This modern 3000 square feet suburban residence is located near Seattle. An openness, close connection to nature and fun are things that define the house’s design. It incorporates an eclectic yet refined mix of materials into playful and light-filled spaces. Besides that the materials are also those that architects use in contemporary house construction: concrete, steel, plaster and wood. The main part of the house has two storeys with blackened steel panels and an arched metal roof. Inside the structure, heavy timber meets a cement-based walls coated with veneer plaster. The house is heated with hydronic coils in the floors and is cooled passively through locally manufactured windows, doors and ceiling fans. source from
