The National Building Museum is creating a series of videos about DC’s “Great Green Places,” which combine transit, good streetcapes, parks, and a sense of community to create a welcoming and sustainable place to live. In the latest video, Office of Planning head Harriet Tregoning gives a tour of Columbia Heights, where historic row houses coexist with new condos and lively retail.
