This 2064 s.f.
residence is the second "Cast
Earth" home built in Austin. The 20" thick earthen walls,
built by the owner, make this home ideal for our hot climate.
The Design
Concept again utilizes the "one-room" concept to promote natural
daylighting and ventilation. In addition, three cupolas act as
thermal chimneys for the
family room and bedrooms, to draw hot air out of the home when the
owners open the windows.
The home has abundant green feautres, including stained concrete
floors, metal roof, wood windows, spray-foam insulation, and of course
the Cast Earth walls.
