1059 Third Avenue — The Leyton — is a boutique luxury condominium that brought a tower's worth of full-floor living to a Lenox Hill corner. Completed in 2021 to a design by Manuel Glas Architects, with interiors by Champalimaud Design and Frampton Co., it was developed by Dart Interests with Real Estate Inverlad on the corner of Third Avenue and 63rd Street.
The building's calling card is its amenity program — and specifically the 24th-floor "Brandy Room," an indoor/outdoor lounge with a chalet-style fireplace, a sun terrace with an alfresco kitchen, a dining room, and a solarium, taking in Central Park, East River, and skyline views. With only 38 residences, including ten full-floor homes and a duplex penthouse, it is a small building with an outsized service offering, in the middle of the Upper East Side's shopping, dining, and transit.
Architecture and unit composition
Glas's thirty-story tower holds 38 condominium residences, weighted toward larger homes — ten of them full-floor, plus a duplex penthouse — with the contemporary glass-and-stone envelope giving upper floors long open exposures. Champalimaud and Frampton Co. interiors carry the finish level expected of a 2021 luxury condominium, with central air and in-unit laundry throughout.
The amenity package runs across two levels: a 24-hour doorman and concierge, a fitness center, a pet spa, a bike room, and a media/recreation room, capped by the 24th-floor Brandy Room.
Building operations
The Leyton operates as a staffed new-construction condominium with a 24-hour doorman and concierge. With 38 units carrying a substantial 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.

Recent sales
The Leyton trades as a condominium, so pricing is read on a price-per-square-foot basis. Sponsor sales have run since the 2021 completion, with resale activity emerging. Pricing has run in the rough range of $2,300 to $2,700 per square foot, with full-floor and duplex-penthouse homes commanding multi-million-dollar prices. With only 38 units — many of them full-floor — sales are infrequent and apartment-specific: floor, exposure, and finish drive the variation. We underwrite each unit against the building's own pricing and the Lenox Hill / Upper East Side new-development set.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01417-7502) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.
What to know if you’re buying
This is amenity-rich boutique new construction. A 24-hour doorman, two amenity levels, a pet spa, and the 24th-floor indoor/outdoor Brandy Room across just 38 units.
Many homes are full-floor. The unit mix is weighted toward larger residences; underwrite the carrying cost on the full square footage.
Underwrite a recent-construction building properly. Review financials, reserves, and any outstanding warranty or developer matters during diligence.
Condo flexibility is real. 30–45 day closings; pied-à-terre, investor, and foreign-buyer use permitted; subletting allowed under the declaration. Plan for the typical 20% minimum down.
Mansion tax cliffs apply. At these price points the $1M through $10M thresholds routinely apply — run the Mansion Tax Calculator.
What to know if you’re selling
Lead with the amenities and the full-floor format. The Brandy Room, the pet spa, and the full-floor living are the differentiators in the Lenox Hill new-development set.
Price to the building's own comps. With 38 units, the persuasive evidence is the Leyton's own pricing adjusted for floor, exposure, and finish.
Reach the global buyer. Demand for amenity-rich UES new development is international; marketing should reach cross-border as well as domestic buyers.
