Seaport Condo Tower Tops Off

EchelonSeaport tower

Boston – Cottonwood Group joined Mayor Martin J. Walsh, John Moriarty & Associates (JMA), and elected officials recently to celebrate the topping off of 133 Seaport – A Regent Collection, the first condominium tower at EchelonSeaport, a 3.5-acre, 1.33 million sf mixed-use development on Seaport Boulevard.

 The highly anticipated project will deliver 447 luxury condominiums, 270 rental apartments, more than 60,000sf of indoor and outdoor private residential amenity space, 125,000sf of destination retail and dining, and a signature public courtyard to Boston’s most vibrant neighborhood. This construction will mark the completion of the steel structure for 133 Seaport – A Regent Collection, which is to be delivered in fall 2019.


The project was designed by a team of architects including Kohn Pedersen Fox (KPF), CBT, and Jeffrey Beers International. The property’s distinctive stepped-tower design, expansive terraces, and signature public courtyard not only reference the historic fabric of the city’s architecture but also encourage connectivity to the community through the creation of a public signature gathering space at the heart of Boston’s Seaport District.  


Amenities include two outdoor pools, an indoor pool, two sky lounges, an array of entertaining spaces, a fitness center and spa, a golf simulator, and even a half basketball court. Two levels of architecturally distinctive retail, to be owned and managed by WS Development, will blend eclecticism, superior quality, and a spectacular courtyard setting.

133 Seaport is the first condominium tower due to open at the end of 2019, with phased completion of the other two towers through 2020.
