Le Chateau

Le Chateau is a 1907 Tudor mansion on 25 acres at 1410 Old Post Road in South Salem, commissioned by J.P. Morgan as a gift for the Reverend William S. Rainsford and designed by Atterbury & Atterbury. Fairfield Catering Group bought it in the fall of 2016, spent a stated $10 million on renovation and expansion with KG+D Architects, and reopened it in 2017 for private events only. The venue hosts one event at a time and says so in writing. Capacity is up to 250 on the venue’s own home page, though Eventective and The Knot both list the ballroom at 265. The package is unusually specific for Westchester. Five hours: a one hour cocktail reception and a four hour seated dinner. Six butler passed hors d’oeuvres and three cocktail stations. A three course plated dinner, a five hour premium open bar, a cake from DiMare Pastry Shop, a champagne toast and table side wine service. What the package does not carry is a price. The venue’s own pricing page publishes none, and says only that pricing varies by season, day, time of day and guest count.

One event at a time, in the venue’s own words

The venue states on its own site that it hosts just a single event at a time and that the 25 acre estate is yours for the day. That is a first party statement, which puts it in a different class from the marketplace guesswork that fills most of this file.

It is also the single most expensive thing a venue can promise, because it means the property sells one Saturday rather than two. Expect that to be reflected in whatever number they give you on a tour.

The package is fully specified and completely unpriced

Almost nothing is left vague. Five hours of event time split one hour cocktails and four hours dinner. Six butler passed hors d’oeuvres. Three cocktail stations. A three course plated dinner. A five hour open bar with premium liquor, beer and house wines. Wedding cake with coffee and tea. A champagne toast and table side wine service.

Staffing is named too: a dedicated event coordinator, a maitre d’ and a personal attendant, plus private suites with refreshments and floor length ivory linens and napkins. Everything is listed except what it costs.

The pricing page carries one sentence of substance, which is that package pricing varies by time of year, day of the week, time of day and number of guests. You are directed to schedule a tour. That is a common structure at this end of the market, and it means you cannot compare Le Chateau to anything else until you have sat down with them.

Two hundred and fifty, or 265, depending who you ask

The venue’s home page says it accommodates gatherings up to 250 guests. Eventective and The Knot both put the ballroom at up to 265. We print both and do not reconcile them. Nobody publishes a separate ceremony or cocktail capacity, and no per room figures exist at all.

For a guest list in the 240 to 265 range, that 15 seat gap is the difference between a tour and a wasted afternoon. Ask what the Rainsford Ballroom seats with a dance floor and a band in place.

The marketplace estimates are not the venue’s prices

Eventective shows $20,000 to $50,000 per event for 100 to 268 attendees and derives a figure of roughly $75 to $500 per person from it. The Knot shows a $26,417 average price and labels it as a Knot Estimate. The Knot also publishes a ceremony starting at $500, with reception, bar and catering all listed as contact for price.

Only the $500 ceremony figure is a marketplace listing of a venue rate rather than a platform calculation, and even that is unconfirmed by the venue. The rest are estimates generated by the platforms. Do not carry any of them into a spreadsheet as though the venue had quoted them.

J.P. Morgan commissioned it, and the rooms still show it

The estate was originally named Savin Rock. The mansion is Tudor style in brick and stone, with American chestnut, cherry and oak paneling inside. The Knot’s listing independently cites the 1907 Morgan commission and the 2016 restoration, so the history is corroborated from two directions.

The named spaces are the walled garden ceremony area with arbors, the Pierpont Room for cocktail hour, the West Garden for photographs and a first look, and the Rainsford Ballroom for the reception, with terraced patios and grounds around them.

The garden ceremony has no published rain plan

The outdoor ceremony space is a private walled garden with arbors, described as seasonally landscaped. No wet weather alternative, no decision deadline and no move fee is published anywhere. With a mansion of this size the indoor fallback is presumably obvious, but presumption is not a contract.

Ask what happens at 9 a.m. on a rainy Saturday. Ask who makes the call and how late it can be made. Ask where the ceremony moves to and whether the change is charged for.

Two phone numbers, one of them in Connecticut

The site lists (203) 775-4517 and (914) 763-1410. The first is the Fairfield Catering Group office line in Connecticut; the second is the local Westchester number. The venue itself is firmly in Westchester County, in the Town of Lewisboro.

The operator is worth a line of its own. Fairfield Catering Group says on the site that it has run event venues since 1986, and it is the same company doing your catering, your bar and your coordination. There is no separate caterer to play off against the venue, which simplifies the planning and removes a lever from the negotiation.

On timing, the venue publishes no closed season. The Knot notes a peak season of June to July and September to October, which is a marketplace observation rather than a venue policy. If you are flexible, ask whether a January Saturday is priced differently from a September one.

One address note as well. The dataset behind this listing writes the address as 1410 NY-35. The venue writes it as 1410 Old Post Road, Route 35. They are the same road.
