1100 Park Avenue is the architecturally most eclectic pre-war cooperative on Park Avenue — and one of the only Manhattan apartment houses designed by the small Italian-American firm of DePace & Juster (Andrew DePace and Frank A. Juster). Completed in 1930 for developer Samuel Silver, the 18-story building is structurally distinct from the broader Italian Renaissance, Georgian, and neo-Venetian Gothic registers that dominated the corridor's 1920s residential building cycle.
The architectural composition at 1100 Park draws from Venetian and Romanesque ornament across a deliberately layered material palette. A three-story base of warm pink granite and sandstone supports the dark brown masonry of the upper stories. Architectural detailing includes terra-cotta ornamental balconies, Gothic-arched cornice details, and gargoyles flanking the entrance — a vocabulary that places 1100 Park outside the Italian Renaissance / Georgian house style that defined most of the 1920s Park Avenue residential mainline. The building stands out among its Schwartz & Gross / Carpenter / Candela / Blum brothers neighbors precisely because it does not follow the standard corridor architectural vocabulary.
DePace & Juster were a small Italian-American firm whose surviving Park Avenue commission is 1100 Park — an architectural-pedigree feature meaningful precisely for its structural specificity within the broader 1920s Park Avenue residential tradition. The 80-apartment scale (originally configured at 6 to 13 rooms per unit) produces a mid-size cooperative configuration with substantial apartment-level variation.
The 1955 cooperative conversion places 1100 Park among the post-war Park Avenue cooperative conversions. Many apartments retain wood-burning fireplaces; select upper-floor apartments carry private terraces.
Documented historical residency includes Prince and Princess Francis Windisch-Graetz (he a great-grandson of Emperor Francis Joseph of Austria-Hungary), who occupied a unit in 1942, and Marne Obernauer Jr. (reported in trade press as an owner of the Colorado Rockies).
Architecture and unit composition
The 80 cooperative apartments distribute across the building's 18 stories plus penthouse in configurations ranging from 6 rooms through 13 rooms per unit — a substantial apartment-level scale variation characteristic of pre-Depression Park Avenue luxury construction. Many apartments retain wood-burning fireplaces; select upper-floor units carry private terraces.
Recent transactions documented through public records include Unit 15B at $7,250,000 (September 2025; 3-bedroom, 3-bathroom configuration), Unit 3A at $8,800,018 (June 2025; 3-bedroom, 3-bathroom configuration), Unit 7A at $3,300,000 (April 2024; 2-bedroom, 2-bathroom configuration at approximately 2,200 square feet), and Unit 7AA at $1,200,000 (April 2024; 2-bedroom, 2-bathroom configuration on the smaller line).
Building operations
1100 Park operates as a full-service cooperative with 24-hour doorman and live-in superintendent. The building's recently renovated lobby anchors the contemporary architectural presentation; the amenity infrastructure includes a fitness center, bike storage, and private storage.
The cooperative policy framework — 50 percent maximum financing, 2 percent buyer-paid flip tax, pet-friendly — supports a structurally specific buyer pool. Pied-à-terre allowance and sublet specifics should be verified directly with management.
What to know if you’re buying
The architectural composition is structurally distinguishing. The Venetian-Romanesque eclectic register is outside the Italian Renaissance / Georgian mainline; the building stands out architecturally within the broader Park Avenue corridor.
The DePace & Juster architectural pedigree is structurally specific. Among the few Manhattan apartment houses designed by the firm; 1100 Park is the firm's surviving Park Avenue commission.
Wood-burning fireplaces are real apartment-level features. Many apartments retain operational fireplaces — uncommon among contemporary Park Avenue cooperative inventory.
Private terraces on select upper-floor units are structural. Apartment-level outdoor space uncommon on Park Avenue cooperative inventory.
The recently renovated lobby is real. Contemporary capital project work at the building.
The Park Avenue Historic District protection applies. Designated LP-2547 by the NYC LPC on April 29, 2014.
Apartment configurations span 6 to 13 rooms. Substantial scale variation; recent comparable analysis depends on the specific configuration.
Verify operational specifics during due diligence. Specific board approval framework, sublet duration limits, current capital project pipeline, and the LL11 façade cycle on the 1930 vintage should be reviewed.
Closing timelines are cooperative-standard. Plan for 6–10 weeks from contract through board approval to closing.
What to know if you’re selling
Marketing should emphasize the architectural distinctiveness. The Venetian-Romanesque register, the gargoyles at the entrance, the pink-granite-and-sandstone base, and the wood-burning fireplaces are real architectural features that distinguish the building from peer Park Avenue cooperatives.
The DePace & Juster architectural credential is a real marketing point. Specific to the building within the broader Park Avenue corridor.
Pricing should reference recent comparable closings. The $8,800,018 June 2025 closing on Unit 3A provides recent upper-tier reference; the building's substantial apartment-line variation produces meaningful pricing differentiation.
Closing timelines are cooperative-standard.
