92 square foot SIP panel, modular, backyard office. Shou-Sugi-Ban wood siding and Monotread wall sheathing. Our signature interior surface, Monotread is a durable, seamless, sustainable material used on floors, walls and ceilings. Milled from OSB (Oriented Strand Board), Monotread is produced from fast-growing, underutilized, inexpensive wood species grown in carefully managed forests. The combination of wood chips allows a unique, monolithic presentation allowing various applications. Photography by Blake Gordon and Lisa Hause
