The only maisonette at 150 Charles Street with a private internal elevator, M10 makes its first-ever appearance on the market as one of the most significant residences within the building. Expertly redesigned by designer Sane Designs, this extraordinary townhouse seamlessly blends the privacy and scale of single-family living with the services and prestige of West Village luxury condominium living. Every inch of the home has been meticulously curated with bespoke finishes, custom architectural detailing, and a level of craftsmanship rarely seen in downtown Manhattan. A private entry welcomes you into a richly layered interior defined by custom stained white oak millwork, steel detailing, and bespoke architectural moments throughout. The dramatic great room and formal living spaces are illuminated by sculptural Apparatus fixtures, while custom-designed lighting, Phillip Jeffries wall coverings, and handcrafted steel and glass elements create a residence that feels both deeply luxurious and remarkably intimate. A custom steel fireplace anchors the living room, bringing warmth and artistry to the entertaining spaces. Designed for both entertaining and everyday living, the home features a fully integrated in-wall Sonos sound system throughout. The custom Molteni kitchen is equally refined and functional, appointed with Alabama white marble countertops, Lefroy Brooks fixtures, and a full suite of Miele, Sub-Zero, and Wolf appliances. The kitchen opens beautifully into the surrounding front living and dining spaces. The primary suite is a true private retreat, wrapped in Phillip Jeffries wall coverings and complemented by bespoke McEwan lighting and custom Poliform closets. Every room throughout the home reflects an uncompromising attention to detail, from the Matthew Fairbanks sconces in the primary bath and entry vestibule to the curated custom lighting installations extending into the landscaped outdoor space. Designed by the renowned COOKFOX Architects with interiors by Alan Wanzenberg, 150 Charles has long represented the pinnacle of full-service West Village living. Residents enjoy over 40,000 square feet of private landscaped green space, a covered private driveway and parking, white-glove concierge services, and an unrivaled wellness experience including a 75-foot pool, spa facilities, fitness center, yoga studio, steam room, sauna, plunge pool, massage rooms, and private entertaining spaces. Maisonette M10 is more than a residence. It is a rare opportunity to acquire a designer townhouse within one of downtown’s most architecturally significant condominium buildings, combining the privacy and scale of a standalone home with the services and amenities of a world-class luxury property.
