A series of gray-green ceramic tile hipped roofs with broad overhanging eaves distinguish this stuccoed single-story, reinforced-concrete structure. Decorative masonry grilles with green backgrounds, conspicuous copper drain spouts, and the lava-rock entrance to the subterranean cart barn lend Hawaiian notes. The formality of the simple, clean-lined design and the spacious foyer's skylit ceiling is balanced by the overall openness of the building and its adjoining reflecting pool. The green granite floor nicely echoes the green of the roofs.
