one can see the feet of those approaching the property.
