It was listed on the District of Columbia Inventory of Historic Sites and the National Register of Historic Places in 2010 as The Keystone.

The building was designed by Robert O. Sholz in the Art Deco style and completed in 1931. It is a twelve-story building that was formerly known as The Keystone apartment building. It was acquired by the university and dedicated on February 15, 1971 as the University Clinic, or Burns Clinic. It was named in honor of H.B. Burns, the deceased brother of Jacob Burns.
