Sands Point Preserve

The old Guggenheim castles on the Sound, booked park-style with approved caterers.

EstateParkWaterfront

You are booking a Gilded Age estate that Nassau County owns, on 216 acres above the Sound, with a 50,000-square-foot mansion in the middle of it. Hunt & Hunt drew Hempstead House in 1912. The entry foyer is sixty feet tall. There is a 150-guest minimum before the conversation starts, and that number alone decides whether this page is for you.

The numbers, labeled

Per person
Not published. CulinArt is the exclusive caterer and publishes no per head on the Sands Point pages we read, the Conservancy's own site refused our request, and WeddingWire shows no per person figure either.
not published
Site or rental fee
Nothing first party. WeddingWire lists a reception site fee starting at $60,000 in both peak and off peak with no ceremony fee, and does not say whether that covers the rental alone or a package with CulinArt's food inside it. That is the largest and least explained starting figure on this site.
marketplace
Food and beverage minimum
A 150 guest minimum, from CulinArt's own Sands Point pages. That single number decides whether this venue is available to you at all. No dollar minimum is published anywhere we read.
first party
Service charge and gratuity
Not published. No percentage, no tax handling and no deposit figure on any source we reached.
not published
Outside vendors
CulinArt Group, which also trades here as Philip Stone Caterers, is the exclusive caterer and runs the venue's own event site. There is no outside caterer option. No rules or fees are published for outside vendors in any other category.
first party
Capacity
From CulinArt's own Sands Point pages: Hempstead House holds up to 300 seated and 350 for cocktails. The Great Hall at Castle Gould takes 100 for dinner and 150 for cocktails. The Black Box, a 7,000 square foot New York State certified sound stage, takes 400 seated or 500 for a party. The Great Lawn is described as tentable with no number attached. Marketplace figures run lower and disagree: WeddingWire says up to 320 across spaces, its Long Island mansion directory page says 250, and Eventective gives the Black Box 500 and the Great Hall 150.
first party
One wedding at a time
Not published. No exclusivity statement on any source we reached, which is worth pressing on given that Hempstead House and Castle Gould are separate buildings on the same 216 acres.
not published
End time
Not published. This is a Nassau County park, so the park's closing hour and its noise rule are separate constraints from the catering contract. Ask for both in writing.
not published
Rain plan
Not published. WeddingWire lists indoor, covered outdoor and uncovered outdoor settings and states no contingency. The Great Lawn is described as tentable, which is a rain plan you pay for rather than one you are given.

The gate here is the 150 guest minimum on CulinArt's own pages, and it settles the question before price does. What follows is a Gilded Age estate Nassau County owns on 216 acres above the Sound. Hunt and Hunt's 1912 Hempstead House sits in the middle of it at 50,000 square feet, and the four event rooms have very little in common. The catering answer is clean: CulinArt is the caterer, not a name on a preferred list, and it runs the venue's own event site with the capacities on it. The pricing answer is not clean at all. WeddingWire's $60,000 reception start is the biggest number on this site and the listing never says whether food is inside it, so make CulinArt give you the rental line and the food line as two separate figures.

Capacities and the 150 guest minimum come from CulinArt's own Sands Point Preserve pages as read in our earlier pass. We also reached the WeddingWire storefront, the Eventective page, a WeddingWire Long Island mansion directory page and two Zola searches. The Conservancy's own site and a fresh fetch of CulinArt's Sands Point page both refused our request on 10 September 2026, and no The Knot or Wedding Spot listing was located. Checked September 2026. First party means the venue’s own site or rate card; marketplace means The Knot, WeddingWire, Zola, Wedding Spot or similar. Nothing here is averaged or estimated.

INCOMPLETE on price: first party capacities and the guest minimum are in hand, but no first party rate or dollar minimum was obtainable. The $60,000 WeddingWire figure's scope is unexplained, and marketplace capacities run 250 to 350 against the caterer's own higher room by room numbers.

Two mansions, four rooms, four very different nights

Hempstead House is the one people picture: 50,000 square feet over three floors, 225 feet long and 135 feet wide, 40 rooms, per the Conservancy’s own page on the house. Inside are the winter and summer living rooms, a library, the dining room, the billiards room and a sunken palm court with a cherub fountain. Bridal and groom suites are on the second floor. The Rose Garden and the terrace face the Long Island Sound.

Castle Gould is the other building, and its two event spaces have nothing in common. The Great Hall seats 100 for dinner and holds 150 for cocktails. The Black Box is a 7,000-square-foot New York State-certified sound stage that takes 400 seated or 500 for a party. Hempstead House itself is listed at up to 300 seated and 350 for cocktails.

Those capacity figures come from CulinArt’s Sands Point pages, not from an aggregator. The Great Lawn is described as tentable for large receptions, with no number given.

The catering question, answered

CulinArt is the caterer. Not a preferred vendor on a list of six, the caterer, running its own Sands Point Preserve site with the spaces and capacities on it. That distinction is the whole budget. Gold Coast estates divide into houses with a working kitchen and a house caterer, and park-run sites where you assemble the kitchen, the rentals, the staff and the rain plan yourself.

This is emphatically the first kind. Any description of Sands Point that has you bringing your own caterer is describing a different venue.

The 150-guest floor, and the price nobody publishes

The Conservancy states a 150-person minimum for private events. Below that you can ask about the Great Hall or a weekday, but understand that you are asking for an exception rather than reading a menu.

There is no rental fee published. None, anywhere. The event inquiry form asks for your date, your guest count and your budget, and routes to a hospitality manager. For a property this size that is normal practice, and it is also exactly why the pricing page is worth reading before you dial. Walking in with a Nassau median in your head is the difference between a negotiation and a quote.

The organ, and the third house

In the 60-foot entry foyer there is a Wurlitzer Opus 445 theater organ, fully restored, which the Conservancy uses for concerts and lectures through the year. Whether it is playable on a Saturday night in September is a question for the hospitality manager, and it is a better one than most couples think to ask.

Falaise is the third mansion on the property, Harry Guggenheim’s, deeded to the county in 1971 as a museum site. Neither the Conservancy’s weddings page nor CulinArt’s space list includes it, so do not assume you can book it. Our record says two mansions; there are three buildings you will walk past.

The history is the amenity

Howard Gould, son of Jay Gould, built Castle Gould first and finished it in 1902. Daniel Guggenheim bought the estate in 1917. Harry Guggenheim took 90 acres in 1923 and built Falaise; when he died in 1971 that piece was deeded to Nassau County as a museum site, and the county acquired 127 acres the same year. The Friends group formed in 2003, took over management in 2008, and became the Sands Point Preserve Conservancy in 2016.

One more thing, and it tells you how the rooms read on camera without me describing photographs I have not seen. Hempstead House has stood in for period New York in Scent of a Woman, The Blacklist and The Gilded Age. Location scouts are ruthless about this sort of thing, and they keep coming back.

This is an unclaimed listing. If you run Sands Point Preserve, claim it free to add your photos, capacity, packages, and pricing.
