About Seaport Square Block L4

111 Harbor Way, Seaport DistrictBoston, MA

The project consists of a 17 story retail and office building to be constructed on a 1.63-acre parcel in Boston's Seaport Square.

The 525,000 square foot building will feature 81,000 square feet of retail space on the first two levels accompanied by 444,000 square feet of office space on the upper 15 levels.

WS Development has announced in the spring of 2018 that Amazon had signed to lease approximately 430,000 square feet of office space at a planned office building overlooking the Seaport District’s future Harbor Square public park. Approximately 2,000 Amazon employees would work at Amazon’s new space. Amazon’s lease would fill the planned building, located on Seaport Square Parcel L4 at the corner of Autumn Lane and East Service Road next to Skanska’s new 121 Seaport office tower, entirely.

Amazon will also be given an option to lease additional space at a planned building located across Harbor Square on Seaport Square Parcel L5, at the corner of Congress Street and Boston Wharf Road. The option would expire at the end of 2020 and require Amazon to employ at least 2,000 additional people in Massachusetts.

Construction Cost $435,000,000.00
Square Feet 525,000
