The Siena is a 1996 Post-Modern condominium tower designed to complement the landmarked St. Jean Baptiste Church beside it — a red-brick building whose corner towers deliberately answer the church's bell towers rather than compete with them. Robert A.M. Stern's New York 2000 singled it out as one of the city's better Post-Modern designs for exactly that contextual restraint. It was developed by the Rose family with Daniel Brodsky and Robert Quinlan on a corner that had been a parking lot, incorporating air rights purchased from the adjacent church.
Its appeal is a full-amenity condominium package in the center of Lenox Hill. The building offers a 24-hour doorman and concierge, a fitness center with saunas, an on-site parking garage, in-unit laundry, and private storage — with the financing, resale, and leasing flexibility of condominium ownership. One block from the 77th Street 6 train and steps from Lenox Hill Hospital and Third Avenue dining, it suits buyers who want service, amenities, and condo mechanics on a prime cross-street corner.
Recent sales
The Siena trades on a price-per-square-foot basis, as condominiums do. Value here reflects the building's full amenity package — doorman and concierge, fitness center, on-site garage — its architectural quality and corner light, in-unit laundry, and the leasing and financing flexibility of condominium ownership. The thinning of the upper floors to two-apartments-per-floor and full-floor and duplex penthouse configurations creates a range of unit types and price points within one address.
Specific pricing turns on floor, exposure, layout, and finish level, with the upper-floor and penthouse units commanding a premium. Because per-square-foot values move with the market and vary by line, buyers and sellers should ground expectations in current, unit-specific comparables rather than building-wide averages.

What to know if you’re buying
- Full-amenity condo on a prime corner. Doorman, concierge, fitness center with saunas, and an on-site garage are all in the building.
- On-site parking is a genuine scarcity. A garage within the building is uncommon in Lenox Hill and adds real value.
- Architectural pedigree. The Post-Modern design and its dialogue with St. Jean Baptiste Church give the building a distinct identity.
- Understand the unit mix. Lower floors run denser; upper floors offer two-per-floor, full-floor, and duplex penthouse layouts — price accordingly.
- Budget the closing capital contribution. Purchasers pay two months' common charges at closing; confirm the current figure and any other transfer costs.
What to know if you’re selling
- Lead with amenities and parking. The fitness center, saunas, concierge, and on-site garage distinguish the Siena from thinner-amenity condos nearby.
- Market the architecture. The building's design and its contextual relationship to the church support a premium positioning.
- Match the comp to the tier. Upper-floor and penthouse units should be benchmarked against their peers, not the full building.
- Anchor to current trades. Price to recent per-square-foot sales in the building and the immediate blocks.
