Renovating the Pentagon

Pentagon Wedge One and Wedge Two Renovations
Arlington, Virginia, USA

This project updated the 50-year-old building to meet new aesthetic and functional needs while dramatically improving its technological capabilities.

HOK provided extensive design services for the Pentagon’s Wedge One renovation. This included the complete renovation of each of Wedge One’s five floors. The improvements were so extensive that the building interior was demolished down to its concrete shell and completely re-configured.

After the Sept. 11 attacks, HOK participated in the reconstruction effort as architects for the exterior and tenant fit-out portions of the Wedge Two project. The design and construction schedule for this 400,000-sq.-ft. project, which could have required three years with a typical schedule, was compressed to just 10 months.
