Daimyo 509 is a minimalist architecture project located in Fukuoka, Japan, designed by CASE-REAL. Daimyo is a commercial area located in the heart of Fukuoka city, and is a home to many clothing shops and restaurants along its narrow allies. In contrast to this, old houses still remain standing which create a distinct atmosphere of low and high level buildings co-existing. The task the designers were given by the client was to design a two floor structure for high quality tenants. They decided to approach this task with their experience from commercial space design, and to adapt this into the architectural volume, structure and facility planning.
The volume on the ground level was set back in order to created a space which separates the relationship of the alley from the building and preventing the entrance from directly facing the streets surrounding. The approach created by this set back continues to the staircase which connects to the upper floor. In addition the line of the stair circles the building creating its distinct exterior impression. The overall building was constructed based on a frame structure, but by having all its pillars enclosed in the depth of its walls. In general visible pillars in limited zoning are considered as restrictions to the tenant plans, but by successfully designing a structure which creates a flat space, they were able to maintain the freeness for the tenant planning. The outlet / inlets for some of the facilities including air supply and exhausts were accumulated on the rooftop. Expected piping routes were pre-arranged to prevent effects to the exterior even after the tenants move in.
