109 East 79th Street is Steven Harris Architects' first ground-up Upper East Side condominium, conceived explicitly as a modern homage to the prewar Park Avenue tradition of Rosario Candela and J.E.R. Carpenter. Completed around 2020–2021 for Legion Investment Group, with interiors by Rees Roberts + Partners, it brings classically scaled layouts and an amenity program to a quiet Carnegie Hill block between Park and Lexington.
The design threads together Art Deco, Mid-Century, and Bauhaus references while organizing the apartments around the gracious-room sequencing of the prewar greats. The result is a boutique building — 31 residences across roughly 140,000 square feet — with a deep amenity roster and the kind of architectural ambition that positions it alongside Carnegie Hill's most expensive new condominiums.
Architecture and unit composition
Harris's nineteen-story building holds 31 condominium residences, from two-bedrooms up to full-floor penthouses. The Candela-inspired layouts emphasize proper foyers, separated entertaining and private wings, and well-proportioned rooms; Rees Roberts + Partners interiors carry a finish level to match, with central air and in-unit laundry throughout.
The amenity program is unusually complete for a building of this size: a double-height lobby with a 24-hour doorman and concierge, a lounge and library, a private viewing garden with a cascading fountain, a fitness center with an international squash/sports court and a yoga studio overlooking the garden, a spa with treatment rooms, a sauna, and a hair salon, plus a screening room, a golf simulator, and a game room.
Building operations
109 East 79th Street operates as a staffed new-construction condominium with a 24-hour doorman and concierge. With 31 units carrying an extensive amenity program, common charges reflect the staffing and the building's new systems. As with any recent-construction luxury condominium, buyers should review the offering plan, current financials, board minutes, and reserve study during due diligence, and confirm the status of any developer or construction-warranty matters.

Facade safety — Local Law 11
The facade passed its last inspection with no required repairs — nothing to budget for here, and no facade assessment on the horizon for roughly five years.

109 East 79th Street trades as a condominium, so pricing is read on a price-per-square-foot basis, and it prices at the top of the Carnegie Hill new-development market. Sponsor sales launched in 2020–2021, with the upper-floor and penthouse inventory commanding the marquee numbers — a penthouse reportedly traded around $35 million, with another high-floor home offered near $29 million, while mid-building residences transact in the multi-million-dollar range. With 31 highly differentiated units, sales are apartment-specific: floor, exposure, ceiling height, and finish drive the variation. We underwrite each unit against the building's own pricing and the Carnegie Hill / Upper East Side trophy new-development set.
