The Crown Building / Aman New York Residences (730 Fifth Avenue)

The original 1921 Warren & Wetmore tower is a Beaux-Arts landmark, its gilded crown a century-old fixture of the Fifth Avenue skyline. The conversion preserved the building's landmark exterior while reconstructing the interior into a hotel-and-residential program, with the 22 condominium residences occupying the upper floors above the Aman hotel.

The residences are large by Manhattan standards — averaging well over 4,000 square feet — befitting a building positioned at the apex of the luxury market. Layouts, exposures, and view altitude vary by floor; the upper-floor residences command Central Park, Fifth Avenue, and skyline sight lines. As with any trophy building, each residence should be evaluated on its own configuration, exposure, and finish level.

The Crown Building operates as an ultra-luxury condominium above the Aman New York hotel. Resident services draw on the hotel's full infrastructure: the three-floor Aman Spa with its 67-foot indoor pool, the private Members Club, restaurants, a sky lobby, and dedicated residential elevators with direct access to the hotel, spa, and club. The private residential entrance on West 56th Street separates resident arrival from hotel traffic.

As with any mixed-use condominium of this kind, the allocation of operating costs between the residential and hotel components, the resident-service program, and the house rules are governed by the condominium documents. Prospective buyers should review the offering plan and amendments, the most recent condominium financial statements, the budget and reserve picture, any board minutes, and any active litigation during due diligence. Carrying costs — common charges, property taxes, and any service-program fees — are substantial at this tier and should be modeled in full.

Recent closings at this building, curated by The Roebling Team research desk. Apartment-level facts are independently verified before publishing; sale prices reflect the recorded transfer amount at the NYC Department of Finance.

Market read. Most recent trades (2026) cleared a median $5,909/sf across 2 sales. Median listing discount 14.0% 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 1-01272-7503) 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.

You are buying a service experience and a landmark. The Aman program — spa, pool, Members Club, restaurants, and hotel-grade service — is the central proposition, alongside one of the most recognizable addresses in Manhattan. If you want a strictly residential building, the trophy condominiums of Billionaires' Row offer pure-residential alternatives.

Model the full carry. Common charges, property taxes, and any service-program fees are substantial at this tier. Underwrite the complete monthly cost before you make an offer.

Condo flexibility is real. Expect 30–45 day closings, foreign-buyer acceptance, and pied-à-terre, investment, and sublet use permitted under the declaration.

Diligence on the conversion applies. Review the offering plan, condominium financials, reserve study, and any active litigation. The Roebling Report's coverage of construction and conversion risk in The Cracks in a $90M Penthouse frames the diligence questions that apply to any recent high-end conversion.

Mansion tax cliff effects are major. At this building's pricing, multiple cliff thresholds apply. Run pricing through the Mansion Tax Calculator.

Marketing requires global reach. The buyer pool is international; access to global broker networks is material to selling at this building's price points.

The Aman program is the marketing story. The spa, pool, Members Club, and hotel-grade service — alongside the landmark address — are the building's defining differentiators and should anchor the presentation.

Pricing requires residence-level context. With only 22 residences, comparables are scarce and heterogeneous; view altitude, exposure, floor, and finish all drive pricing. In-building history, carefully adjusted, is the strongest evidence.

Closing timelines are condo-fast. 30–45 days from contract to closing.

We publish this building profile because trophy buyers and sellers deserve building-specific intelligence — the architecture and landmark history, the operational reality of a hotel-and-residential program, the transactional mechanics, and pricing read at the residence level — not generic market commentary.
