This rammed earth dwelling was designed with the energy-conserving strategy of thermal mass walls on the west, south, and east exposures. Framed walls with polycarbonate cladding were used in the protected exposures (north and under the carport roof). One wall of the living room slides open, allowing interior space to extend out under the carport for social occasions. Project architects: John Folan and Mary Hardin. Photos by Liam Frederick.
