Our Works



  • Residence T renovation(Koga-shi, Fukuoka prefecture)

    design : Arch-staff Design Studio
    construction : Sumaikoubou

    It was just 100 years after this house was built, that we were asked to rebuild the house. The concept given by the customer was "the next 100 years".
    After the new building, this house was repeatedly expanded and remodeled, so many parts that were not consistent were found. As a result, we spent a lot of time to reinforce and organize the structure, and the construction period took over a year and a half. In this way, a house in which the customer will live the next 100 years is completed.

  • Takiguchi residence Old farmhouse renovation(Munakata-shi, Fukuoka prefecture)

    design & construction : Sumaikoubou

    The farmhouse, characterized with wide earth floor and continuous reception rooms, consists of two parts, one built 130 years ago, the other built 80 years ago. Since the underfloor was hardly corroded by insects damage and high humidity, the various structual repairing was needed for the old house. Some pillers were replaced, some were repaired by root succession, and some beams were replaced. During the renovation, many carpentry workshops were held in the place, and lots of the attendants got the opportunity to learn about traditional wooden building. The farmhouse belongs to a master carpenter, Takiguchi, in Sumaikoubou.
