It is built from simple, basic materials; Lukas writes:

The materials chosen for construction are readily available through local distributors. We favour solid materials – avoiding composites, laminates and their associated adhesives. We have chosen predominantly SPF BC lumber, unpainted galvalume steel, and concrete. Our only composite material will be plywood, which will be used for cladding, cabinetry and exterior wall sheathing. The use of solid materials improves indoor air quality and increases the lifespan of the building. Solid materials tend to “age with grace”, acquiring a patina of use over time that adds character. Composite materials tend to chip, fade and delaminate over time, requiring replacement and renovation.
