CLIENT: PENNSYLVANIA REAL ESTATE INVESTMENT TRUST (PREIT)

Renovation of the historic Strawbridge’s Building encompassed six floors and sub-basement levels while the remainder of the building remained fully occupied. It included 225,000 square feet of new office space on floors 4-6; 315,000 square feet of mixed retail on floors 1-3 and the mall concourse; upgrades to 100,000 square feet of common areas such as lobbies, mechanical rooms, a pedestrian bridge, and repairs to the façade.

The project involved demolition and reconstruction of interior spaces, replacement of HVAC and plumbing systems, and renovation of electrical and fire protection distribution systems. Demolition crews used care to save ornate plaster beams between columns as well as numerous rosettes and column moldings. The Corinthian Dining Room’s historic wood paneling, crown molding, and French doors were restored, and the chandeliers and lead glass windows were preserved. Original elevator doors were re-installed. An existing grand staircase was disassembled and stored for future use.
Interior fit-out included 225,000 square feet of offices for the Pennsylvania Department of General Services. This work involved extending the base building HVAC, plumbing, and electrical distribution systems into the space. Our team successfully coordinated the work of multiple tenant vendors—including security, tele/data, demountable partitions, systems furniture, conference and storage furniture—to allow for a seamless transition to occupancy 3 months ahead of schedule.

The Core and Shell phase achieved LEED GOLD certification from the U.S. Green Building Council.
