357 West 17th St.

Inside this Chelsea townhouse that defies all comparison, there is no single design element that isn’t “wow.” From its double Saint Laurent marble kitchen islands to a magnificent two-storey constellation chandelier, the five-story Midtown wonder is designed to astonish with its luxury and scale.

Its massive marble mantle, wine cellar, private movie theater, resistance pool, gym, yoga room and sauna are all custom, in line with the one-of-a-kind nature of the property itself. Large open spaces with soaring ceilings retain a warm feel through cozy furniture and soft accents. A 2,000-sq.-ft. rooftop terrace is one of several outdoor spaces that are as beautiful, comfortable and well-equipped as indoors.

The attention to detail is phenomenal, with even a powder room sink feature that resembles a modern sculpture. Gorgeous art, extensive marble and magnificent mosaics contribute to the elegance of this extraordinary home.
