Lathe walls enclose the sleeping area in a 400-square-foot Brooklyn apartment. "Inside, it's hung with white curtains," Lyndsay Caleo of The Brooklyn Home Company says. "It's incredibly cozy, like you're in a nest, a cocoon, but it's still light and airy." The Brimnes bed from Ikea has drawers underneath, for more storage. "We decided to define a sleeping area, because we felt people needed a private space," says design partner Fitzhugh Karol.
