The Alyx at EchelonSeaport is a defining contemporary landmark designed by internationally lauded Kohn Pedersen Fox architects of New York. The impressive stepped tower design takes inspiration from Boston's Victorian neighborhoods full of brick and brownstone row houses, and puts a modern spin on it, showcasing oversized windows with city, courtyard, and water views. On the interior, the design team at world-renown Jeffrey Beers International, crafted the lobby and amenity spaces to feel like an extension of one's own living room; warm, inviting, and comfortable. Designed with a sense of community, the amenity experiences encourage residents to gather and socialize.
