Truly extraordinary 3,309 square foot, 4-bedroom, 4.5-bath corner residence with a sprawling open floor plan and breathtaking Madison Square Park and city views at coveted 10 Madison Square West. Expertly conceived by world renowned designer Alan Wanzenberg, this impeccably crafted residence offers supreme comfort and luxurious livability. A beautiful hardwood entry door with custom Nanz hardware is the stunning prelude to the harmonious experience beyond, where wide-plank white oak floors and beamed approximately 10'7 ceilings add rich character to each well-balanced room. Beyond the gracious entry Foyer, an enormous central Gallery anchors the residence and conveys a true sense of grandeur, separating the private master suite, the public spaces, and the bedroom wing. A second gallery adjoins, traversing the residence and leading to the massive 22'9 x 37'2 corner Great Room, featuring three soaring windows that offer stunning views of iconic Madison Square Park and the sweeping cityscape. Ideally suited for grand-scale entertaining and sophisticated daily living, the unique space flows seamlessly into the sprawling open chef's Kitchen, which features a windowed dining area and additional breakfast bar. Elegantly appointed with classic white SieMatic cabinetry and Bianco Carrera marble, the Kitchen also includes top-of-the-line appliances by Sub-Zero, Wolf, and Miele and a separate back entrance leading to the home's central Gallery. The private Master Suite is an absolute oasis, comprising a sumptuous 18'8 x 13'2 Master Bedroom with two enormous east-facing exposures that look out over Madison Square Park, three walk-in closets, and a lavish Master Bath featuring a custom double vanity, soaking tub, and separate stall shower. Three generously proportioned additional bedrooms each feature large south-facing exposures and en suite baths; the fourth also includes a walk-in closet. A beautiful Powder Room and Utility Closet with side-by-side washer and vented dryer complete this exceptional residence.
