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.

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.

In 2017, that portion of Klingle Road became Klingle Valley Trail, reserved for hikers and bicyclists.

The Tregaron Conservancy refers to a 13 acre privately owned and managed historic woodland garden nature park in Northwest, Washington, D.C. and the nonprofit organization that manages it. It is an urban green space in Cleveland Park, bounded in the north by Macomb Stream and private residences, in the south and east by the Klingle Valley Trail which connects to Rock Creek Park, and to the west by the Washington International School and Twin Oaks estate. The conservancy is part of former Tregaron Estate, which was formerly part of the neighboring estate Twin Oaks. Landscape architect Ellen Biddle Shipman, designed a “wilderness garden, with streams and bridges and paths, and native plants and dappled sunshine" planted with specimens that mimic the natural surroundings. An heir to the estate recollected the grounds as "masses of daffodils in the spring and masses of azaleas and a little babbling brook and arched bridges under which I'm sure trolls lived." The cultural landscape report for Tregaron identified 6 distinct landscaping regions designed by Shipman: Cow Pasture & Oak - a meadow south of the Klingle stream, on the southeast corner of the conservancy Causeway & Pond Valley - containing Klingle stream running from Twin Oaks in the east into the lily pond and westward until it passes under the Klingle Valley Trail Drive and Meadows - the driveway running from Macomb to Klingle Valley roads and two adjacent meadows, a sloped one to the north and a flat one to the east Northeast Woodland, Stream and Trails - containing Macomb stream, forested hills, and paths connecting the Drive and Meadows to Causeway & Pond Valley Macomb Entry & Woodland Slope - wooded hill between the Macomb entrance and Hilltop, Gardens & House Hilltop, Gardens & House - on the west end of the property (Not part of the conservancy. Owned and managed by the Washington International School.) The conservancy hosts a diverse calendar of events, including tours of the conservancy, including ones focused on the site’s history, geology, birds, trees, as well as concerts, forrest bathing, Tai Chi, an Easter Egg hunt, and a discussion group for descendants of Holocaust survivors. The conservancy has formed volunteer partnerships with the Washington International School and a local gardening group.
