Woodley is a Federal-style hilltop house in Washington, D.C., constructed in 1801. It has served as the home to Grover Cleveland, Martin Van Buren, and Henry L. Stimson, and is now the home of the Maret School. When originally built, it was based on the Woodley Lodge in Reading, England. Coincidentally, given the mansion's original site, the word "Woodley" means "clearing in the woods." A Maret School-based organization called the Woodley Society was created in 1994 to study its history. Since then, it has become an association of students, faculty, and alumni, which has conducted research in a number of archives and libraries in the Greater Metropolitan Washington area and beyond. In 2008, the head of the group, historian Allerton Kilborne, published a book about Woodley. The group's podcast, Echoes of Woodley, is available on Spotify and showcases stories surrounding the mansion.

Park & Shop, also known as Sam's Park and Shop, in the Cleveland Park neighborhood of Washington, D.C., was one of the first neighborhood shopping centers (or strip malls). It opened in 1930 with 11 tenants and was anchored by two grocery stores: an A&P and a Piggly Wiggly. The center is still in operation, currently anchored by Target. It was built in an L shape with dedicated parking space for shoppers in the front, a novelty at the time. This stood in contrast to the limited availability and harried experience of street parking in front of stores lining busy streets. The original developer was Shannon & Luchs and the architect was Arthur B. Heaton. Stores mentioned in a 1930 ad were: The center still exists, anchored by a Target store. It is considered a model or "template" for future such neighborhood centers, or even "a pioneering example of strip-mall architecture", and for that reason has been subject to historic preservation efforts. It was sold in 2020 to Asana Partners for $39 million.

The Kennedy–Warren is a historic eleven-story apartment house in Washington, D.C. It is located at 3131–3133 Connecticut Avenue, N.W. between the Cleveland Park and Woodley Park neighborhoods. The Art Deco building overlooks the National Zoological Park and Klingle Valley Park, which is near the Art Deco Klingle Valley Bridge. The original main building was built between 1930 and 1931 with 210 apartments. The plans of its architect, Joseph Younger, called for a northeast wing and a south wing as well, but construction of these was stopped because of the onset of the Great Depression. The northeast wing was later built in 1935 with 107 additional apartments, as economic conditions improved in Washington. And the B. F. Saul Company, owner of the building since 1935, added the south wing between 2002 and 2004. The architect of the northeast wing was Alexander H. Sonneman, and of the south wing was Hartman-Cox. The current total number of apartments, ranging from efficiencies to three-bedroom units, is 425. The Kennedy–Warren is considered the largest and best example of an Art Deco building in Washington. In 1989, the building was listed as a District of Columbia Historic Landmark, and in 1994 it was added to the National Register of Historic Places. The newer south wing won numerous awards for the quality of its architecture, and for attention to historical detail, including the 2005 Award of Excellence for Historic Resources by the American Institute of Architects.
