‘Circular’ timber construction in Sanu, Japan
In this project, wooden cabins are built at various locations in the countryside around Tokyo that offer busy city-dwellers the chance to spend a few days in picturesque rural settings to either work undisturbed or simply relax. Potential customers can take out a subscription and then book stays at cabins at various locations that can be reached from Tokyo in a few hours or less.
Only domestically sourced timber was used in the construction of these SUNU cabins. The lifecycle of each cabin was considered in a holistic manner along the entire process of raw material procurement, construction, normal service and ultimate dismantling. The result is a ‘circular building’ that has a minimal environmental impact.
The ‘circular construction’ approach involves the creation of closed material cycles by using renewable raw materials and ensuring that the building components are themselves reusable in the future. In addition, the floor plans are kept flexible so that the building can be used for a range of purposes and for as long as possible.
Between late 2021 and summer 2022, fifty of these cabins have been built at seven different locations. A second project phase will see the construction of a further 81 cabins!
