Tilden Gardens is a six-building apartment complex in the Cleveland Park neighborhood of Washington, DC.

[1] All six buildings center on a three-acre multilevel garden[3] that has been described as the best of its kind in Washington, DC.

[4][2] The Tilden Gardens units were originally planned in 1927, as cooperatives (co-ops).

By 1939, it became possible for owners to sell apartments again, and the later four buildings were incorporated as a single "Tilden Gardens" co-op.

The resulting structure (still known as the F/G building) ended up with the oddity of two identical front doors a few feet apart.
