The Frost House (1156 Third Avenue)

The Frost House is a white-brick composition of the mid-1960s — a clean, unadorned postwar tower whose most recognizable exterior feature is the polished black-granite surround at the Third Avenue entrance. Many apartment lines carry private balconies, a hallmark of the balcony-forward towers built along Third Avenue in that decade, and the ground floor carries a Third Avenue retail base.

The roughly 163 residences run from studios and one-bedrooms through larger multi-bedroom homes, several of which have been combined over the years into three- and four-bedroom layouts. Higher floors and balcony lines command the strongest light and the most open exposures; buyers should price the specific line and floor rather than a building-wide average. Finishes vary widely apartment to apartment — original 1965 kitchens and baths in some, full gut renovations in others — so per-square-foot value tracks condition as much as position.

The Frost House operates as a full-service condominium: a 24-hour doorman, a live-in resident manager, a renovated lobby, basement laundry, and bike storage. The amenity plant is deliberately lean — this is a doorman-and-service building rather than a pool-and-club tower — which keeps common charges more moderate than the corridor's heavier-amenity peers. Buyers should confirm the specific unit's common charge and property-tax carry, review the reserve position and any active assessment during diligence, and verify the current house rules, since a mid-1960s building of this size carries an ongoing capital-maintenance program for its façade, balconies, and building systems.

Market read. $/sf is measured on the latest sales with reliable square footage (2024): a median $926/sf across 1 sale. The building has traded as recently as 2026. Median listing discount 3.3% 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 1-01402-7501) 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.

Price per foot, but price the line. In a large tower, per-square-foot value tracks floor, exposure, balcony access, and renovation condition. A high-floor balcony line and a low-floor interior line are different markets. Model the specific apartment, not the building average.

Confirm the carry and the reserves. The lean amenity plant keeps common charges moderate, but a mid-1960s building runs an ongoing capital program. Confirm the unit's common charge and tax carry, the reserve position, and any assessment. Run the True Monthly Carrying Cost Calculator.

Condo flexibility is real. Pied-à-terre and investment use, subletting, and financing without a co-op board's thresholds are generally available under the declaration — a meaningful contrast to the surrounding co-ops. Confirm the current sublet and pied-à-terre policy in the house rules at offer stage.

Check the pet policy. Cats are permitted; dogs are generally not. If a dog is part of the household, verify the current house rules before you commit.

The location is central. Steps from the Lexington line, crosstown bus service, and the Third Avenue retail spine — a more central position than the corridor's river-edge towers. Weigh that against the amenity-heavier buildings nearby.

Lead with balconies and staff. Private outdoor space and a full-time doorman are the marketing headline on this stretch of Third Avenue. Show the balcony and the light.

Sell the flexibility. The condominium structure — subletting, pied-à-terre and investor use, and financing without a co-op board's thresholds — widens the buyer pool relative to the neighboring co-ops. Market to it.

Position condition and per-foot value. Renovated and combined apartments trade on their own comparable set; price the specific line and finish level, not a tower average, and frame value per square foot.

Closing timelines are condo-fast. 30–45 days from contract to closing; foreign and investor buyers are welcome under the declaration.

The Roebling Team at Compass works Lenox Hill and the Third Avenue corridor of the Upper East Side as a core practice area. We publish this profile because a large full-service tower demands unit-level, per-square-foot analysis — the specific line, the balcony, the condition, and the carry math, not a blended building average.
