306 West 100th Street

The facade is the building's signature. A rusticated stone base sits above a brick basement, with Flemish-bond brickwork rising through the shaft, two-story Ionic pilasters, a carved door surround with a bracketed lintel, terra-cotta lintels accented with green glazed roundels, balconies and balconettes, and a deep copper cornice crowning the whole. It is a confident Beaux-Arts composition of 1910, and the historic-district designation means that character is protected — exterior alterations route through landmarks review.

Behind the limestone, the 32 residences carry the pre-war virtues that define the neighborhood: hardwood floors, defined rooms, generous closets, and the ceiling heights and light of pre-war construction, with the better light on the upper floors and the western exposures toward the park. The mix runs from one-bedroom homes to larger layouts, with renovation levels varying apartment to apartment.

306 West 100th Street operates as a self-service cooperative with a live-in superintendent, an elevator, and a marble lobby, supported by a central laundry room, a bicycle room, and private storage. It is not a doorman building — the structure that keeps maintenance efficient and makes the building's carrying costs sensible for a park-adjacent pre-war address.

On house rules, the building is pet-friendly, allowing both dogs and cats — a meaningful draw on a block where families and dog-owners gravitate toward Riverside Park. As at any cooperative, purchases require board approval and a full board package, and the board reviews financing and financials in line with a quality Upper West Side co-op; subletting is governed by the board rather than open to investors, keeping the building largely owner-occupied. A serious buyer's representative will confirm the building's current financing cap and sublet terms from the financials and house rules before an offer, and the historic-district status governs exterior work.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01888-0076) 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.

This is a board-approval cooperative, so plan for a full financial package and an interview. The value proposition is genuine Beaux-Arts pre-war character and a park-block address at a self-service co-op's efficient carrying cost — underwrite the maintenance and any assessment history against the 32-unit base, and read the financials for the building's reserve position and any capital plans, which weigh more in a smaller building.

The pet-friendly policy makes this a practical building for the dog-owning, park-oriented buyers the block attracts. For an owner-occupant who wants pre-war detail, a limestone facade, and Riverside Park at the end of the street without paying below-86th prices, the building's mix of character, location, and reasonable costs is the core of the case. The historic-district protection is itself a long-term asset, locking in the streetscape that draws buyers here.

Lead with the architecture and the block. A 1910 Beaux-Arts facade, a marble lobby, Riverside Park steps away, and protection within the Riverside–West End Historic District Extension II are precisely the qualities that distinguish a listing here from generic inventory, and they reward strong presentation.

Benchmark to renovated pre-war co-ops on the Riverside-and-West-End blocks at the north end of the neighborhood; a well-renovated, higher-floor home with good light should price toward the top of that set, while the building's relative value to the blocks below 86th is itself a selling point to value-minded pre-war buyers. Coming to market with current financials and the building's pet and sublet posture clearly stated removes friction. Because turnover is modest, a sharp listing can capture buyers who have been waiting for exactly this kind of character building on a Riverside block.
