The American dream of owning a house can be so expensive that it remains, for many, just a dream. But two new forms of alternative housing offer solutions to those looking for cheap shelter—or any shelter at all.

Claiming a permanent seat on the prefab bandwagon, the home-furnishings store IKEA has created affordable, space-saving houses and apartments. The wooden residences boast multiuse rooms with generously sized windows and high ceilings. The project, called BoKlok, just arrived in the U.K. after a successful Scandinavian test run—and availability in America isn’t far behind. The new British homes, made available by Live Smart at Home, start at $160,000 for a one-bedroom flat. Now it’s just a matter of trust: Can you buy a house from the people who made the wobbly dresser that fell apart in your dorm room?

Some people—namely the homeless—have more pressing concerns than buying a house. But if the New York-based Chilean artist Carolina Pino has her way, they will soon be able to take their shelter with them. Pino’s Shellhouse concept is a collapsible, triangular, origami-inspired refuge made of cardboard—durable enough to provide a roof over someone’s head and light enough that it can be carried under an arm—with instructions for building a $30 radio transmitter, so transient people can communicate and update others on their locations.
