Amakusa City Hall

Amakusa City A low-rise government building of approximately 10,000 square meters was planned. To meet the diverse needs of citizens, staff, and council members, we proposed “three types of floors” featuring distinct spatial designs.For each floor, we selected the optimal systems for design, structure, and facilities—such as reinforced concrete flat slabs and underfloor air conditioning; column capitals and grid lighting; and wooden roofs with natural lighting and ventilation.The large, regular-shaped floor area of approximately 700 tsubo ensures flexibility by concentrating vertical circulation, private offices, seismic walls, and utility spaces in the perimeter “outer space.”
