This 1968 structure was expanded vertically by two additional floors. The addition of 45,000 SF facilitated a redevelopment strategy that transformed the building into a new and vibrant workplace. The program included new facades, public spaces, core, building systems and semi-public amenity areas. The primary design challenge was to weave new architecture through an existing structure and core footprint. Another principal challenge involved creating two viable floors in only 20 feet of additional height.
The design solution creates an “honest,” modern architecture that is both confident in, and respectful of, its urban context. This is reinforced at both the scale of the city and within the building’s detailing. A transparent curtain wall system, absent any opaque spandrels, reveals the concrete structure within. A central reveal in the building’s curtainwall provides a break to the overall façade system and aligns with the building’s internal core and central lobby. The building “opens” here to permit a more direct visual and physical connection to the street. Glass within the central reveal is clearer. The intention is to create movement in the façade, revealing the functions behind. Slab extensions allow the new façade to engage the street wall. New mechanical and plumbing systems are surgically woven through structural beams to achieve viable ceiling heights, while maintaining 75% of the original structural frame. Green roofs, energy efficient systems, daylighting strategies and sustainable technologies support state-of-the-art workplaces.
Our team increased the building by two floors and filled in open courts of the existing floor plate to add more than 45,000 gross square feet. The new design provides a state-of-the-art work environment that is now competitive within the Washington Class A market. The successful outcome of this project exhibits and supports the ability to both foster economic development and practice sustainable design.
