110 East 71st Street — The Viscaya — is a distinctive Upper East Side condominium: a set-back modern tower built in 1982 atop a retained 1916 Georgian townhouse base, on the mid-block stretch of East 71st Street between Park and Lexington. It is one of the small number of early-1980s "sliver buildings" — slim towers built on narrow lots — that prompted New York's subsequent anti-sliver zoning. The result is an unusual hybrid: a genteel redbrick townhouse street presence topped by a rounded-corner concrete tower, with a single full-floor apartment on most floors.
For buyers, the draw is the full-floor format in a genuinely boutique building. The Viscaya's 21 residences — a mix of two- and three-bedroom homes — are largely one-per-floor, each reached by a keyed elevator that opens directly into the apartment. That combination of privacy, light on multiple exposures, and full-service staffing in a small building is rare on the Upper East Side, and it defines the building's appeal to buyers who want a full-floor condominium on a prime Lenox Hill block.
Building operations
The Viscaya operates as a full-service condominium notable for delivering that service in a small building: a full-time doorman, a concierge, a live-in superintendent, a rooftop terrace, and resident storage, with the keyed-elevator full-floor format as its signature. There is no health club or gym on site — the amenity set is calibrated to a boutique building rather than a large tower.
Because the residences are deeded condominium units, ownership carries the flexibility the form implies: no cooperative board interview in the substantive sense, purchaser financing through the buyer's own lender, and pied-à-terre use, investment ownership, and subletting permitted under the condominium bylaws. The building is pet-friendly for cats and dogs, subject to approval. As with any condominium, confirm any transfer fee, the current sublet policy, the pet-approval process, and building financials against the offering plan and current house rules at offer stage.
Recent sales
The Viscaya is read on a per-square-foot basis, as all Manhattan condominiums are. Recent sales have averaged in the neighborhood of $1,700 per square foot. Two-bedroom full-floor residences have generally traded in the roughly $1.65–$2.45 million range, with three-bedroom and penthouse configurations reaching $3–$4 million. Because the building is small and largely one-apartment-per-floor, resale inventory is thin and each closing carries meaningful weight in the comparable set. Underwriting should be per-unit and floor-specific — exposure, outdoor space, and floor level drive value more than a building-wide average.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01405-7501) 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; square footage from recorded condo declarations and offering plans.
What to know if you’re buying
Buying here is a condominium path: your own financing, no substantive board approval, and use flexibility (pied-à-terre, investment, subletting) under the bylaws. The reasons to buy are specific — a full-floor residence with direct keyed-elevator access, full-service staffing in a boutique building, and a rooftop terrace, on a prime Lenox Hill block. Underwrite the specific floor and exposure carefully, confirm common charges and building financials, verify the historic-district status if façade or alteration plans matter to you, and review the pet-approval and sublet policies during due diligence.
What to know if you’re selling
The story is a full-floor, direct-elevator-access condominium with full-service staffing in a genuinely boutique building — an unusual combination on the Upper East Side. Pricing should be apartment-specific: floor level, exposure, and private outdoor space drive value, and recent comparables on the relevant configuration should anchor the number. Positioning should lead with the full-floor privacy, the keyed-elevator arrival, the rooftop terrace, and the Park-to-Lexington location, framing the building's boutique scale as a feature rather than a limitation.
