We present Apartment 40, a minimalist concrete house with a balance between privacy and openness. The building concept, created by K2, seems to echo Bauhaus principles.
Apartment 40 Concrete House – Linear and Geometric Aspects

The house takes its name from the 40-meter exterior wall, Ukikabe, an architectural element that appears to float above the ground. Ukikabe stands 1.5 meters back from the front and shields the home from prying eyes. Meanwhile, the house is surrounded by seven-story concrete buildings.The site lies in Ehime Prefecture, near the Shimanami Kaido highway that connects Imabari with six islands in the Seto Inland Sea.
Concrete House with a Simple, Bright Interior

The massive, stable concrete construction is designed as a highly insulated flat-roofed building and stands for safety and longevity. The shape of the building creates different qualities within the open spaces.
The use of glass allows the living areas to harmonize with their surroundings

The interior is oriented inward and reflects the minimalist simplicity of traditional architecture. Inside, glass partitions shape the rooms. The living spaces face east or west. At the center is a large room that divides the house into two main parts. High ceilings and warm wood ceiling panels contribute to calm and well-being in this minimalist concrete house.
Seemingly simple

Individual rooms, such as the bedrooms, are oriented to the north. Maximum transparency in the northern part of the house supports the modern, open character of K2’s architectural concept and blurs the boundary between interior and exterior.
Ukikabe – an architectural element

In the southern part of the house is a mezzanine, with storage space below. The kitchen and dining room are upstairs. The concrete building includes a game room, courtyard and outdoor pool.
