Media group Thomson Reuters, headquartered at 3 Times Square, has signed an expansion lease with SJP Properties at Waterfront Corporate Center II, 121 River St., in Hoboken, N.J. The media giant has leased space at the corporate center since 2008.

With the new agreement, Thomson Reuters added 72,000 square feet for a total of 93,000 square feet, leasing the top three floors: the 10th, 11th and penthouse. WCC II is one of a three-building, mixed-use complex spanning 1.5 million square feet of class-A commercial space.

Thomson Reuters reportedly will be relocating 450 employees to the Hoboken office from New York City by the third quarter. A Thomson Reuters spokesman declined to comment on the lease.

“This expansion will provide a considerable boon to the local and state economies, with the New Jersey Economic Development Authority estimating a net benefit to the state of $123 million from this transaction,” Steven Pozycki, founder, chairman and CEO of SJP Properties, said in a statement.

Jeffrey Platte, a name partner at Platte, Klarsfeld, Levine & Lachtman in Manhattan, represented Thomson Reuters.

Martin Dowd, a partner at McCarter & English in Newark, represented SJP.

The overall asking rate for the waterfront building in Hudson County is $38-$39 per square foot, according to a Cushman & Wakefield’s first quarter report.

WCC I and WCC II are 100 percent leased. Currently under construction, WCC III is 40 percent preleased, including a lease with Pearson Education. Construction is expected to be complete in November. Ground level space will contain 25,000 square feet for retail use. There will also be a 200-car underground parking garage and on-site amenities include a state-of-the-art fitness center.

The Hudson Waterfront and Northern New Jersey are poised to see activity remaining brisk for the remainder of 2014, according to Cushman & Wakefield’s report. In January, Forbes Media signed a lease in Jersey City.

“The decision by Thomson Reuters to expand at Waterfront Corporate Center and relocate a large portion of its workforce to the complex can be attributed to Hoboken’s position as a premier transit hub that offers an unparalleled live-work-play environment,” said Pozycki.
