Here’s a visually interesting West Village duplex that has an open floor plan, exposed brick, and high ceilings. But the pièce-de-résistance is a spiral staircase leading up to the master bedroom and private roof deck with views of the Empire State Building. Pets are allowed and there’s laundry in the building.

This bright 2-bedroom, 2-bath penthouse offers plenty of room to roam, including two separate private outdoor spaces and a study. There’s a small balcony off the living room, but the big jewel is a 550-square-foot roof deck on the second floor. The incredibly low monthlies ($712) will make you do a double take if the outdoor space hasn’t done so already. A deeded parking space can be purchased separately.
