815 Park Avenue is the second of two Rouse & Goldstone Park Avenue cooperatives on the immediate Lenox Hill corridor — the partnership's neo-Georgian commission completed three years after their Italian Renaissance palazzo at 755 Park. The 1916–1917 building, on the southwest corner of Park Avenue and East 75th Street, sits within an eight-block stretch of Park Avenue that holds two distinct Rouse & Goldstone architectural arguments executed in two distinct stylistic registers — a structural feature of the firm's work and a small architectural-history note within the broader Park Avenue corridor.
The architectural register at 815 Park is neo-Georgian — dark brown brick with the architectural restraint and classical-revival vocabulary characteristic of the Georgian Revival tradition in pre-WWI New York residential architecture. The structural distinction from 755 Park's Italian Renaissance palazzo is meaningful: Rouse & Goldstone could move fluidly between stylistic registers within the same architectural decade and the same Park Avenue corridor.
The 1989 cooperative conversion places 815 Park among the later Park Avenue conversions — a structural feature meaningful to the building's institutional cooperative history. The conversion was orchestrated by Borchard Affiliations; the building's early cooperative-era residents included Evelyn B. Metzger (artist; former Borchard president) in a 13-room apartment. Earlier historical residency (per New York Times reporting in 1927) included Peter Grimm — then-president of the Real Estate Board of New York — and E.H.H. Simmons — then-president of the New York Stock Exchange.
The combination of 46 residential apartments plus 4 professional office spaces produces a structural commercial revenue feature for the cooperative corporation, supplementing shareholder maintenance with rental income from the professional tenants.
Architecture and unit composition
The 46 cooperative apartments distribute across the building's 14 stories in configurations carrying the pre-WWI Park Avenue layout discipline. Apartment-level features documented across the building's inventory include the substantial ceiling heights, formal entry arrangements, and architectural finish specifications characteristic of 1916-1917 Park Avenue luxury construction.
Building average $/sf on recent closings has run at approximately $1,554 per public records. Recent two-year sales range has run from approximately $599,000 (1-bedroom configurations) through $3.6 million (4-bedroom configurations). ## Building operations
815 Park operates as a full-service cooperative with full-time doorman. The amenity infrastructure includes a fitness center installed in early 2011 that carries a distinctively eccentric amenity inventory — 14 fitness machines, a pool table, ping-pong, air hockey, a wet bar, and a lending library — plus private storage. The building does not carry an on-site garage, a sundeck, or sidewalk landscaping.
The cooperative policy framework — 50 percent minimum down payment, pet-friendly — supports a structurally specific buyer pool. Additional policy specifics (flip tax structure, financing maximum, pied-à-terre and sublet policies) should be verified directly during due diligence.

What to know if you’re buying
The Rouse & Goldstone neo-Georgian architectural register is structurally distinctive. The firm's stylistic versatility produced two Park Avenue commissions in two distinct registers on the same corridor (755 Park Italian Renaissance; 815 Park neo-Georgian).
The 1989 cooperative conversion is structurally meaningful. Among the later Park Avenue conversions; the cooperative culture has been continuously refined for nearly four decades.
The professional office spaces produce structural commercial revenue. The 4 commercial tenants supplement shareholder maintenance with rental income — a structural cooperative-financial feature uncommon on Park Avenue.
The eccentric fitness center amenity inventory is part of the building's identity. The 2011 installation reflects a specific cooperative cultural register that buyers should understand.
Verify operational specifics during due diligence. Specific financing maximum, flip tax structure, post-closing liquidity requirements, current capital project pipeline, and the LL11 façade cycle on the 1916–17 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 Rouse & Goldstone neo-Georgian architectural credential. A real architectural-pedigree feature within the broader Park Avenue tradition.
The professional office space income is a real cooperative-financial marketing point. The supplementary rental income is structurally meaningful to the cooperative's financial profile.
Pricing should reference recent comparable closings. The $1,554 per square foot building average provides a baseline.
Closing timelines are cooperative-standard.
