Gray shingles, rather than clapboard, were employed on the exterior in keeping with local traditions. The wings contain various family rooms and the garage is treated as a stable. A formal garden with parterres is to the rear, as is a swimming pool. The designs of the octagonal garden and pool structures can be traced to Mount Vernon. The interior contains a mixture of features that are common to the twentieth century, including a media room, and there are large windows to the rear for light and for connections to the garden. Richard FitzGerald advised on the interior, resulting in a mixture of colonial- and Federal-era furnishings supple­mented with nineteenth-century American art. The hall con­tains a mural illustrating local Osterville history, painted by New York artist James Alan Smith. The floor has wide boards and hand-stenciled patterns derived, again, from the Federal period. Evoking the oriental connections of many Cape Cod ship captains of the Federal period, the dining room's walls are covered in a hand-painted Chinese-styled wallpaper. All of the house's front-facing windows have inte­rior shutters that fold back into recesses in the deep wall. The house is impressive but also reticent in the best Royal Barry Wills tradition.16
