329 West 108th Street

The Cloisters is, in effect, two 1890s mansions living a second life as a single apartment building. The combination produced a double-wide footprint and a stock of homes that retain mansion-era detail — oversized bay windows, leaded and stained glass, mosaic tilework, and exposed wooden beams — woven through layouts that were adapted from townhouse rooms rather than laid out on a developer's standard floor plate. That history makes the apartments idiosyncratic in the best sense: no two lines are quite alike, and the period character is original rather than reproduced.

With twenty-four homes across six floors, the building runs to gracious pre-war proportions on a low-rise, double-wide frame. The bay windows pull light into the principal rooms, and the apartments reward buyers who value architectural texture over the uniformity of newer construction. The roof deck — a genuine amenity in a six-story building — adds open-air space and long views over the surrounding low-rise blocks toward the river.

The Cloisters runs as the intimate house it is. The building offers a roof deck, a central laundry, bicycle and common storage, elevator service, and part-time doorman coverage, with a superintendent overseeing the property. The building is pet-friendly, a meaningful draw on this family-oriented stretch of the West Side. There is no pool or large gym — the model is a small, owner-occupied co-op that spends on service, the roof deck, and the structure rather than a deep amenity program. Common charges support staff, the systems of an early-20th-century masonry building, and the reserve, so compare actual maintenance, debt and assessments with corridor peers before judging costs.

Market read. $/sf is measured on the latest sales with reliable square footage (2023): a median $1,059/sf (recorded) across 1 sale. The building has traded as recently as 2025. Median listing discount 2.8% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01893-0006). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. 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.

The Cloisters is a traditional cooperative, so purchases clear a board package and interview. The building is pet-friendly, pied-à-terre ownership is permitted, and subletting is permitted with conditions; confirm the current financing and occupancy requirements from the governing documents and application instructions.

The defining feature for a buyer is the apartments themselves: because the building was adapted from two townhouses, layouts and detail vary line to line. Tour several homes to understand the range, prize the bay-windowed lines for light, and weigh the trade-off between an original-detail apartment and a renovated one. Budget for the updates that century-old systems often invite.

Lead with the building's singular story: a pre-war co-op built from two 1890s townhouses, with original bay windows, leaded glass, and mosaic detail to compare with the actual architecture and condition of purpose-built apartment houses. That character, plus the roof deck and the pet-friendly board, is exactly what the West Side character-buyer pays for — and it differentiates a listing here from the standard pre-war stock.

Because the homes are individual, presentation matters more than usual; showing original detail helps buyers evaluate the apartment but does not guarantee relative sale performance. Benchmark pricing to recent Riverside-edge pre-war co-op trades at the northern end of the corridor rather than to amenity-heavy buildings, and buyers should prepare a complete board package for a small house.
