Project Specs

Location: Washington, DC
Architectural Partners: Roger Stirk Harbour + Partners
General Contractor: Clark Construction
Completed in: 2010

Scope of Work

Over 6,000 meters of steel guardrail including 6mm stainless-steel cable


Two office buildings – one preexisting and one new – connected by a glass atrium make up America’s Square – a 461,484 SF LEED Gold certified law office property in downtown DC. Constructed in 1935, the law firm building at 51 Louisiana Ave NW was designed by the internationally acclaimed architect Lord Richard Rogers. The monumental stair sits in the atrium of America’s Square, connecting the historic 51 Louisiana Ave NW building with the new building at 300 New Jersey Ave. Several elevated platforms and walkways cross the atrium at different heights, linking the two adjacent buildings and interior workspaces. Over 6,000 meters of steel guardrail including 6mm stainless-steel cable attached to structural steel C-channel stairs and glass plank bridges, connect to the bright yellow “tree” structure, housing the atrium’s mechanical systems and glass observation elevator.
