The Ureshino-City project in Japan's Kyushu Region faced significant challenges due to its location in a flood-prone, low-lying delta between the Shiota and Urata Rivers. The area experiences flooding approximately every decade, particularly when heavy rain coincides with high tide. The geography became even more critical after the Great East Japan Earthquake in 2011, which caused devastating floods and loss of life. This tragedy heightened the awareness of disaster prevention for the SUEP. team. The challenge was to design a cultural center and junior high school that could withstand potential flooding while also addressing the area's declining population. The project needed to incorporate disaster prevention measures and energy-efficient solutions to create a safe and sustainable environment for the community.

To address the challenges of the Ureshino-City project, SUEP. incorporated disaster prevention and energy-saving ideas into their design. They used SimTread, a plug-in for Vectorworks Architect software, to model pedestrian evacuation flows, ensuring safe evacuation routes in case of flooding. The buildings were designed with raised floors and ample green space to absorb flood damage. The cultural center and junior high school were strategically placed on neighboring sites, with a shopping center and proposed plaza in between. The cultural center features a 1,000-person arena, a 500-person cultural hall, and several multipurpose rooms, while the junior high school includes 12 regular classrooms, 10 special purpose classrooms, a library, gymnasium, and martial arts gym. Energy-efficient features include a steel structural frame, concrete walls, and a natural air-conditioning system. The school's roofline forms a tree-like canopy to maximize shade and reduce the need for air conditioning. SUEP. also drew inspiration from traditional architectural designs in the area, transforming them into modern, organic structures that fit seamlessly into the landscape.
