One-of-a-kind, SoHo architectural masterpiece, encompassing over 8,000 square feet of interior and 4,000 square feet of private exteriors. This private, bespoke residence at 421 Broome, a small boutique landmarked cast-iron condominium dating back to 1873, provides the owner the comfort of full-time doorman services as well as title to an exclusive rear yard with two parking spaces. Designed by AML Architecture/Roman and Williams, the home recently underwent a complete transformation with entirely custom fabricated steel doors, windows and skylights and unrivaled attention to detail. With direct elevator access to each of the living areas leading to entries appointed with profiled custom steel gates, this Penthouse property begins on the 5th Floor, opening into an extra-wide entrance gallery leading to the grand great room. Marked by six oversized arched windows, this room overlooks historic Soho below 15 foot ceilings and two skylights, anchored by two massive wood-burning fireplaces. Outfitted to the liking of a professional chef, the spectacular 20-foot brick barrel-vaulted ceiling kitchen includes an 86-inch range, granite countertop/backsplash and wood-burning fireplace, as well as two proper butler's pantries and wine rooms. A second master suite with a private terrace, two additional bedrooms with bath, and a laundry room complete the floor. Encased in a LaForge bronze stair railing, a Chesney cantilevered black marble staircase leads to a master level with his and hers bathrooms. This master suite, perhaps the most beautiful in the city, complete with walk-in dressing rooms, coffee bar with refrigerator, wood-burning fireplace and dual private terraces, is unlike any other. The top level opens to entertaining terraces, paved in Cenia Gray granite, designed for indoor/outdoor living with large heated, hotel-style, steel and glass canopy, wood-burning fireplace, and TV alcove, all accessible by six sets of French doors.A screening room with wood-burning fireplace, fitness room, second full kitchen and laundry, and dining room have been intelligently placed to serve this floor's interior. Three additional landscaped terraces, equipped with custom gas lanterns, offer a heated spa, fountained garden, and open-air dining. An adjoining staff room with full bath and over 700 square feet of built-out, cedar and marble, storage rooms completes this incomparable residence.
