Tysons Tower is a 19-story office tower on podium consisting of three above grade levels with combined parking/office/retail and four below-grade parking levels. Below grade GSF is 650,500, above grade GSF is 600,000, for a total GSF of 1,250,000. The base of the structure, to the Plaza Level, is clad largely with rubble stone from Finger Lake, New York and Indiana Limestone. Guests and tenants of the building are greeted by a cable wall that extends from the street level through the Plaza Level, including stainless portals with canopies providing access to the lobby space. The tower is clad with unitized curtain wall with custom extrusions designed specifically for this project. The Plaza and street levels include extensive landscape and hardscape over the structured parking, which extends below the existing roadway, bordering the southern property line. Over 125,000 cubic feet of structural insulation is required to make the grade transitions between the garage structure and street level, largely because of the utilities that run above the parking structure and yet below the road.
