The perfect marriage of sleek minimalism and functional modernism, this spectacular home is a one-of-kind masterpiece, designed by Mary and Joseph Merz, and recently renovated and expanded to perfection with the assistance of the original architects themselves. Spanning over 45' wide, this home offers the drama of an open and expansive living space, allowing you to live a contemporary loft-like life with all the homey benefits of townhouse living; including multiple outdoor spaces, total privacy, and your very own garage. Double height ceilings with radiant skylights; glass, steel and oak custom staircases; a glass penthouse with Japanese soaking tub; chef's kitchen with eight burner Blue Star Range and three ovens; and a dramatic rear curtain wall on the living spaces and bedrooms that brings light streaming into the house all day. The flexible layout includes 5 bedrooms, 5 baths, a 1500 sq. ft great room with slate wood burning fireplace as centerpiece; a library; a family room; and a large double height recreation room that functions equally as a play room, a media room, or both. Every room has been transformed with custom cherry millwork & closets, offering hidden storage at every turn. No luxury has been spared, including a 5 zone heating & cooling system, large wine cellar, Niles sound system, Japanese landscaping, glass & slate bathrooms, and a Zen-like master suite complete w private access to a penthouse w partial Manhattan views, media closet, and gas fireplace.
