A new prototype of urban housing – A home for a young couple and their two children in Toyota City, Aichi Prefecture. Located on a long and narrow site from east to west, there is heavy traffic on the west side of the road, closely adjacent buildings on the north and south sides with a wide opening to the sky to the southeast on the second floor . The mass is a compact box with a facade of 2 ken (3.6 m) x depth of 7.5 ken (13.6 m), 15 tsubo (50 m2) x 2 floors = 30 tsubo (100 m2) in total , with a height of about 6 m. The structure is divided into three levels. A large window on the southeast wall of the living room connects to the urban void.

The covered terrace along the street side of the dining room and kitchen has a mesh facade and translucent walls on the sides to allow full access to the changing light and wind while maintaining a moderate distance from the city. . To ensure comfort and energy efficiency throughout the year, the outer skin and mechanical equipment have been designed for comfort and energy efficiency. Within a limited budget, we have devised ways to ensure high performance with a combination of greatly reduced materials and low cost equipment.

We created a warm wood-filled space by eliminating interior finishes using exterior insulation and exposing the wood structure, base, piping and wiring. This allows residents to understand the structure of the building and to carry out repairs and modifications themselves. It is a proposal for a new prototype of urban housing in the era of the global environmental crisis, proposing a charming house open to the interior (family) and the exterior (city), full of light, of wind and natural materials, with less construction material and waste.

Achieving high earthquake resistance, comfortable thermal environment and healthy ground environment at low cost. By placing load-bearing walls with structural plywood and steel spacers at suitable intervals at both ends of each floor in the short direction, we have achieved high earthquake resistance performance (grade 3) while eliminating differences deformation in the bucket floor and suppressing deformation during wind pressure. , as well as spatial flexibility and transparency. The height of the three floors has been reduced to less than 6 m. The roof was constructed with fewer components, using 3.5″ square beams above exterior insulation and a folded roof over plinths and asphalt roofing.

This strategy simplified the roof framing and eliminated the need for rafters. By using high performance exterior insulation, window frames and eaves, the building achieved high envelope performance, with a UA value of 0.49 (ZEH+ standard) and an ηAC value of 2.2 (above energy saving standard). A comfortable thermal environment was achieved at a lower cost by designing ventilation routes and using fans and ducts to distribute hot/cold air from a single underfloor air conditioner to each area. In addition, the entire site, including the soil, has been improved by digging trenches and holes outside, burying organic materials and allowing water and air to move through. the ground in a way that is possible even for amateur builders.
