Capturing sweeping views of Boston’s premier Seaport neighborhood, downtown and Boston Harbor, EchelonSeaport is perfectly poised to redefine urban luxury living in one of the nation’s most historic, culturally rich cities.  Designed by internationally acclaimed architect Kohn Pedersen Fox with interiors by Jeffrey Beers International (of Four Seasons, Langham Hotels and Ritz-Carlton fame), EchelonSeaport’s 133 Seaport A Regent Collection luxury tower houses 255 condominiums, the crown jewel of which is Penthouse 1B, an incredible three-bedroom, two-and-a-half bath residence offered at $4.9 million and represented by Mauricio Umansky and Santiago Arana. 

Showcasing stunning, wraparound city and sunset views, Penthouse 1B’s soaring ceilings, jaw-dropping floor-to-ceiling walls of glass and white oak hardwood floors add to its modern, sophisticated feel. The open gourmet kitchen—bedecked with custom Italian cabinetry and a premier suite of chef-inspired Gaggenau appliances—is an entertainer’s dream. The magnificent, 469-square-foot private terrace offers unprecedented city views, which can also be enjoyed privately from the opulent master bath’s luxurious marble soaking tub and oversized spa shower. 

Impeccable, resort-style services and amenities abound for residents of EchelonSeaport—whose service standards are provided by Regent, a top luxury hotel brand. Set on 3.5 acres, the building’s two lower levels of retail and restaurants are paired with over 50,000 square feet of indoor and outdoor amenities—from one indoor and two outdoor pools to cutting-edge fitness facilities, which house an indoor basketball court, golf and sports simulator and yoga studio. Perfect for large get-togethers, EchelonSeaport’s Club Level features a fireplace lounge, private gathering and dining areas, a wine room and outdoor terraces with grill stations and fire pits. With social lounges, al fresco dining areas and poolside sun terraces with cabanas, EchelonSeaport was designed to accommodate the modern luxury lifestyle, with everything one needs to lead an active, wellness-centric, engaging and connected lifestyle all in one place. 

EchelonSeaport’s enviable location (a less than ten-minute drive from Logan International Airport) places it in the heart of one of Boston’s premier neighborhoods. With extraordinary connectivity on foot, by car, public transit or by water taxi, the cosmopolitan Seaport District is a culinary destination in its own right, with renowned restaurants from multiple James Beard award-winning chefs just moments from home. EchelonSeaport is not just another residential address: it is an unprecedented urban resort that represents a new chapter of innovation for one of the city’s most historic neighborhoods—with Penthouse 1B at its peak of sophistication.
