In all, five years were devoted to completing the building, grading and landscaping of the 50-acre tract. The building rests on a solid concrete foundation with spread footing courses. The entire wall surfaces are of rock face, blue Vermont marble laid in broken Ashlar pattern and trimmed throughout with tool-finished white Vermont marble, each piece of trim being numbered. Walls above ground are a minimum of 13 inches thick. The maximum thickness of walls below ground is three and one-half feet.
All exterior woodwork is of clear white pine and cypress without knot or blemish.
All window openings are glazed with heavy plate glass. Back of the main parapet walls, the loggia and outside of the main enclosure is a terraced space of 3,300 square feet, not including the porte cochere, admirably adapted to outdoor parties or for rest and recreation. The loggia on the west, of 500 square feet, is glass enclosed and storm protected. Viewed from different angles, there is the same majestic harmony of detail and assembly. From the east and north, the towers, turrets, parapets, machiolations and battlements tell the story of medieval days.
