A Private Pricing Opinion — what your apartment at The Royal Summit would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
310 West 86th Street is the western half of The Royal Summit — the celebrated pair of 1915 prewar buildings, designed by Mulliken & Moeller, that stand shoulder to shoulder on West 86th Street just off Riverside Park. The two buildings share a name, an architect, and one of the most admired entrances on the Upper West Side: a richly modeled terra-cotta lobby finished in deep brown glaze that consistently ranks among the most beautiful in the city. Stepping in from the street feels like arriving somewhere, not just entering an apartment building.
The location is the other half of the case. The Royal Summit sits roughly half a block from Riverside Park, with the park's tennis courts, the 79th Street Boat Basin, riverside dining, and the Hudson greenway all a short walk away, on one of the quietest and greenest blocks on the West Side. At twelve stories and 34 residences, 310 is an intimate, full-service co-op of large prewar apartments — the kind of building where the staff know every owner.
For buyers, it offers a rare mix: a small, exquisitely detailed prewar co-op, fully staffed, steps from the park, with owner-friendly terms — a cooperative since its 1981 conversion and carefully run throughout.
Architecture and unit composition
Mulliken & Moeller gave The Royal Summit a dignified prewar massing, but the lasting impression is the ornament — the lavish terra-cotta of the entrance and lobby, its dark-brown glaze catching the light in a way that flat modern materials never do. It is craftsmanship that simply isn't built anymore, and it sets 310 apart even among its prewar neighbors.
With 34 apartments across twelve floors, the homes are large, ranging roughly from one to four bedrooms, and carry the ceiling heights, deep windows, and generous proportions of 1915 construction. The relatively low unit count means strong light, good exposures, and a real sense of privacy; many residences have been carefully updated over the building's co-op decades while keeping their prewar character intact.
Building operations
310 West 86th Street is run as a full-service cooperative. A 24-hour doorman, porters, and a live-in resident manager handle the building, and amenities include a central laundry, a bike room, and private basement storage. Washer/dryers are permitted within apartments.
On policy, the co-op is comparatively flexible for a prewar building: financing is permitted up to 75 percent of the purchase price, the building is pet-friendly, pied-à-terre purchases are considered case by case, and subletting is allowed with board approval. Combined with the building's small size and full staffing, those terms make it an unusually comfortable prewar address to own.
Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01247-0040) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.
What to know if you’re buying
This is a prewar cooperative, so plan for a board package and interview — but the terms are friendly: 75 percent financing, pet-friendly, and pied-à-terres considered case by case. Maintenance funds the 24-hour staff and the upkeep of a finely detailed 1915 building, and is money well spent on a building of this character.
What you are buying is a large prewar apartment in a small, beautiful, fully staffed co-op half a block from Riverside Park — a combination that rarely reaches the market. We help buyers read the financials, understand the board, and target the homes and exposures that make the most of the building's light and its park-adjacent setting.
What to know if you’re selling
The selling story is the building's distinction: the famed terra-cotta lobby, the Mulliken & Moeller pedigree, the half-block walk to Riverside Park, and the flexibility of 75 percent financing in a small, full-service co-op. That combination reaches a deep and discerning audience.
Price against the Riverside / West End prewar cohort, adjusting for floor, exposure, and condition. A renovated, light-filled apartment will lead the market; a dated one leaves value that pre-sale preparation can recover. We position each listing to the right comparable set, showcase the building's character, and manage the board process to a clean close.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
