"Park Wellstate" by Mitsui Fudosan Residential is a senior service residence that aims to allow mature, active seniors with diverse values to live a new stage of life in a more free and rich way, in their own way. "Park Wellstate Kamogawa", the second property following "Park Wellstate Hamadayama", was built in Kamogawa City, Chiba Prefecture, and is a 22-story building with approximately 470 units. It is a high-value-added facility that has partnered with the medical corporation that runs Kameda General Hospital in the same city and has leisure functions within the facility. Our company was in charge of the lobby and reception in the common area, the promenade, the club lounge, the restaurant, etc. [Social issues / Customer issues / Requests] The land where this project was built, Kamogawa, was originally a hilly area covered with forests with a rich ecosystem. In the 1990s, it was used as a quarry, and the trees were cut down, leaving the rock surface exposed, and the natural environment was lost. From the viewpoint that the natural environment is the foundation of a healthy and rich life and improves the quality of life for seniors, the aim was to create a home where the seniors who live there can spend a rich time and live a rich life while restoring nature. [Solution] To solve the problem, the interior space was finished with light-toned white sycamore veneer to create a warm shared space. The height of the built-in washbasin was set lower than usual to suit the seniors, and the corners and edges were chamfered with a rounded edge. The floor finishing was made with stone veneer, carpet, and narrow joint widths to avoid steps on the flooring, and concept design was made to be safe and friendly for seniors. The artwork was selected based on the former quarry site and the Kamo River, and local crushed stone was used, and artwork expressing the charm of the Kamo River was installed to allow the residents to feel the local climate and culture. <Our project members> [Sales and project management] Naoki Murata [design, layout] Common area concept design and supervision: Michio Matsuzaki / Artwork coordination: Misa Sanjoba, Wataru Tajiri [Production and construction] Masato Takeuchi, Shusuke Hoshino, Keiichi Yamazaki, Shogo Yasunaga
