A typical New York winter wouldn’t normally include the kind of Monday the city experienced this week, sunny and touching 60 on the thermometer. Global warming fears aside, it makes us think about those apartments in the city that have access to beautiful outdoor spaces built for lounging with family and friends. CORE’s jaw-dropping Chelsea penthouse at 166 West 18th Street, also known as Yves, is so massive and modern that some of the little things — like this private 230-square-foot terrace — tend to go unnoticed. But the way it’s been decked out makes it ideal for capturing those fleeting moments when the New York winter is wonderful.
