This contemporary design incorporates the natural slope of the site with passive solar strategies to minimize heat loss/gain.  Thermal mass walls strategically placed throughout the house help to reduce large temperature swings indoors while also serving as guides to divide living spaces.  Large window walls are shaded in the summer, but in the winter allow warmth to enter the house to reduce heating costs.  The residence features a home theater, fitness center, pool and cabana, and two guest suites.
