Description

Meet The Maisonette.

A dramatic duplex loft with the privacy and presence of a townhouse, The Maisonette at 29 West 21st Street is a rare downtown residence in the heart of Flatiron—pairing grand proportions, authentic loft character, and a secluded outdoor retreat within an intimate six-residence boutique condominium.

Entered directly from the building lobby, The Maisonette opens into an expansive living and entertaining space with soaring ceilings reaching approximately 12 feet. Wide-plank smoked Austrian oak floors extend toward oversized matte-black steel casement windows, while exposed brick, wood-paneled walls, and thoughtfully integrated cove lighting bring warmt
h and texture to the home’s industrial architecture.

At the center of the loft, the open kitchen is both refined and functional, with premium appliances seamlessly incorporated into custom, locally milled cabinetry. Generous proportions allow living, dining, and entertaining to coexist effortlessly, while a powder room provides convenience for guests. The scale of the main living area also allows for a convertible three-bedroom configuration, offering additional flexibility to accommodate evolving lifestyle, household, or guest needs.

An architectural wraparound staircase leads to the private lower level, where spacious and serene bedrooms feature en-suite baths, generous closet space, and radiant floor heating. Each bedroom opens directly onto a secluded rear patio framed by high brick walls—an unexpected private refuge from the energy of the city. A flexible den or home office provides additional space to work, unwind, or host.

The residence is completed by a private laundry room with deep sink and linen storage, central air conditioning, oversized windows, and discreet 24-hour remote monitoring with virtual lobby attendant and secure package delivery.

Set within a landmarked 1909 Renaissance Revival building in the Ladies’ Mile Historic District, 29 West 21st Street is an intimate collection of just six full-floor loft residences, thoughtfully transformed with a design language that balances the building’s industrial heritage with Scandinavian simplicity and warmth.

Moments from Fifth Avenue, Madison Square Park, celebrated dining and shopping, and exceptional transportation, The Maisonette offers something increasingly difficult to find in Manhattan: the scale and soul of a classic downtown loft, the privacy of townhouse living, flexible living possibilities, and a hidden outdoor retreat—all in the heart of Flatiron.
