Hubert H. Humphrey Green Plaza Feasibility Study

Washington DC

Annapolis Landscape Architects joined the OLBN Architects design team in developing the Green Plaza Feasibility Study for the Hubert H. Humphrey Building was to mitigate urban stormwater runoff. The historic minimalist form of the architecture and site are from the 1970s are key elements to preserve during the process. Open space is mostly on-structure requiring a green roof to absorb runoff. This was configured in panels to compliment the site layout and striking plaza features, including a large "ziggurat" (paving structure) and sculpture.
