Visually, you can’t get a house much greener than one with a tree growing out of its base.  Environmentally, the Tree House by Standard Architecture is a green achievement as well.  The Tree House features a passive solar design, a reclaimed wood and concrete structure and a spacious interior with natural wood accents.  This home has been built on a Los Angeles hill ready for a green minded entertainment type to call this their own.  [standard via archdaily]
