Green Stamp Karuizawa Dormitory Shoukan

Shoukan was originally part of the residence of Count Abe, the former lord of the Fukuyama domain, built in Nishikatamachi, Hongo Ward, Tokyo in 1892. It was relocated to Karuizawa in 1971 by Tokio Kasuga, founder of Green Stamp Co., Ltd., and restored. It has been used as a memorial hall for the Green Stamp Karuizawa dormitory.
In 2020, we renovated Shoyukan as well as the new Annex to serve as a retreat facility for both Green Stamp Co., Ltd. and Kenedix, Inc.
We were responsible for the design and interior administration of the Shoyukan renovation, including seismic retrofitting, as well as the FF&E installation work for the entire facility.

[Social Issues/Customer Issues/Requests]
Since the original relocation, various extensions and reconstructions have been carried out, and the connection with the annex was made only at the point of the corridor, and it was structurally burdened and subsidence was seen.
Due to the aging of the facility as a whole, and because of the climate of Karuizawa, it is difficult to use the Shou-kan in winter. It was thought that I would like to refurbish it while leaving the vestige of the old as much as possible.

【solution】
Based on the research conducted by Shoukan, we restored the building to the simple form it had when it was relocated as much as possible. The courtyard faces the annex, giving the facility a sense of unity.
While respecting the design of the time as much as possible, we aimed to extend the period of use, including winter, by installing heat insulation and air conditioning equipment in invisible parts. Floor heating was installed, flooring was added, and the walls added for earthquake resistance expressed the original walls, fittings, and the image of the time, and the upper half of the space preserved the design of the time as much as possible.
