東広島の家 House of Higashi-Hiroshima

The site exists in a residential complex on high ground in Higashi-Hiroshima. A uniform rectangular site was selected as the site for this project. Although the site is generally a part of a residential complex that can be found anywhere, we proceeded with the plan considering the surrounding environment and adjacent residences as characteristics of the site.

First, the walls and openings were arranged according to the site conditions. By doing so, we thought we could derive a clear architectural style and characteristics that are unique to the site. In this project, we tried to create a design that would take advantage of the expression and characteristics of the building materials. The main structure of the building is made of concrete.

The main structure of the building is made of concrete, while the interior space is made of wood, and by incorporating a natural wooden box into the inorganic concrete box and providing an intermediate area as part of the living space, we were able to create a new lifestyle and increase the effectiveness of cost performance. By providing this intermediate area as part of the living space, we expect to enhance a new style of living and cost-effectiveness.

This CASE/STUDY/HOUSE is a simple concrete frame. The CASE・STUDY・HOUSE simplifies the concrete frame and performs rational structural analysis. The reason for this is that by combining a simple concrete structure with a simple wooden frame, we tried to find a unique way of structuring space that is different from the conventional single structure.

Although ready-built houses and prefabricated houses are also fine houses, the "TSUKURIYA" is not the same as the "TSUGURIYA" in this PROJECT. In this project, based on the concept of "TSUKURIYA," all the members involved in the building process are involved in the construction process. In this project, based on the concept of "TSUKURIYA," we thought that the "spirit" and "skills" of all the craftsmen involved in the construction, as well as the careful and solid construction of the entire building, are important social themes and essential for "house building" in today's society.

This is one of the reasons why we chose a unique construction method that combines the labor-intensive concrete and wooden frame construction methods, and aimed to create a building that makes the most of its materials. The completed CASE/STUDY/HOUSE is now called "CASE/STUDY/HOUSE. We hope that the completed CASE・STUDY・HOUSE will fulfill its role as a "handmade house built with architects" and share social values with everyone.
