AEW Capital Management and Seyfarth Shaw LLP have renewed their leases, totaling 150,000 square feet through 2020 and 2021, respectively, at World Trade Center East in Boston’s Seaport District.

Jones Lang LaSalle Managing Directors William Barrack and Bill Collins represented Pembroke Real Estate, the real estate investment and development advisor for Fidelity Investments and developer of the Seaport World Trade Center Complex, in the negotiations.

AEW, an international real estate investment advisory firm, and Seyfarth Shaw, a major national law firm, have been tenants in the 16-story building since its opening. World Trade Center East is currently 100 percent leased.

“The decision for AEW and Seyfarth to renew at World Trade Center East is a reflection of the development, as well as the success of the expanding neighborhood,” said Edward C. Johnson IV, senior vice president, North America for Pembroke Real Estate.

World Trade Center East is a 504,000 square foot mid-rise, Class A office tower and the first office building in Boston’s Seaport District. The building is part of the Seaport World Trade Center Complex, a 2.26 million-square-foot mixed-use development that also includes World Trade Center West, the World Trade Center Boston and Seaport Hotel.

Jones Lang LaSalle represents Pembroke Real Estate in all leasing activities at World Trade Center East and West.
