Abigail Kirsch at Tappan Hill Mansion

Tappan Hill Mansion stands at 81 Highland Avenue in Tarrytown, on ground its own property page calls the former Mark Twain estate. Abigail Kirsch runs it as one of the catering company’s Signature Properties, so the building and the kitchen arrive as a single contract. Two reception rooms carry the only firm numbers a couple is given up front. The Pavilion Room takes 150 to 250 guests. The Hudson Room takes 75 to 150. After that the published record runs dry. We read the property page, the Signature Properties index and the marketplace listings, and found no per person rate, no site fee, no food and beverage minimum and no service charge. The Knot shows an estimated average total of $26,417 here, which is a marketplace estimate rather than a figure the venue has ever published. What is genuinely simple is access. Anyone can inquire. There is no membership, no sponsor and no gate, only a contact form and the number (914) 631-3030.

Two rooms, and the smaller one still starts at 75 guests

The Pavilion Room is the big one, published at 150 to 250 guests. The Hudson Room is the mid size option, published at 75 to 150. Both figures come from the venue’s own property page, and The Knot’s listing repeats them. That pair of ranges tells you something useful about who this property is for. A 40 guest wedding has nowhere obvious to sit.

The site also references garden terraces and further rooms inside the mansion without attaching a capacity to any of them. So if you are picturing a ceremony on the lawn and cocktails on a terrace, you are working from photographs rather than from published numbers. Ask for the terrace capacities in writing, and ask whether a terrace ceremony changes the room you get for dinner.

The kitchen and the building come from the same company

Abigail Kirsch is the operator here, not a preferred caterer you choose from a list. Food, beverage and planning are supplied by the company that holds the property. There is no outside caterer option published, and nothing on the site suggests one exists.

That has a practical effect on how you negotiate. With a rental venue you can move money between the room and the food. Here the room and the food are one line item, controlled by one party. No approved vendor list is published for florists, bands or photographers either, so the rules for everyone else on your team are still an open question.

The only number in public is The Knot’s, and it is a total

The Knot publishes an estimated average total of $26,417 for this venue. That is a marketplace figure. Abigail Kirsch has not published it, has not confirmed it, and publishes nothing to compare it against.

The Knot describes its estimate as covering site fees, catering, bar service, food, cakes and desserts, planning, service staff and shuttle. It does not break any of that out, and it gives no guest count to attach the total to. We will not divide it by a guest number to produce a per person rate, because that would invent a figure nobody published. Treat $26,417 as a rough order of magnitude and nothing more.

Nothing is published about end time, exclusivity or rain

There is no stated event end time or curfew. There is no statement that the mansion hosts one wedding at a time. The property has two separately named reception rooms, which means nothing published rules out a second event running down the hall from yours on the same evening.

The garden terraces are referenced with no wet weather policy attached. All three of these gaps matter on a Saturday in June. Put them in your first email: how late can the band play, is the building ours alone, and who calls the rain move, and when.

The Mark Twain connection is the venue’s phrase, and that is all we can confirm

The property page says the mansion sits on the former Mark Twain estate. We could not find a build year, an architect or a date the estate changed hands anywhere on the site. So the history you will read in a brochure is currently one sentence deep, and this page will not extend it with material the venue has never published.

One broken link to know about before you start emailing

The address carried in the scraped dataset, with a /catering-events/ segment in the path, is no longer the canonical page. The live page is at abigailkirsch.com/signature-properties/tappan-hill-mansion/. If an older listing sends you somewhere odd, that is why.

The WeddingWire listing for the property returned a server error when we tried it on 11 September 2026, so we could not read it. If you find pricing there later, remember which column it belongs in. It is marketplace, rather than the venue’s own rate card.

Two rooms and no rate card means the first email does the work

Because the published record is thin, the first email does most of the work. Ask for the per person rate in the Pavilion Room and the Hudson Room separately, by season and by day of week, since a 250 guest room quoted at a 160 guest wedding often carries a different floor.

Ask for the service charge and any administrative fee as percentages, and ask whether sales tax applies to the service charge. Ask whether the mansion hosts one wedding at a time, and what sole use costs if it does not. Ask what time music has to stop and what time you have to be out of the building.

Finally, ask about the terraces. Are they included, do they carry a separate fee, how many people fit on them, and what happens to a terrace ceremony in rain. None of those five has a published answer, which means all five are negotiable and all five belong in writing before a deposit moves.
