The exposed brick walls in this apartment were a huge selling point — and they work beautifully with Singleton's amazing art collection. Here, Singleton put three pieces on the main living room wall: "Baby Deer" by Sharon Montrose (bottom right), "Stacked Upon" by Jaclyn Mednicov (left), and "Pores" by Anastasia Ugorskaya (right). A perfectly suited splurge — the Chi Chi Kari rug by Madeline Weinrib — sits on the living room floor.
