49 East 21st Street is a 1913 pre-war loft building that converted to condominium ownership — an uncommon and desirable combination. Most of the pre-war loft stock on the Flatiron–Gramercy line is held as cooperative, so a condominium in an authentic century-old loft building gives buyers something rare: the soaring ceilings and oversized windows of the original commercial architecture, with the financing flexibility and ownership latitude of condominium title.
The building sits on a prime block between Park Avenue South and Broadway, steps from Gramercy Park, Madison Square Park, and Union Square, and within a short walk of some of the city's most celebrated restaurants — the kind of address where the surrounding dining, retail, and transit do as much for daily life as the apartment itself. With 43 loft residences, it is intimate, and the homes are characterful rather than uniform, each shaped by the original loft volumes and how owners have renovated them.
For buyers, the appeal is specific: authentic pre-war loft space — beamed ceilings, big light, flexible layouts — in a condominium, in one of downtown's most connected neighborhoods.

What to know if you’re selling
Lead with the rare combination: authentic pre-war loft space — beamed 11-to-13-foot ceilings, oversized windows, flexible layouts — in a condominium. That pairing differentiates a resale here from both the co-op lofts nearby and the glass new-construction condominiums in the area. Benchmark to comparable pre-war loft condominiums on the Flatiron–Gramercy line, weighting ceiling height and renovation quality. Closing mechanics are condominium-standard — a right-of-first-refusal rather than a board process — a faster, more predictable path that itself appeals to the flexibility-minded buyer this building attracts. Staging that reads the home as a true loft, and a precise comparable set, position a resale to its strength.
