A rare full-floor maisonette at the intersection of SoHo's industrial heritage and contemporary design, Residence M3 at 30 Crosby Street offers an extraordinary scale and level of privacy seldom found in downtown Manhattan. Spanning multiple levels, this loft-like home unfolds through a dramatic sequence of entertaining spaces, private retreats, and wellness-driven amenities, all tied together by soaring proportions, warm materiality, and architectural detailing throughout. The main living level is anchored by an expansive great room with exceptional ceiling heights, oversized steel-framed windows, and a striking palette of exposed timber beams, cast-iron columns, and wide-plank hardwood floors. Triple-paned windows and a private entry foyer creating create exceptional sense of separation from the outside world, offering a level of tranquility rarely associated with downtown living. The scale is remarkable yet intimate - equally suited for large-scale entertaining or quiet daily living. A sculptural open kitchen is positioned just beyond, designed with oversized marble surfaces and extensive custom cabinetry. Adjacent dining and gathering spaces continue the home's seamless flow, creating a layout that feels more akin to a private townhouse than a traditional condominium residence. The bedroom suites are privately situated and thoughtfully designed, each incorporating a distinct material language of exposed brick, custom woodwork, steel, and translucent architectural panels. The primary suite is particularly impressive, offering a dramatic loft aesthetic softened by warm woods and tailored detailing, along with a spa-like bath finished in crisp stone, polished fixtures, dual vanities, soaking tub, and separate shower. A floating architectural staircase connects the home's multiple levels, leading to additional lounge, fitness, and recreation areas that further distinguish the residence from anything else currently available downtown. Wellness amenities include a dedicated gym area, sauna, and flexible secondary rooms ideal for media, office, studio, or guest use. Completing the home is a beautifully designed private outdoor terrace - a secluded extension of the interior living spaces and a rare luxury in the heart of SoHo. 30 Crosby Street is an intimate and discreet boutique condominium perfectly positioned on one of the neighborhood's most coveted cobblestone blocks, moments from the finest restaurants, galleries, shopping, and cultural destinations downtown. Residence M3 represents a singular opportunity to own an architecturally significant maisonette with true scale, privacy, and character in the center of SoHo.
