The Kingsley is a 40-story, 216-unit condominium at First Avenue and 70th Street, built in 1984 by developer Ian Bruce Eichner to a Stephen B. Jacobs design notable for its bold stepped massing and rounded balconies. Its signature amenity choice is architectural: the developer placed the fitness center on the 31st floor, with panoramic views and two outdoor terraces, rather than in the base — turning a standard amenity into a skyline experience and giving the building a distinctive identity in the corridor.
Built during the mid-1980s condominium boom as new construction rather than a conversion, The Kingsley offers the transactional flexibility the corridor's cooperative inventory does not: no co-op financing cap, permitted pied-à-terre use, sublets allowed with approval or notice, and condo-fast closings. The full-service baseline — 24-hour doorman and concierge, live-in resident manager, laundry on every floor, direct-access parking garage, bike room, storage, and a residents' lounge — rounds out the offering.
Two honest notes for buyers. First, the building enforces a strict no-pets policy, which is more restrictive than most corridor condominiums and a threshold consideration for pet owners. Second, a building-wide assessment has been in place through April 2026; buyers should confirm its current status and any successor assessment during diligence.
Architecture and unit composition
The 216 residences distribute across the tower's 40 stories in layouts that run from studios through two-bedroom and larger homes, with many units carrying terraces or the building's signature rounded balconies. South and west high-floor exposures are prized for evening light and views. Interior finish quality varies across the inventory; apartment-level diligence is the right reference for any given line and floor.
Jacobs's stepped massing gives the building a sculpted profile on the First Avenue frontage, and the rounded balconies are its most recognizable feature.
Building operations
The Kingsley operates as a full-service condominium with a 24-hour doorman and concierge and a live-in resident manager. The 31st-floor fitness center with its two terraces is the amenity centerpiece, supported by laundry on every floor, a direct-access public parking garage, a bike room, luggage and resident storage, a residents' lounge, and a courtyard.
Two operating points matter for diligence: the strict no-pets policy and the building-wide assessment in place through April 2026. Buyers should confirm the assessment's current status, model the full carry, and review the building's financials and reserve position during due diligence.

Recent sales
The Kingsley trades as a full-service Lenox Hill condominium. Recent closings have run broadly in the $1,237 per square foot range on a building-wide basis, with asking prices somewhat higher; absolute pricing spans from smaller one-bedrooms in the mid-to-high $600,000s to larger high-floor two-bedrooms above $3 million. High-floor south and west exposures carry the premium.
Pricing is heterogeneous by floor, exposure, and layout, and the assessment is a live variable in the near-term carry. Comparable analysis should reference recent closings on the specific line and floor rather than a single building-wide average.

What to know if you’re buying
The 31st-floor gym is a distinctive draw. A high-floor fitness center with panoramic views and two terraces is a genuine differentiator.
Condominium flexibility applies. No co-op financing cap, pied-à-terre permitted, sublets allowed with approval or notice, and condo-fast closings.
The strict no-pets policy is a threshold consideration. Confirm before proceeding if you have or plan to have a pet.
Confirm the assessment status. A building-wide assessment has been in place through April 2026; verify its current standing and any successor.
What to know if you’re selling
Lead with the high-floor gym and the balconies. The 31st-floor fitness center and the signature rounded balconies are the building's most marketable features.
Address the assessment proactively. Buyers will ask; have the current status ready.
Price at the line and floor. Exposure and floor drive meaningful variation; reference the specific line's comparables.
