Carderock Springs Historic District
Bethesda, Montgomery County
Developed by Edmund J. Bennett and designed by Keys, Lethbridge, and Congdon between 1962 and 1966, Carderock Springs is a subdivision of 275 modernist houses located northwest of Bethesda. Typical of Bennett/KLC subdivisions, Carderock Springs was planned to take full advantage of the existing landscape and topography, with curvilinear streets and cul-de-sacs serving wooded, sloping lots. Houses within Carderock Springs represent a range of models suited to varying site conditions, unified by a consistent design aesthetic to create Bennett’s goal of a “visual community.” The majority of properties within the Carderock Springs Historic District retain a high degree of integrity, and contribute to the significance of the district. Properties will contribute to the significance of the district if they retain integrity to clearly identify them as representative examples of their type/model, and if they are historically associated with the theme of Bennett/KLC collaboration which is central to the historic context of the district. A few properties have been altered to such a degree that they no longer so contribute. Carderock Springs also features a clubhouse and pool complex as an original amenity to the community.
The Carderock Springs Historic District is historically significant as an example of a type of residential development which resulted from the collaborative efforts of builder Edmund J. Bennett and architects Keys, Lethbridge, and Congdon in the suburbs of Washington, D.C. The Bennett/KLC collaboration received substantial recognition in the popular and professional press in its day, as outstanding exponents of “Situated Modernism.” This recognition enables Carderock Springs, which was developed between 1962 and 1967, to meet the standard of exceptional significance, despite its being fewer than 50 years in age.
