The duo's primary consideration during the design phase was to create a fully-functioning family home. "We are always thinking about our kids", Novogratz explains. "They needed a place to run around in the city, so putting the gym in was a pretty obvious solution. It may be out of the ordinary, but it is better than having your children skateboarding through the kitchen!" The couple's oldest son, Wolfgang, is a champion basketball player. While the court provides him with a place to hone his skills, it doubles as an entertaining space. "We knew we needed to use the space efficiently so it could work for everything", says the designer. From watching movies on a retractable screen, to hosting a 40-guest Thanksgiving dinner, the gym has proved itself as a good move. It has even been a haunted house! Adrienne DeRosa Photography
