100％　Natural materials

The Local House series aims to use natural materials and return to the earth.

Around 2000, after my niece suffered from sick building syndrome, we thoroughly researched whether we could build a house using only natural materials so that she could live in a chemical-free environment.

This building was designed to be safe and comfortable, with no chemicals, not even 0.0 PPM.

We build our buildings using materials from as close to home as possible. We aim to build within a 50km radius.

By using wood processed at a local sawmill from local forests, we can reduce transportation costs and make our buildings blend in with the local environment and have less distortion.

Floor: An air insulation layer is installed, and the natural oil finish gives it a gentle texture.

Walls: By mixing local soil with sea ash plaster, we can also expect a purification effect of environmental viruses.

Ceiling: The finish is made of natural materials, and the interior is made of air layers and natural soil to enhance insulation and heat retention.
