Seizan Golf Course in Karuizawa is planning a renewal project that includes reconstruction of the clubhouse, which will take several years. The first step was to renovate the existing building (former ’ Asamatei’) so that it can be used as a temporary clubhouse. This building not only functions as a clubhouse, but also as a restaurant open to the public. Despite the renovation, the main concept was to design a warm and open interior space that foreshadows the wonderful new clubhouse. To minimize material waste during demolition, paper tubes made of recycled paper were used for walls and ceilings to create an organic space with a wood-like warmth.
