First purchasers describe the process.
"Before excavating, Barry and I decided exactly where the LV Home would be built. We chose a knoll with southern exposure. We marked the trees that needed to come down and staked out the building's rough location with rebar. Since we wanted the LV Home to 'float' on the ground per Rocio's design, we were faced with a problem. The building site is on a hill with a 7-foot slope. We wanted to keep the natural landscape of the knoll undisturbed. So we chose to level the hill where the house will sit and terrace the remainder of the hill. This was a risky decision because we didn't know if the excavator would hit rock..and there's plenty of rock!"
