Anchoring a full city block in the heart of the Seaport, Echelon delivers a large-scale, amenity-driven approach to luxury living—where residential design meets a true lifestyle ecosystem. Comprising two interconnected towers, this development blends modern architecture with a highly activated, service-forward environment.

From the moment you enter, the tone is set. A double-height lobby designed by Jeffrey Beers features layered materials—stone, wood, and metal—creating a warm but elevated first impression. Residences continue that theme, with oversized window walls that bring in natural light and capture views of the city and Boston Harbor.

Layouts are open and efficient, designed for both everyday living and entertaining. Kitchens are sleek and modern, with imported cabinetry and a full suite of appliances from Thermador. Finishes are clean and contemporary throughout, giving each home a polished, move-in-ready feel.

Where Echelon truly separates itself is in its amenity offering. The building functions almost like a private club, with a comprehensive lineup that includes a full fitness center, indoor pool, basketball court, and dedicated yoga studio. The fifth-floor terrace serves as a centerpiece—featuring an outdoor pool, cabanas, and multiple lounge and dining areas designed for both relaxation and socializing.

Location is exactly where you want to be. Positioned directly on Seaport Boulevard, residents are steps from the neighborhood’s top restaurants, retail, and waterfront access points, with easy connectivity to downtown andLogan International Airport.

For buyers seeking a turnkey, amenity-rich lifestyle in one of Boston’s most active neighborhoods, Echelon offers scale, convenience, and a highly social living experience—all within the Seaport’s core.
