Since 1983, Greenstone has been building new homes and communities throughout the Inland Northwest. As one of the area's leading builders, Greenstone is 100% committed to building homes that meet Energy Star and Inland Northwest Built Green certification. Greenstone is one of the only builders in the Spokane area that uses advanced framing technology. They also use low-emission paints and carpets to improve air quality in every home. As well, Greenstone uses durable materials to reduce maintenance and replacement costs. With sealed ductwork Greenstone eliminates holes and cracks in heating and cooling ducts to reduce drafts, dust, and noise.
