This Fallen Maples Home in Issaquah, Washington is nestled into a large forested site that takes environmental sensitivity to a new level:

Completed by Gelotte Hommas, this home manages to balance day lighting and heat loss thanks to several eco-friendly in-built features. The designer explains:
"Maple trees harvested from the site were milled to provide the material for all the door and window trim, the cabinets, and special finish carpentry such as screens, a bench facing the kitchen, and the fireplace mantel. The result is a home that is truly of the site, not merely on the site. With all primary living spaces on the main floor, there is a strong connection between the house and the site.  The great room features a soaring roof that opens to the trees that surround a small lawn area carefully sculpted within the forest.  This roof extends over a partial upper floor containing bedrooms and a study loft that overlooks the great room. This is a delightful family home that truly connected to its site, both physically and emotionally."
