Offering a piece of serenity and privacy is priceless among the hustle of the Big Apple, and that’s certainly part of the appeal of Manhattan House’s lobby. It overlooks the building’s one-acre private garden, redesigned by Sasaki Associates with new plantings and walking paths. Two sculptures by Dutch artist Hans Van de Bovenkamp offer points to reflect and relax. A three-bedroom, three-bath condo is available in the building now for $5.495 million through Warburg Realty. The 2,588-square-foot unit includes two private balconies and access to a range of amenities, from a spa and yoga studio to a rooftop lounge.
