"I think that small spaces inherently demand inventiveness," architect Michael Chen says. So when a client presented him with a brief to create a multi-functional element that was kitted out with refrigeration, storage, a beer tap, a humidor, and a dining area, Chen created what he calls a magic box. It boasts an army of features, but discreetly hides them all when not in use. "Sometimes we call them architectural appliances or transformers because that’s what they do," Chen says. "Conceptually they are appliances; experientially we like to think of them as magic boxes because they’re fun in that way."
