The largest privately-owned repositioning project in the nation's capital is complete following a 5 ½-year design and construction process. After winning a three-month design competition, SmithGroup worked carefully with Ownership and an extensive consulting team to prepare Constitution Center as a 21st-century workplace that is highly secure, very sustainable, and a landmark headquarters for prospective tenants. The anticipated 5,000 future employees will enjoy wide-open, daylit spaces made flexible by a strong planning strategy and the use of chilled beams for the HVAC system. A one-acre garden courtyard acts as a welcome amenity, both by access and visual interest, while also working as a green roof above basement garage space for 1,500 vehicles.
