40 East End Avenue

Deborah Berke Partners designed 40 East End Avenue to sit within the East End Avenue context — a quiet residential corridor on the eastern edge of the Upper East Side, anchored by Carl Schurz Park and the East River esplanade — rather than to stand apart from it. Berke has described the aim as a building that is richly textured, with a sense of mass, while remaining very human-scaled.

The exterior is a textured charcoal-and-gray brick facade with classical ornamentation — a contemporary interpretation of the neighborhood's pre-war masonry rather than a replica of it, and a deliberate departure from the curtain-wall glass of most new construction. Casement windows and private balconies open to the family-oriented Upper East Side streetscape and, on the upper floors, to East River and Carl Schurz Park exposures. The half- and full-floor plans produce generous two- to five-bedroom apartments at the top of the contemporary East End inventory.

Deborah Berke Partners also designed the interiors. Ceilings reach roughly 14 feet, floors are white oak, and the public rooms run to a chevron-marble lobby with cerused white-oak paneling and bronze inlay and a double-height parlor lounge with a sculptural staircase. Kitchens are finished with marble slabs selected from the Apuan Alps in Tuscany, custom Italian millwork, and Gaggenau appliances; primary baths are clad in Arabescato Cervaiole marble. The result is a materially rich, tailored interior carried by a single design hand from facade to apartment.

40 East End Avenue operates as a full-service, boutique-scaled condominium. A 24-hour doorman, concierge, and full-time residential management anchor the building's operational standard, and a covered porte-cochère provides a discreet secondary entrance.

The amenity package is calibrated to the building's boutique scale rather than to the larger amenity stacks of the period's supertall towers. Second-floor amenities include a library, a game room, a fitness center, and a catering kitchen, alongside the double-height parlor lounge off the lobby. Specific amenity access, rules, and hours should be confirmed against current building materials during due diligence.

The condominium operates under standard condominium governance. Application processing for new purchasers follows the standard condominium procedural framework. Building policies on financing, subletting, pied-à-terre use, and other operational matters operate under the condominium framework with the building-specific policies set in the offering plan and the condominium's by-laws; specific policies should be confirmed against current materials during due diligence.

Market read. Most recent trades (2026) cleared a median $2,086/sf across 3 sales. Median listing discount 4.2% 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 1-01578-1307) 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 from recorded condo declarations and offering plans.

The architectural and interior-design pedigree is the structural feature. 40 East End Avenue's combination of the Deborah Berke Partners design — architecture and interiors by a single, nationally recognized firm — the textured brick facade, and the East End Avenue / Carl Schurz Park location together constitute the building's structural premium.

Apartment configurations are generous in scale. With 28 residences across 20 stories, the building runs to half- and full-floor two- to five-bedroom homes — larger configurations than the typical contemporary boutique building. Pricing requires apartment-specific comparable analysis at the apartment-line level.

The East River and Carl Schurz Park location is a substantive component of the buyer experience. The building's immediate adjacency to Carl Schurz Park (the substantial 14-acre Upper East Side park anchored by Gracie Mansion), the substantial East River esplanade, and the broader East End Avenue residential corridor produces a substantial daily-life environment substantially different from the more central Upper East Side residential inventory.

The interior-design register is a substantive value driver. Because Deborah Berke Partners designed both the architecture and the interiors, the finish program — white oak, Apuan Alps and Arabescato Cervaiole marble, custom millwork, Gaggenau kitchens — reads as a single, coherent hand rather than a developer-standard package. The interior is a substantive component of the buyer evaluation.

Financing and use flexibility is substantively greater than the equivalent uptown cooperative inventory. The condominium form supports financing percentages, holding structures, and use cases that the comparable Park-and-Fifth-Avenue tier-one cooperative inventory does not accommodate. Our Co-op vs Condo guide covers the structural distinction.

Confirm specifics directly with management. Pet policy, alteration-agreement scope, working-capital contribution, the building's current financial profile, and recent operational matters should all be confirmed against current materials during due diligence.

Marketing should foreground the architectural and interior-design distinction. 40 East End Avenue's structural premium derives in substantial part from the Deborah Berke Partners design — a nationally recognized firm's architecture and interiors under one roof — and the East End Avenue / Carl Schurz Park location. Apartment-specific marketing should foreground the specific architectural and interior-design features of the unit, the floor, the exposure, and the configuration.

Pricing requires apartment-level comparable analysis. Recent comparables on the specific apartment line, floor, and exposure should anchor the marketing approach.

The buyer pool is architecturally and East-End-residentially calibrated. 40 East End Avenue's buyer pool concentrates in the design-aware segment of the Manhattan luxury market and the substantial East End Avenue residential buyer demographic.

Board approvability is procedural at a condominium. The condominium's review of prospective purchasers is procedural rather than substantive.

Closing timelines are condominium-standard. Plan for 45–60 days from contract through closing under typical financing and due diligence circumstances.
