Surrounded by a 1,344-square-foot network of lushly landscaped terraces–including a rooftop with a hot tub, outdoor kitchen, shower, and pergola–this duplex penthouse at 15 Renwick Street in Hudson Square feels like a garden in the sky. Asking $8,975,000, the 2,859-square-foot duplex has floor-to-ceiling windows and a windowed kitchen to gaze at the greenery.
