43 West 64th Street — Liberty Lofts — is a Lincoln Square anomaly: a genuine prewar industrial loft building half a block from both Lincoln Center and Central Park, in a neighborhood otherwise defined by prewar apartment houses and postwar towers. The building began life around 1902 as the Liberty Storage Warehouse, a heavy-masonry structure built for the kind of long-term storage that demanded fireproof construction and thick walls. The Athena Group converted it to a condominium in 2003, with Costas Kondylis adding roughly four floors atop the original eight and carving the interior into approximately 32 large loft residences.
The building's signature is the gap between what it is and where it is. Loft inventory in Manhattan concentrates downtown — SoHo, TriBeCa, Chelsea — and almost never appears in the prewar-and-tower fabric around Lincoln Center. Liberty Lofts delivers downtown loft scale (full-floor and half-floor homes with high ceilings and open plans) on a block that puts the Metropolitan Opera and the Central Park entrances within a few minutes' walk. The heavy original masonry produces exceptional soundproofing — a quiet that newer construction in the area rarely matches.
Two operational features set the building apart. Private keyed elevators open directly into the residences, giving full-floor owners a private-landing arrival; and a gated drive-through porte-cochère lets residents pull in off the street, a rarity in Manhattan that matters disproportionately to buyers who drive. The result is a boutique, low-density building — roughly 32 homes — that trades on scale, quiet, and a distinctive arrival sequence rather than a deep amenity stack.
Architecture and unit composition
The 12-story building combines the original eight-story warehouse with Kondylis's rooftop addition. Interiors are full lofts — Brazilian hardwood floors, large windows, high ceilings, and open layouts at scale, with recorded apartment sizes ranging from roughly 1,600 to over 6,100 square feet. Many residences are full-floor or half-floor; the upper floors hold multiple penthouses, two of which can combine into a triplex of roughly 6,000 square feet with more than 2,300 square feet of outdoor space.
The heavy masonry shell delivers the soundproofing and structural solidity that distinguish prewar industrial conversions from newer glass construction.
Building operations
Liberty Lofts operates as a full-service boutique condominium with a 24-hour doorman, concierge, and live-in superintendent. The standout operational features are the private keyed elevators that open directly into residences and the gated drive-through porte-cochère. The building offers private storage and a wine cellar, a fitness center, and laundry. Given the low unit count, the building's economics rest on a small owner base sharing the cost of full-service staffing — buyers should review the financials with that scale in mind.

Recent sales
43 West 64th Street prices in the high-end Upper West Side loft tier. The building average runs around $1,700 per square foot, with premium and penthouse units reaching roughly $2,500+ per square foot and whole-unit prices commonly in the $6–9 million range for the largest homes; the building-average unit value sits near $3.9 million. Because the building is small and the homes are large and idiosyncratic — full-floor versus half-floor, penthouse versus mid-floor, outdoor space or none — per-square-foot comparables must be read at the apartment level. Per-square-foot is the right metric for this condo, and the strongest anchors are recent closings on a comparable floor and configuration rather than a building-wide average.

What to know if you’re buying
You are buying a loft in a non-loft neighborhood. This is the rare full-scale prewar loft building steps from Lincoln Center and Central Park. The trade-off is a small amenity stack relative to new construction.
The masonry shell means quiet. Heavy original warehouse construction delivers soundproofing that newer buildings in the area rarely match.
The arrival sequence is distinctive. Private keyed elevators open directly into residences; the gated porte-cochère is a genuine Manhattan rarity.
The building is low-density. Roughly 32 homes; full-service staffing is shared across a small owner base. Review the financials with that in mind.
Pets are welcome. Cats and dogs are permitted.
Condominium flexibility applies. Pied-à-terre and investment use are permitted under the declaration; 30–45 day closings are typical. Confirm minimum down payment and sublet terms at offer stage.
What to know if you’re selling
The loft-in-Lincoln-Square positioning is the marketing story. Buyers seeking loft scale uptown have few alternatives.
Pricing is apartment-specific. With a small, heterogeneous stack, position against the most recent comparable-floor closings rather than building averages.
Closing timelines are condominium-fast. 30–45 days.
