It’s build-your-own-dream-home time! Here’s a look at a completely gutted brownstone triplex right off Central Park. This 2,100-square-foot pad provides the perfect excuse to grab your interior designer and unleash your imagination. The space includes the parlor, garden level, and basement of a prewar co-op, with a 750-square-foot backyard. And it can be yours for $2.495 million.
