Striking Green-roofed Earthwall 2 Residence is an Energy Efficient Groundscraper in Idaho

This striking <a href="http://inhabitat.com/green-roof/">green-roofed earth home</a> in Idaho is long and flat like the surrounding landscape of Squirrel, Idaho. An environmentally-responsive abode, Earthwall 2 was literally constructed out of the deep red soil on which it currently rests, ensuring a gentle, harmonious footprint. <a href="http://www.wardblakearchitects.com/projects.php?project_id=40&amp;ar=1">Ward+Blake Architects</a>, who have been featured before on Inhabitat, patented and implemented their own rammed earth technique for this charming energy-efficient home.

This gorgeous green home rests on the red soil of Squirrel, Idaho

Ward+Blake used rammed earth walls made with the soil used in construction

Long and flat, the house is topped with a sod roof

Reclaimed douglas fir was used for the soffits and ceilings and reclaimed stone was used for other architectural detailing

A ground source heat pump regulates interior temperatures, requiring minimum mechanical intervention to heat or cool the space

The rammed earth walls have high thermal massing

Daylight pours through the windows

The green roof provides further insulation

Warm and cozy despite its 5994 square feet footprint, the home was designed to have the smallest possible environmental impact
