Architecturally, the house is of particular interest because its basic objective of facilitating an indoor-outdoor style of living is achieved with simple, open lines and harmonious materials.[101] Set upon a concrete slab, the wooden walls of the house are overlaid with wooden beams placed so as to intersect and create the appearance of squares and rectangular modules on the ceiling. A flat wooden deck roof rests on these beams. No prefabricated units were utilized in the construction of the house, and all pieces were individually specified, cut, and fitted together. The architect for the Tobey House was David Condon, AIA, of Keyes, Lethbridge & Condon, Washington, D.C. The landscape architect was Eric Paepcke of Washington, D.C. Interior design was done by Top Recker and Patricia Holsaert. Construction was performed by Hayes Brothers of Herndon, Virginia (figures 14 and 15). EXTERIOR FEATURES. The overall dimensions of the house are 70 by 25 feet; the carport measures 11 by 21 feet. Exterior walls are gray stained cypress, laid on horizontally in ship-lap style, with white trim. Full-length glass panels serve as walls in the section of the house called "the gallery," facing the terrace on the east side of the house. The fountain pool in the east side terrace measures 6 by 13 feet. The pool water does not recirculate but is piped from the house water supply and can be controlled by a faucet. ENCLOSURES. A wooden post and rail ranch fence encloses the field where the house is located. LANDSCAPING. Pine and plane trees are planted for shade near the house and screening from the highway on the west side. Wisteria is planted for the trellis over the terrace on the west side of the house to shield it from the afternoon sun. In the immediate vicinity of the house, vinca minor (periwinkle) is used as ground cover. INTERIOR FEATURES. The Tobey House contains 2,062 square feet of floor space. Room arrangements for the original structure and following the addition in 1957 are shown in figure 15. Interior walls are of vertical cypress paneling, and floors are wooden parquet. Ceilings have exposed beam and plank construction. Interior features when Mrs. Tobey was in residence included wood carvings from a Scandinavian sailing ship salvaged when it sank off the New England Coast. Woodburning fireplaces are located in the living room of the original portion of the house (now used as a study) and the living room of the 1957 addition. The house is centrally heated with radiant heat from the floor. No central air conditioning was provided in the original portion; but, when the addition was built in 1957, central air conditioning was provided for it and ducts were extended into the living room of the original portion. Window air-conditioning units were installed in the bedrooms. II. THE BARN
