The story of modern prefab housing is one of unfulfilled potential. Magazines like Dwell will the industry forward, but the houses remain as expensive as conventional homes. And they're rarely actually manufactured, merely built indoors. So it was hoped that MoMA's Home Delivery show, which includes five prefabs assembled a side lot, might be a watershed. Alas, the models shown are innovative, but all quite unlivable, ranging from po-mo prison cells to the unique but sterile KieranTimberlake structure shown here. We've still got a long ways to go before modern homes can be ordered up and delivered affordably.
