101 Dune Rd

Round Dune is a low-rise, oceanfront cooperative built in 1965 and composed of two stories with 76 residences lining Dune Road in the Water Mill/East Quogue area. Architecturally modest, the complex presents a straightforward beachside profile with multiple upper and lower units that emphasize outdoor access — many residences include private decks or balconies with panoramic bay and ocean views. Units are typically compact one-bedroom or studio plans; interiors commonly feature elements such as high and cathedral ceilings, exposed beams, eat-in kitchens or breakfast bars, granite or marble counters, wet bars, and first-floor primary layouts in select apartments. Shared facilities are oriented toward seasonal coastal living: an in-ground heated pool with sun decks, private ocean beach access with outdoor showers, landscaped common sitting areas, and laundry facilities. The property operates as a co-op with on-site maintenance, deck staff and 24-hour security; maintenance fees cover taxes, water and garbage and have been subject to periodic assessments. On-site parking and storage are available; pet policies and specific unit services follow co-op rules. Located steps from local dining like Dockers and positioned for dramatic sunsets, Round Dune caters to those seeking a managed, amenity-focused beach community rather than a high-rise urban experience.
