249 East 62nd Street (The Treadwell)

The 66 residences distribute across the tower at two to four homes per typical floor, which is a low density for a building of this height and produces a high proportion of corner and through-floor layouts relative to a conventional 10-unit-per-floor plate. The mix runs studios through three-bedrooms, with a penthouse tier carrying private terrace.

The exterior specification is the argument. Fluted terracotta panels — a masonry cladding rather than a rainscreen imitation of one — frame floor-to-ceiling window openings with bronze-toned mullions, and the vertical rib pattern gives the shaft a pre-war reading from the street despite the contemporary glass area. Projecting balconies with glass railings run the tower floors; they are the most-debated element of the design in architectural commentary, which has generally admired the terracotta and the crown while questioning whether the balconies compete with them. The crown itself is composed of stacked, interlocking volumes with rounded corners, lit at night — a deliberate Art Deco citation.

Interiors were conceived alongside the exterior rather than after it, with model residences designed by Billy Cotton. Residences carry floor-to-ceiling glazing, in-unit washer/dryer, and the deep-window reveals the terracotta frame produces.

The Treadwell operates as a full-amenity new-construction condominium with an on-site superintendent and an attended double-height lobby. The amenity program is consolidated on the first two levels rather than dispersed: fitness center, sauna and steam room, children's playroom, residents' lounge, meeting rooms, a private landscaped courtyard, and a meditation garden. For a 66-unit building that is a generous ratio of amenity square footage to residence, and it is worth weighing against the common charge — small buildings carry amenity operating cost across few units.

Two operating items deserve attention at diligence. First, the concierge-medicine and curated-experience memberships offered at launch were sponsor inducements tied to sponsor closings; they should not be assumed to run with the unit on resale. Second, as a building completed in 2024, The Treadwell is early in its capital life and its reserve position and first full-year operating budget are still being established. Ask for the current audited financial statements, the current budget, and the sponsor's remaining unsold inventory, which in a 66-unit building can materially affect both voting control and the practical liquidity of the resale market.

Ownership form: Condominium. The board's transfer right is a right of first refusal, not a cooperative-style approval — closings are faster and the buyer pool is wider than at the surrounding Lenox Hill cooperative inventory.

Pied-à-terre, LLC, trust and foreign ownership: Permitted under the standard condominium framework. This is the structural difference that matters most in this corridor, where most of the competing inventory is cooperative and restricts all four.

Subletting: Permitted. Minimum lease term and any board notification requirement should be confirmed with the managing agent.

Financing: No board-imposed financing ceiling. Standard condominium lending applies.

Flip tax / working capital: Not documented in public records. New-development condominiums commonly charge a working-capital contribution — typically expressed as a multiple of monthly common charges — at sponsor closing, and sometimes at resale. Confirm against the offering plan.

Property taxes: Buyers should model the tax line carefully. A 2024-completion building's assessment can move sharply in its first full assessment cycles, and any abatement position should be verified against the current Department of Finance bill for the specific unit rather than assumed from a marketing sheet.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026) cleared a median $2,130/sf (floor-adjusted) across 4 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 0.0% from the last ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01417-7503). 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 from recorded condo declarations and offering plans.

The entitlement history is a feature, not a footnote. The lot's height was litigated in public through DOB challenges, an FDNY referral, elected-official intervention, and a zoning text amendment. The building that stands was built under the amended rules. That is a cleaner entitlement record than most new construction offers.

It is next to the historic district, not in it. The Treadwell Farm Historic District begins immediately west. Being outside it is why the tower exists; being beside it is why the mid-block row-house streetscape on 61st and 62nd is protected and will not be redeveloped. Both facts are worth to a buyer.

Verify the floor count against the offering plan. Marketed as 28 stories; city records carry 26. For a specific unit, the plan and the certificate of occupancy govern.

Model the tax line, not the marketing line. A 2024-completion building is early in its assessment history. Run True Monthly Carrying Cost against the actual current bill.

Ask about remaining sponsor inventory. In a 66-unit building, sponsor-held units affect both board control and resale liquidity.

Lead with what is scarce. New-construction condominium form, full amenity floor, in-unit laundry and floor-to-ceiling glass are all uncommon in Lenox Hill's competing inventory. The comparison set for most buyers is a cooperative that permits none of the things a condominium permits.

The architecture is marketable and specific. Fluted terracotta, bronze mullions, an Art Deco crown, and an interior program by a named designer — the building has a design story that can be told precisely rather than generically.

Price to the line, not to the building. With two to four homes per floor, building-average per-square-foot figures are noisy. Same-line and adjacent-floor comparables are the honest anchor.

Address the sponsor overhang directly. If unsold sponsor inventory remains, price and position against it rather than around it.
