Open shelving can cut both ways: Curate the air out of all your cool stuff and you're left with a gift shop, not a home; but beware piling everything into an open space for fear of a visual muddle. The residents of NHR strike a great balance of colorful activity without getting too precious. Neutral flooring, a dark wall help, and a blue Unfold pendant lamp from Muuto keep a sense of play without tipping into formless clutter.
