Skanska Announces 121 Seaport Fully Leased as Alexion Pharmaceuticals Moves Headquarters to the Office Development

Press Releases

Firm’s Renowned Elliptical Tower Attracts Biopharmaceutical Leader that Develops Life-Transforming Therapies Skanska announced today that Alexion Pharmaceuticals, Inc. has signed a 150,000-square-foot lease for its state-of-the-art, elliptical office tower, 121 Seaport. Alexion will move its headquarters from New Haven, CT, to Boston.

Alexion, a global biopharmaceutical company focused on developing and delivering life-changing therapies for patients with rare diseases, will occupy a third of the building, from floors three through eight, starting in June 2018. Newmark Grubb Knight Frank represented Skanska as the developer and owner of the project, and Cushman & Wakefield represented Alexion.

Last week, PTC, a global technology provider of technology that transforms how companies design, manufacture, operate, and service the “things” in the Internet of Things (IoT), signed a lease for the upper floors of the building and will be moving in early 2019.

“121 Seaport now being 100 percent leased demonstrates the Seaport’s arrival as one of Boston’s most sought-after submarkets and business destinations,” said Charley Leatherbee, head of Skanska’s Commercial Development operations in Boston. “We delivered a building based on flexibility, innovation, sustainability and efficiency. We are honored that a pioneering company such as Alexion selected our building. Alexion and PTC are moving their respective industries forward in a building that pushes the boundaries of traditional design.”

Alexion will benefit from 121 Seaport’s unparalleled features including:
• virtually column-free floor plates that create flexible workspaces for customization;
• elevated 10-foot ceilings;
• panoramic waterfront views of the Boston Harbor and the city skyline;
• outdoor terraces;
• private, tenant-only fitness center;
• 24/7 hotel-style concierge;
• two floors of prime retail;
• direct access to neighboring parks, amenities and transportation.

121 Seaport is a 17-story, 400,000-square-foot, Class-A office building targeting LEED® Platinum certification, coming on line in the first quarter of 2018. The office tower sits in the heart of Boston’s booming Seaport District, across from District Hall and Seaport Square Green, on Boston’s most sustainable block, which is also home to Skanska’s 101 Seaport and Watermark Seaport developments. Designed by CBT, the building’s distinctive design will enhance the area’s architectural landscape, maximize the skyline visible from Seaport Square Green, and reduce solar heat gain when completed.

121 Seaport’s three-story lobby faces Boston Harbor and opens onto Harbor Way, a future expansive 70-foot-wide pedestrian retail promenade located between 101 and 121 Seaport with 20,000-square-feet of open space and an interactive walking museum that will commemorate Skanska’s #SeaportShipwreck discovery.

The transit-oriented building is adjacent to the MBTA’s Silver Line, and walking distance from South Station. It offers indoor bicycle parking spaces, underground parking spaces, and is a block away from I-93 and I-90 access ramps. The neighborhood has blossomed with retail and wellness options just steps away, including SoulCycle, Starbucks, By Chloe, CVS, Blue Hills Bank, Shake Shack, the ICA, Yo! Sushi, Equinox, Gather, and Ocean Prime, offering employees the prime atmosphere for work and play.

Since launching its commercial development business in the U.S. in 2009, Skanska has invested nearly half a billion dollars to self-finance smart, sustainable developments in Boston. The company has two additional developments in the Seaport: 101 Seaport, the North American headquarters for PwC; and Watermark Seaport, a 300,000-square-foot, LEED Gold residential building with ground-floor retail, which is more than 95 percent leased. Skanska also developed 150 Second Street, a lab and office building in Cambridge, MA, and is currently developing The Harlo, a luxury residential tower at 1350 Boylston Street in the Fenway, where both Tatte Bakery & Café and Oath Craft Pizza will be opening this fall.

Skanska has built and restored New England’s landmarks for more than 70 years, from Gillette Stadium and the Novartis Institute for Biomedical Research, to the Longfellow Bridge. Skanska continues to leverage its local knowledge and global expertise to shape the region's institutional, commercial, healthcare and life science facilities, as well as to enhance or expand essential transportation and energy infrastructure.
