The majority of the structure is FSC wood (including floor joists and roof trusses, OSB Dryguard FSC ect). Forest Stewardship Council (FSC) certification, which promotes ecologically respectful and socially beneficial forest management. Materials with low VOC emissions are used. The project promotes water based paints, low-VOC glue that meets LEED requirements, and furniture cabinets without added Urea-formaldehyde.
