From rough - cut cyprus walls to bleached - oak floors and exposed structural fir , this so - called tree house by Bates Masi Architects certainly does surround residents with woods of all kinds in every possible way , from each vertical and horizontal wall and surface within the home to the exterior cladding and surrounding forest . Somehow the structure manages to maintain a degree of modernism through simple lines and volumes and minimalist detailing , despite the contrasting and lively weathered , worn and rusticated look of the wood that permeates the interior and exterior of this home . Similarly , a blend of cozy and contemporary color schemes , furniture , furnishings and fixtures makes the interior work as both a modern residence with a distinctly comfortable and traditional feel to it .
