In this major addition, a two story master suite overlooks an in-ground swimming pool and forests to the west. An arcade along the downstairs western edge leads to the grotto, a circular open-air room clad in stone.

Its subterranean character heightened by a heavy beam-work ceiling and large arched openings onto the pool deck. Above the grotto is a circular sitting area off the master bedroom. Bow windows frame sunset and garden views to the north and west.
