Located along Independence Avenue SW from th to th street, the roughly -acre site includes the Castle, the Arts and Industries Building, the Freer Gallery, and the Hirshhorn Museum and Sculpture Garden – all individually listed or eligible for listing on the National Register of Historic Places – and the mostly subterranean Quadrangle Building which is home to the National Museum of African Art, the Sackler Gallery of Art and the S. Dillon Ripley Center.

By using a clover structure in organizing the residential program each patient’s room is oriented toward its own part of the landscape &#; two sets of rooms facing the lake, and one set of rooms facing the surrounding hills. That way the intimate living program has been folded into the landscape being on a level with the lake. Between the functions emerges a new collective space that is embraced by offices and bed units and populated by small patios.

Structurally, the pavilion was a giant self-supporting tubular steel truss, similar to the hull of a steel ship. The external façade structure was the buildings most efficient element. The perforation holes let in daylight and created natural ventilation. It was the only pavilion out of + that did not use mechanical cooling. Due to the structural performance of the truss, the degree of perforation varied with the structural stress along the façade.

At ground level, the lifted mass provides nearly % of the site devoted to public realm including two new, generous publicly accessible spaces linked together by the building&#;s lobby. At the north a new Bankside Square is created adjacent to the Grade II listed Anchor Pub, enhancing its setting. At the west, in conjunction with the neighboring Former Financial Times Building, a centralized, tranquil Pocket Park is created in association with a new north-south route through the Site.

The design of the new Travel Center will work with the building&#;s integrated solar cell system on the vast roof surface to harvest the sun&#;s energy, with the capability of covering nearly % of the project’s energy demand. The indoor climate will be managed through natural ventilation, and heating through underfloor heating, and the potential use of floor cooling and rainwater recycling. Conditions will be improved for public transport in the city, providing a natural flow for bicycles and pedestrians, as well as passengers switching between modes of transport. These benefits along with charging stations and places for micro-mobility will reduce citizen’s reliance on cars.
