911 Park Avenue — The Alvarado — sits at the western anchor of one of the most architecturally significant side-street blocks in Manhattan: a stretch of East 80th Street containing the George Whitney mansion, the William Goadby Loew mansion, and several other landmark houses that produce a structurally protected architectural setting east of Park Avenue. The 1927 Schwartz & Gross commission for Tishman positions The Alvarado at the western end of this institutional architectural corridor and within the broader Park Avenue Historic District.
Schwartz & Gross was the most prolific Park Avenue architect of the 1920s. The firm's Park Avenue body of work includes 470, 525, 885, 888, 910, 930, 941, 970, 983, 1045, 1070, 1125, and 1165 Park — a concentrated single-firm body of work that defined a substantial share of the corridor's residential architectural character. The Alvarado is one of the firm's more disciplined classical compositions: a two-story limestone base with a canopied entrance flanked by fluted pilasters, three stringcourses, and quoins. The architectural composition is consistent with Schwartz & Gross's broader mid-1920s classical vocabulary.
The 1952 cooperative conversion places The Alvarado among the earlier post-war Park Avenue cooperative conversions. The 44-apartment scale produces a mid-size cooperative configuration with substantial apartment-level scale variation.
Architecture and unit composition
The 44 cooperative apartments distribute across the building's 14 stories in substantial configurations. The Alvarado is documented for the size of its apartments: many exceed 4,000 square feet. Apartment-level features include wood-burning fireplaces, 10-foot ceilings (11 feet in the penthouse), herringbone floors, crown moldings, and coffered ceilings.
The floor plans are deeply pre-war Park Avenue. Apartment 11A carries a 28-foot entrance gallery; Apartment 4B carries a 23-foot foyer leading into a 23-foot library, then a 16-foot gallery, then a 25-foot living room. Apartment configurations include oversized living rooms facing Park, formal dining rooms, butler's pantries, and dedicated staff wings.
Recent CityRealty-documented sales include Unit 6B at $7,250,000 (5-bedroom configuration) and Unit 11C at $5,950,000 (4-bedroom configuration), both transactions from the 2024–2025 cycle.
Building operations
The Alvarado operates as a full-service cooperative with full-time doorman and private storage. The building does not carry an on-site garage, fitness center, or roof deck — the operational baseline is conservative even by Park Avenue cooperative standards and reflects the building's institutional pre-war tradition.
Specific cooperative policy details (financing maximum, flip tax structure, pet policy, pied-à-terre allowance, sublet duration limits) should be verified directly with management.
What to know if you’re buying
The Schwartz & Gross architectural pedigree is real. Among the firm's mid-1920s Park Avenue commissions; the architectural composition is consistent with the firm's broader Park Avenue body of work.
The East 80th Street institutional architectural context is structural. The George Whitney mansion, the William Goadby Loew mansion, and the broader East 80th Street side-street architectural concentration produce a structurally protected setting east of Park Avenue at The Alvarado's corner.
Apartment scale is substantial. Many apartments exceed 4,000 square feet; 28-foot entrance galleries, oversized living rooms, formal dining rooms, butler's pantries, and dedicated staff wings characterize the apartment idiom.
The Park Avenue Historic District protection applies. Designated LP-2547 by the NYC LPC on April 29, 2014.
The operational baseline is institutional. Conservative amenity inventory by Park Avenue standards; the cooperative culture reflects the building's institutional pre-war tradition.
Verify operational specifics during due diligence. Specific board approval framework, financing structure, flip tax, sublet duration limits, current capital project pipeline, and the LL11 façade cycle on the 1927 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 Schwartz & Gross credential and the East 80th Street architectural setting. Both are structural identity features.
Apartment scale supports premium positioning. The 4,000-plus-square-foot apartment configurations are real architectural assets within the broader Park Avenue cooperative tier.
Pricing should reference recent comparable closings. The Unit 6B $7,250,000 and Unit 11C $5,950,000 closings provide recent upper-tier reference; apartment-line-specific comparables should anchor positioning.
Closing timelines are cooperative-standard.
