Portland-based architect robert oshatz has a repertoire of unique projects located around the american west that hold a striking relationship to their natural surroundings. without exception, the 'wilkinson residence' is located on a steep slope in a heavily wooded area. the main living space is located higher up on the site residing amidst the tree canopies and accompanying wildlife and contains the kitchen, dining room, gathering area,built in fixtures and fireplace all within curving natural wood glulam beams, copper-plated frames and large glass walls that use the exterior foliage as a screen from direct sunlight and a large exterior deck that brings the user in direct contact with the tree-scape. the lower floor is characterized by cedar shingles that clad all surfaces, and contains three bedrooms and a bathroom. although it is a darker space, it is an area for privacy where views to the lower parts of the forest are framed by the deep fins between the windows. the material palette is not confined to either exterior or interior, as they often blend around and throughout the spaces creating a balanced structure in harmony with the natural surroundings.special attention was given to the sustainable features of the construction, plenty of ventilation and radiant heating maintain a comfortable internal temperature and air quality with low-E glass reflecting direct sunlight. the owner is at all times engulfed by the douglas firs, maples, and alders in a house consistent with the rhythms of the forest.
