Makoto Koizumi, a director of Koizumi Studio, has designed a residence in an ideal location with a view of Mt. Fuji in Shizuoka Prefecture. The client, who is in his 40s, wanted a house for his future retirement, and it was planned to use as a training facility until then.

In consideration of the views of Mt Fuji, an L-shaped, single-story building with an attic was planned. The designer Koizumi said, "We built an observation deck on the first with the best view of Mt. Fuji and a picture window with benches on the ground floor."

Also, they created places inside and outside where multiple groups could spend time together because many people using the building as a training facility. Two outdoor decks were arranged, and a sink was built on the north deck to be used as a kitchen.

Based on the idea that people could sit and relax if there were steps, they created several bench-height steps around the deck and the dirt floor. The unique deck with a square pit in the centre allows people to sit around it or placed a bonfire stand in the hole. For the exterior walls, the designers used custom-made 'Yaki-sugi'(kown as Shou-Sugi-Ban) charred timber. Yakisugi is a traditional Japanese method of burning and carbonizing the surface of Japanese cedar to improve its durability.

They also said they visit the site once every 10 days during construction. "Each craftsman has their own way, so we need to ask the carpenter to find a better way. Conversations with the craftsmen build trust, and they will work on it carefully and make it better. That is why we only design houses where we can visit," he said.

The house features many unique details by Koizumi, an experienced furniture designer, such as the sofa space at the end of the corridor, the sensitive shoji screens, and the door of the toilet.
