1100 First Street, NE

Washington, DC

This building redefines the expectations of the speculative office building. Designed as two distinct blocks on a 1.7-acre site, the forms of this glass-clad building emphasize the vertical and activate a dynamic courtyard at the center of the complex. This space brings natural light deep into the site and identifies the building’s main entry.

Glass, the building’s exterior material, is used in two different but related ways: cleanly detailed and folded at the courtyard in a manner that lightens the volume and clearly identifies the main façade, and more deferential and modular at the adjacent streets.

A high-performance façade, which uses glass in varying directions for careful infiltration and controlled reflection, provides for an open and light-filled building with daylight and views to over 75% of its occupied areas. Throughout the building, natural light penetrates deep into the plate from the floor to ceiling exterior glazing. All of the glazing units are insulated with a low-E coating, providing superior energy performance.

At the ground floor, the lobby opens up the building to the scale of the street. Detailed with care and sophistication, the lobby design draws upon the language of the exterior to create a distinctive identity.


LEED® Gold is achieved through site strategies, water savings, and energy efficiency.
