135 East 54th Street (The Lex 54 Condominium)

The building rises 16 stories in post-war brick along a 146-foot blockfront at the Lexington corner. The massing is conventional but the details reward attention: the top five floors carry terraces, several upper lines wrap the corner, and the rooftop watertank enclosure — highlighted by five thin steel bands — gives the building its modest skyline signature, per architectural records. The second floor is given over to commercial and professional space (the offering plan's professional unit comprises five offices plus the superintendent's apartment), and eight retail stores line the base.

The 141 residences per the offering plan run from studios through one- and two-bedrooms to three-bedroom combinations, at roughly nine to ten units per floor. Layouts are post-war practical — central foyers, defined kitchens, generous closets — and the marquee inventory is the terrace stock above the 12th floor, including a documented three-bedroom with a wraparound terrace accessible from four rooms. Architectural records note the building permits protruding window air-conditioners; buyers expecting central systems should calibrate, and renovators should confirm current HVAC policy with the managing agent.

Full-service at the essentials: 24-hour doorman, live-in superintendent, central laundry, bike room, storage, and a package room, with the lobby, hallways, and elevators renovated in recent cycles per listing records. This is a service building rather than an amenity building — no gym, pool, or roof deck is documented. The commercial and professional units are owned by entities unrelated to the residential ownership, per the amendments on file, so the residential condominium neither controls nor depends on the retail below — a structural point worth understanding during diligence. The offering plan, amendments, and audited financial statements are on file in The Roebling Research Library.

Recent sales

Recent closings at this building, curated by The Roebling Team research desk. Apartment-level facts are independently verified before publishing; sale prices reflect the recorded transfer amount at the NYC Department of Finance.

Market read. Most recent trades (2026) cleared a median $993/sf across 2 sales. Median listing discount 3.9% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01309-7502) 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.

The condo framework is the product. No board interview, documented sublet terms (six-month minimum, two-year maximum per listing records), and pied-à-terre flexibility — at this price tier, that combination is what separates the Lex 54 from the surrounding post-war co-op stock. Investors and parents buying for family should confirm current policy specifics with the managing agent.

Underwrite it like the mixed-use building it is. The retail and professional units are separately owned. Your attorney should review how expenses allocate across the residential, commercial, and professional units in the by-laws — the documents are on file with us.

The governance record is long and legible. Forty-seven-plus amendments, audited financials, and resident board control since 1987 make this one of the better-documented conversions of its era. Use that: the paper trail answers most diligence questions before they're asked.

Buy the line, not the building average. Terraced upper-floor corner units and compact mid-floor studios are different products under one roof. Same-line history matters more here than building-wide $/sf.

Calibrate on systems and noise. A 1951 building at a major Lexington intersection means window air-conditioners per architectural records, and avenue-side sound on the east exposures. Spend time in the specific unit at rush hour before offering.

Lead with the attribution, carefully. "Candela-attributed post-war" is a real differentiator in a corridor of anonymous towers — but state it as the architectural records do, and let the foyers and closets make the argument in person.

Market to both buyer pools. End-users want the doorman, the location, and the terrace stock; investors want the sublet framework and the rental comparables. The marketing should speak both languages, with the policy facts stated plainly.

Price against the condo set, not the co-op set. Your competition is the 1980s and post-war condo inventory of Midtown East — not the co-ops next door, whose pricing reflects board friction the Lex 54 doesn't have.
