The new home office addition was built beneath the pad of the Zen-like garden, which began with the excavation of 80 truckloads of dirt in front of the retaining wall.
The adjacent pool area was left completely intact, with a supporting column incorporated into the design, and a window cut out of the existing retaining wall. A new concrete wall was added that also included the entrance.
