The Astor at 235 West 75th Street is one of the Upper West Side's most consequential pre-war buildings — and one of its most interesting modern conversion stories. William Waldorf Astor commissioned the original building from Clinton & Russell in 1900–1901, with a third tower added in 1914–1915 by Peabody, Wilson & Brown. For more than a century it was a rental and, at points in its mid-century life, a single-room-occupancy building. A gut conversion in 2014–2015 — developed by HFZ Capital Group with interiors by Pembrooke & Ives — relaunched it as The Astor, a condominium.
The architecture is the headline. The building is a textbook Beaux-Arts / Renaissance Revival composition: rusticated grey brick over a limestone base, splayed window lintels with scroll keystones, gracefully rounded limestone corners, and a projecting copper cornice, all organized as a multi-tower block that fronts Broadway. The Landmarks Preservation Commission included it as a contributing building — "Astor Court" — in the West End–Collegiate Historic District Extension in 2011, which protects the façade and anchors the building's permanence.
The conversion turned that landmark shell into modern condominium homes. For buyers, the proposition is rare: genuine pre-war Astor-era architecture with a contemporary, fully renovated interior program and the transactional flexibility of condo ownership.
Architecture and unit composition
The Astor's residences run large. The bedroom mix skews to two- through five-bedroom layouts, with studios and one-bedrooms scarce; apartments span roughly 1,500 to 3,000 square feet, and the conversion delivered the high ceilings, oversized windows, and proportions of the original Astor-era plans within fully rebuilt interiors.
The Pembrooke & Ives conversion specified a high contemporary finish — open kitchens, restored or recreated period detail at the public spaces, and in-unit washer/dryer in many homes. Penthouse-level residences carry private terraces. Because the building is a conversion of a complex multi-tower structure, layouts vary meaningfully by line and tower; buyers should evaluate exposure, light, and floor on an apartment-by-apartment basis.
Building operations
The Astor operates as a full-service pre-war condominium with a 24-hour doorman and concierge, a live-in resident manager, and elevator service. Shared amenities include a fitness center, a children's playroom, a bike room, private storage, central laundry, and a private landscaped garden overlooking Broadway — a service-and-amenity package consistent with a high-end converted landmark.
Pets are welcome — dogs and cats are permitted. As a condominium, the building offers the flexibility owners value: pied-à-terre ownership and investor purchases are permitted, and subletting is allowed under the declaration, subject to a building right of first refusal on transfers. Specific board financial policy and current sublet terms should be confirmed at offer stage.

The Astor prices as a premium converted-landmark condominium. With its large-apartment inventory, the building transacts on a price-per-square-foot basis in the upper range for the Broadway corridor — generally on the order of roughly $1,800 to $2,100 per square foot, varying by tower, line, floor, and condition. Larger four- and five-bedroom homes and penthouse-level residences with private outdoor space anchor the building's top end.
Turnover is moderate for a building of roughly 98 units. Building-wide averages mask wide variation across the multi-tower plan; a current apartment-level comparable analysis is the right tool for pricing any individual residence.

What to know if you’re buying
You're buying landmark architecture with a modern interior. The Astor delivers genuine 1901 Astor-era Beaux-Arts character behind a 2015 gut renovation — a combination that is hard to replicate.
The inventory is large and family-oriented. Two- through five-bedroom homes dominate; this is a primary-residence building first.
Condo flexibility applies. Pied-à-terre, investor ownership, and subletting are permitted, subject to the building's right of first refusal; financing is condo-standard.
Evaluate by tower and line. The multi-tower plan produces meaningful variation in exposure and light.
Mansion tax applies. Run pricing through the Mansion Tax Calculator.
What to know if you’re selling
Lead with the Astor pedigree and the landmark façade. The 1901 Clinton & Russell authorship and the West End–Collegiate designation are genuine differentiators.
Foreground the conversion quality and the amenities. The Pembrooke & Ives interiors, the garden, and the full-service staff widen the buyer pool.
Differentiate by tower, exposure, and outdoor space. Penthouse-level homes with terraces warrant bespoke positioning.
Closing timelines are condo-fast. Generally 30–45 days from contract to closing.
