The US Citizenship and Immigration Services’ Philadelphia office will move from its Center City location at 16th and Callowhill to West Philly by the end of 2012.

The new office will be located in 2.0 University Place, a new University Place Associates LLC’s five-story building at 30 N. 41st St. where it will occupy the first three floors (53,000 of the 97,000 square-foot space). The 15-year, $26 million lease was negotiated by building leasing and the US General Services Administration reps. The building is currently under construction.

University Place Associates founder Tom Leonard told The Philadelphia Inquirer, “they looked at what was available in Center City, didn’t like it, and broadened their (search) to West Philadelphia.”

“This will be a much nicer facility,” he added.

Located at the foot of the University City Science Center, the building will feature an extensive green roof with a 20,000-sf rooftop park, high-efficiency HVAC systems, open floor plans with 90 percent natural daylight, ‘gray water’ recycling systems that utilize rainwater to operate restrooms, onsite bicycle racks, changing rooms, and car sharing facilities among other things.
