Sea Cliff Manor hosts corporate meetings, holiday parties, galas, social celebrations and weddings for up to 205 guests, in a ballroom of about 5,000 sq ft with a waterfront lawn and veranda. The estate, a former Gold Coast mansion, stands at 395 Prospect Avenue in Sea Cliff, on the North Shore of Long Island, about 28 miles from New York City.
Seminars and company events
The venue covers a wide range of business formats: off-site meetings, board and committee sessions, training days, sales kickoffs, award dinners, team-building days, client receptions, leadership retreats, fundraisers and galas. Holiday parties run from a relaxed after-work gathering to a black-tie dinner, and these dates fill several months ahead. Rooms and terraces are configured for each format, and the team suggests a room plan once it knows the headcount. Staff also handle the timing of speeches, toasts and award moments. On-site parking is available, and the team can help arrange car services or shuttles for guests coming from the city.
Weddings and receptions
Couples marry outdoors on the waterfront lawn, with views over the harbor, and hold the cocktail hour on the patio before moving into the ballroom. Private dressing suites are set aside for getting ready. The house also hosts bar and bat mitzvahs, sweet sixteens, anniversaries and milestone birthdays. Because the venue books only one event at a time, every package includes exclusive use of the entire estate.
Rooms and capacities
The Ballroom covers about 5,000 sq ft, takes daylight from several sides and holds up to 205 guests. The Outdoor Garden Veranda opens onto Long Island Sound and serves for receptions and cocktail hours. The Speakeasy Bar works as a smaller lounge for part of an evening, and the waterfront lawn hosts ceremonies. Dressing suites complete the layout for weddings and social events.
Catering
Catering is in-house, with seasonal menus from the executive chef and options for dietary needs and cultural traditions. Kosher-style menus are prepared in the house kitchen, while glatt kosher events use approved outside caterers. Bar packages are built to the event, and stations such as a whiskey and cigar bar, a craft beer bar or a martini bar can be added to a reception.
History and setting
The mansion was built around the turn of the twentieth century under the name Sans Souci. It later operated as Sans Souci of Sea Cliff, a French restaurant known locally for dinners, proms and family celebrations, before becoming Sea Cliff Manor. The setting is residential and close to the water, with Glen Cove, Roslyn and Oyster Bay nearby.
Getting there
Sea Cliff is in Nassau County and is easy to reach from the Long Island Expressway and the Northern State Parkway. The Long Island Rail Road serves the area, and the venue has its own parking.
