The Residences at Atlantis Marina is a low-rise, waterfront condominium community completed in 2008 and sited directly on Winthrop’s marina and Boston Harbor. The single-story building cluster and several penthouse-level layouts create a small, intimate complex of about 44 units with a mix of one- and two-bedroom residences plus corner penthouse configurations. Architecturally the development emphasizes broad windows and private balconies to maximize water and skyline views; building finishes include elevator access, heated underground garage parking with deeded spaces, and a concierge presence. Interiors typically feature open-concept plans with high ceilings, hardwood or exotic wood floors, upgraded kitchens with stone counters and stainless-steel appliances, in-unit laundry, and generous closet systems. Some units incorporate custom millwork, wet bars, private saunas, and panoramic covered decks. Shared amenities are focused on waterfront living and daily convenience: a fitness room, on-site concierge, direct marina access with assigned boat slips (leased separately), decorative landscaping, and controlled-entry building services. Exterior elements include multiple types of private outdoor space — balconies, covered patios and composite decking — as well as views across the marina toward the Boston skyline. Operationally the community supports two covered parking spaces per typical unit, sprinkler systems, broadband and cable hookups, and routine building services. Pet policies are permissive. The location places residents five miles from downtown Boston with nearby ferry and transit options, supporting a coastal, commuter-friendly lifestyle centered on boating, sunset views, and easy access to city amenities.
