About 121 Seaport

121 Seaport Boulevard, Seaport District, Boston, MA

The property features a 17-story, 450,000-square-foot tower located in the heart of Boston's Seaport District. 121 Seaport features 400,000 square feet of Class A office space above a two-story, 50,000-square-foot retail podium. 121 Seaport is 100%-leased, with tenants including Internet of Things (IoT) technology provider PTC, who occupy 250,000 square feet, and Alexion Pharmaceuticals, who lease 150,000 square feet.

121 Seaport tenant amenities include a private fitness center and a rooftop terrace with sweeping skyline and harbor views. 121 Seaport has seven high-speed elevators plus one service elevator; elevators will feature Destination Dispatch technology for reduced travel times. 121 Seaport has received LEED Platinum efficiency certification; the building's elliptical design will result in 15 percent energy savings due to less direct solar exposure.

Harbor Way, a 70-foot wide pedestrian retail promenade with 20,000 square feet of tree-lined open space, is located at 121 Seaport's base. The promenade features an interactive pedestrian museum honoring the history of the Seaport District's development. Underneath 121 Seaport is a parking garage with space for approximately 270 vehicles and 270 bicycles.
