Colonel John Cox House
Architectural History and Landscape Documentation
Washington, D.C.

Robinson & Associates was contracted by the National Trust for Historic Preservation to conduct a detailed investigation of the history and significance of the Colonel John Cox House, built in 1816-17 as the end unit of one of Georgetown’s most notable Federal townhouse rows. The house is highly significant for its ownership by three prominent families and for its exceptional architectural quality. Robinson & Associates, in conjunction with a historical architect, analyzed documentary and physical evidence to determine the social and physical history of the house and landscape. Historic photographs and maps, wills, an inventory dating to 1846, historic clippings files, census records, building permits, tax records, and other sources were used to compile a thorough history and analysis of the significance of the site. Research and documentation were used to inform the easements and conditions intended to govern the future use and treatment of the house.

Rosedale Estate
Washington, D.C.

Located in the Cleveland Park neighborhood of Washington, D.C., Rosedale stands as a rare 18th-century country residence that was listed in the National Register of Historic Places in 1973. Working with a landscape architecture firm, Robinson & Associates was charged by the Friends of Rosedale to amend the National Register listing to evaluate the 6.7 acres of land that comprises Rosedale’s historic landscape. This effort involved site investigations, review of existing documentation, research and documentation of the colonial-era landscape, and viewshed analysis. Another primary area of potential significance was a twentieth-century design overlay by noted landscape architect Charles Freeman Gillette. Additionally, the firm created an Existing Landscape Conditions report to increase the awareness and greater understanding of the site’s integrity and its features and to contribute to the Friends’ strong protective stance for the site.

The Sewall-Belmont House
Washington, D.C.

Robinson & Associates served as architectural historians on a team of architects, landscape architects, and engineers in the creation of a Historic Structure Report for the Sewell-Belmont House, a Federal-style house museum constructed ca. 1821. For the historical sections of the report, Robinson & Associates provided extensive documentation on the property’s development and use over time, including the major periods of construction and alterations. A historical narrative established a historic context and the house and ground’s significance. These sections were supplemented with descriptions of the significant features of the house, library, outbuildings, and landscape, and a compilation of historic photographs, period maps, and original drawings. The resulting report was used as a guide for future preservation, restoration, and rehabilitation of the house and grounds—and its continuing use as a house museum, educational facility, special events venue, and offices for the non-profit organization.
