Mansion on Broadway

The venue’s own line is the useful one: it hosts a single event at a time, so the mansion is yours for the day. That is a first party claim and The Knot repeats it. The building went up in 1899, has been through what the venue describes as a multi million dollar renovation, and now runs to 13,000 square feet at 139 North Broadway in White Plains. Anyone can book it. There is no membership and no sponsorship. What there is not is a published price. No per person figure, no package rate and no menu prices appear anywhere on the venue’s own pages. The Knot and WeddingWire both list a reception starting at $10,750 plus an $850 ceremony fee, and both note that starting prices exclude service fees, taxes, gratuity and rental fees. The Knot also shows a $12,450 figure for what couples typically spend. That one is generated by the platform rather than charged by the venue, so we are not treating it as a price.

One event at a time is the claim the venue stakes, and a listing backs it

Exclusivity is the strongest thing this venue publishes about itself, and it publishes it in its own words: a single event at a time, so the mansion is yours. The Knot corroborates that the venue hosts one event at a time. For a building with a main ballroom and four further rooms, that is the difference between a wedding and a shift.

It also changes how you read the square footage. Thirteen thousand square feet across five rooms, a patio and a ceremony area is a lot of building for 200 people, which is roughly where both marketplace capacity figures land. Ask which rooms are included in your hire and which are staff or service space.

Exclusivity has a second effect worth pricing. A venue running one event a day can usually give you the building earlier, which matters if a florist needs three hours or a band needs to load in through the front door. Ask what time access starts, what time it ends, and whether either is negotiable or costs extra.

The tasting is included, and that tells you where the money goes

The venue cooks on the premises and includes a custom designed menu with a tasting for the couple. In house catering with an included tasting usually signals a business built around food cost rather than room hire, which is consistent with a starting price that covers a reception rather than a bare room.

That is the frame for every question about the quote. Ask how many people may attend the tasting, when it happens relative to the deposit, and whether the menu you taste is the menu you are quoted. Ask what a per person upgrade looks like, since the venue publishes no menu prices at all.

1899, a renovation, and 13,000 square feet the venue never breaks into rooms

The venue dates the building to 1899 and describes a restored antique mansion, remodelled for modern events after a multi million dollar renovation. No architect and no original owner are published, so the history stops at the date.

The spaces are described the same way: one main ballroom with access to four additional appointed rooms, plus an outdoor patio, a ceremony area and a private bridal suite. No individual room capacities are published by the venue. WeddingWire is the only source that sizes the ballroom, at up to 215. If you are choosing between a ceremony indoors and one on the patio, you will have to get the room dimensions on the tour, because nobody has printed them.

The $10,750 is a starting point, and the exclusions are printed beside it

The Knot and WeddingWire agree on the headline: a reception starting at $10,750, with an $850 ceremony fee on top. Both platforms note that starting prices exclude service fees, taxes, gratuity and rental fees, and that season and guest count move the number. The venue itself publishes nothing, so those two listings are all there is.

The Knot also publishes $12,450 as a typical spend. That is a platform estimate built from its own data, not a rate the mansion charges, so it should not be used as a budget line. The gap between a starting price and an estimated spend is exactly the gap you should be asking the venue to close in writing, with the service charge and the tax treatment named.

The two platforms disagree about how many people fit

The Knot lists the venue at 151 to 200 guests. WeddingWire lists 100 to 200, with the ballroom at up to 215. The venue publishes 13,000 square feet and no guest capacity at all. Both marketplace figures are recorded here and neither is reconciled, because averaging them would invent a number that no source stands behind.

If your guest list is near 200, this matters more than it looks. Ask for the seated capacity with a dance floor, with a band rather than a DJ, and with a sweetheart table or a head table, because those three configurations rarely produce the same answer.

They also disagree about whether you can bring your own vendors

The Knot describes the venue as an in house caterer and says outside catering is not permitted. WeddingWire agrees that in house catering is required but states that outside vendors are permitted. The venue’s own site confirms in house catering and staffing and a complimentary tasting for the couple, and publishes no vendor policy at all.

So the catering answer is settled and the vendor answer is not. Before you sign a photographer, a band or a florist, get a written statement covering outside vendors, any fee attached to them, and the insurance the venue requires from them.

What is included, and what is still open

The inclusion list the venue publishes is broad for the price band. A private bridal suite. A custom designed menu with a tasting for the couple. The ballroom and the outdoor patio. Linens, tables, chairs, china, silverware and glassware. Portable bars with premier liquors. Coat check, private parking and valet, WiFi and event planning. Catering is entirely in house and made on the premises.

What is open: the food and beverage minimum, the service charge, the end time and the rain plan, none of which appear on the venue’s pages or on either listing. There is an outdoor patio and an outdoor ceremony space with no stated indoor fallback, which is a question for a July booking. One filing quirk to ignore: The Knot files the venue under North White Plains while the address is White Plains 10603. Same building.
