530 Park Avenue is one of the most architecturally interesting and operationally distinctive condominium conversions on Park Avenue south of 79th Street. The building's structural identity rests on three features that together produce a substantively different ownership profile from peer Park Avenue inventory.
First, the late-prewar / Art Deco architectural composition by George F. Pelham Jr. — the architect whose Manhattan portfolio also includes 41, 50, 785, 1130, and 1150 Park Avenue plus 1056 Fifth Avenue, a major but less-celebrated figure in the late-prewar canon than Candela or Cross & Cross. The 1940 vintage places 530 Park at the tail end of the prewar Park Avenue construction cycle, just as steel allocation shifted to wartime priorities. Second, the Aby Rosen / RFR Holding 2013 conversion by Handel Architects with interiors by William T. Georgis — a comprehensive redesign of the lobby into a grand double-height ribbed limestone entrance rotunda with Nordic Gray and Cold Spring granite floor, ebonized wood concierge desk, a sitting room overlooking the garden, a media center, and a dark wood-paneled library with billiard table. Third, the Sant Ambroeus catering / room service amenity — the Milanese restaurant with locations on Madison Avenue and at the adjacent Regency Hotel — a distinguishing feature uncommon among peer Park Avenue condominiums.
The location is among the highest-scored on Park Avenue. CityRealty's Location score of 29/36 — among the highest on the corridor — reflects the building's adjacency to the Regency Hotel, Madison Avenue retail, Central Park, and the 59th and 63rd Street subway hubs.
Architecture and unit composition
The 19-story white-brick building at 530 Park Avenue was erected in 1940 at the tail end of the prewar Park Avenue construction cycle. It was designed by George F. Pelham Jr., whose Manhattan prewar portfolio includes 41, 50, 785, 1130, and 1150 Park Avenue and 1056 Fifth Avenue. Carter Horsley's CityRealty review describes the defining architectural features as "two piers of curved glass bay windows flanking Juliet balconies above its entrance on the avenue" and a "very handsome, ribbed, two-story limestone base" with sidewalk landscaping.
The building is also known as 48-60 East 61st Street. Pelham Jr. designed it on a generous L-shaped footprint that wraps the southwest corner of 61st and Park — the corner site immediately south of the Regency Hotel and the Christ Church United Methodist by Ralph Adams Cram on the north side of 61st.
The building's commercial-residential rental life ran for 67 years, from 1940 to 2007. In 2007, BlackRock Realty Advisors paid approximately $211 million for the building. The 2008 financial crisis paused the conversion plan. Aby Rosen / RFR Holding entered a joint venture with the existing ownership in August 2010 to complete a for-sale condominium conversion. RFR submitted the conversion plan within months. The conversion preserved the prewar masonry envelope while comprehensively redesigning the lobby and interior infrastructure.
Apartment-level finishes include kitchens with Smallbone of Devizes cabinetry, Pietra Cardosa Italian granite, Sub-Zero refrigeration, Wolf ranges, Bertazzoni ovens, and Viking hoods. Bathrooms feature Crema Marfil marble walls, wood-grain brown marble floors, Kohler Caxton sinks, Toto toilets, and radiant heating in the primary bath. Units carry in-unit Bosch washer/dryers and individually controlled HVAC.
Carter Horsley's bottom line: "very prime location on Park Avenue with some curved glass windows, a limestone rotunda entrance and catering by Sant Ambroeus."
Building operations
530 Park operates as a full-service condominium with the following operational baseline:
- 24-hour doorman and concierge
- Live-in superintendent
- Catering and room service by Sant Ambroeus — a distinguishing amenity uncommon among peer Park Avenue condominiums
- Landscaped courtyard with French garden and black-tile reflecting pool designed by Town & Gardens Ltd, with gravel walkways, blue stone pavers, and a privacy wall of English ivy with red maple trees
- Private fitness center overlooking the courtyard
- Library with billiards table
- Children's creativity center
- Bicycle storage, central laundry, resident storage
- No roof deck; no balconies (Juliet only); no on-site garage
- In-unit Bosch washer/dryer; individually controlled HVAC
The Sant Ambroeus amenity is structurally distinguishing. Resident access to room service and catering from one of Manhattan's most established Milanese restaurants is uncommon at the condominium level along Park Avenue.
Recent sales
CityRealty (February 11, 2026 last update) reports active inventory of 4 apartments for sale (average $2,739/sf), 1 for rent (average $160/sf), and 13 recent closings (average $2,113/sf). Apartment-level closing detail should be sourced from NYC Department of Finance recorded transfers (BBL 1-01376 series) at production time for full transactional context.
What to know if you’re buying
The condominium structure is the largest single competitive advantage. Pied-à-terre, subletting, LLC ownership, trust ownership, and foreign-buyer eligibility are all permitted under the declaration — a profile uncommon along Park Avenue south of 79th Street.
The Sant Ambroeus catering and room-service amenity is structurally distinguishing. Resident access to one of Manhattan's most established Milanese restaurants is rare at the condominium level along the corridor.
The 2013 conversion produced fully modern interior infrastructure. Smallbone kitchens, Sub-Zero / Wolf appliances, marble bathrooms, in-unit washer/dryers, and individually controlled HVAC are uniform across the inventory.
The location score is exceptional. CityRealty's 29/36 Location score is among the highest on Park Avenue, reflecting Regency Hotel adjacency, Madison Avenue retail, Central Park, and 59th and 63rd Street subway access.
The Pelham Jr. architectural pedigree is real. The architect's broader Park Avenue and Fifth Avenue portfolio (41, 50, 785, 1130, 1150 Park; 1056 Fifth) represents a substantial late-prewar body of work.
The Aby Rosen / RFR Holding sponsor credibility is real institutional context. The conversion was executed by one of New York's most established developer-investors.
Verify the right-of-first-refusal mechanics during diligence. Condominium ROFR is rarely exercised but the declaration mechanic should be reviewed.
Closing timelines are condominium-standard. Plan for 30 to 45 days from contract through ROFR waiver to closing.
What to know if you’re selling
Marketing should emphasize the condominium policy flexibility and the Sant Ambroeus amenity. Both are structural advantages over peer Park Avenue cooperative inventory.
The Pelham Jr. + Handel Architects + Aby Rosen credential layering is real institutional context. The combination of late-prewar architecture, top-tier 2013 conversion architecture, and Rosen sponsor credibility supports premium positioning.
The 81 CityRealty rating with the 29/36 Location score is marketable. Cite the rating in positioning materials.
Pricing should reference the $2,113/sf average closing price across the 13 recent CityRealty-tracked closings. Apartment-line-specific comparables should anchor positioning.
Closing timelines are condominium-standard.
