Keystone Building

The Keystone Building provides office and support space for four state agencies: the Department of Transportation, the Public Utilities Commission, the Department of Community and Economic Development, and the Pennsylvania Historical and Museum Commission. Located in the monumental Capitol Complex in Harrisburg, the 940,000 gross square foot building's massing, proportions, materials and character thoroughly integrate it into the historic complex. On each fa·ade the granite base, limestone walls and glazing are varied in response to the differing site conditions.

Organized as a "U" shaped plan around an enclosed interior atrium, the ten-story building provides office space for 3,700 people. Special facilities include hearing rooms for the Public Utilities Commission, a helipad, a 200-car underground parking garage, a food-service facility, and a daycare center.

Regard for long-term flexibility, energy use, and sustainabilty played an important role in the design of the building. Large floor plates, averaging about 80,000 gsf, are designed to provide the flexibility to adjust to new and changing workgroup concepts while assuring orientation and wayfinding for users and visitors. Extensive yet controlled, daylighting features improve the building environment and reduce energy consumption. Raised access flooring is used in all areas of the building to achieve a very high degree of personal control of individual work environments and improved indoor air quality while overall consumption of energy is reduced. The raised floor system also allows for complete flexibility in current and future electrical and telecommunications/data wiring.

The $123 million building was completed on budget in late 2000. It was designed by Bohlin Cywinski Jackson in a joint venture with Hayes Large Architects.
