Coates Design Architects have designed the Olympia Residence in Yelm, Washington. Settled on the rural plains of Washington state, Coates Architects constructed a 21st-century little house on the prairie. The Yelm residence proves that modern architecture and pristine nature are not mutually exclusive. Indoors and outdoors meld thanks to the extension of interior concrete flooring to an outdoor patio area; the natural birch and cedar interior echoes its wooded views; and a completely flat roof and horizontal profile resemble the flat prairie setting. The radiant floors are soycrete-stained concrete, natural ventilation and heat on-demand control the home environment, and all the lighting is CFL and LED.
