Yao Tree Project




The Steel six-story tenant building is in Yao City, Osaka. Since the Coronavirus pandemic, we have considered the availability of natural ventilation to be an important factor that has an impact on occupancy rates. It has the theme of “A building where the breezy wind blow”, we created to realize feasibility of the business and rational cost balance, and to appropriate for the commercial area in front of the station with a lot of traffic.

To take advantage of the corner lot, and tenants on each floor are arranged so that they face the road with good environmental conditions. The necessary functions of the building consolidate to the back side of the building in a rational plan to maximize the area used on each floor. Each tenant has a balcony to create a relaxation space and to feel nature even indoors, and the large openings enable efficient natural ventilation. In addition, it has high safety features such as a temporary evacuation site in case of fire and a two-directional evacuation route.
Seasonal plants on the randomly arranged balconies add color to the city, and the exterior wrapped in wooden lattice gives an organic and soft impression like a "big tree”.We hope that the building keeps an ability to attract customers and to become a landmark in front of Yao Station.
