In the future, will all houses come ready to assemble?

Prefabricated housing couldn't be more eco-fashionable, and it's not hard to see why. Whether temporary or permanent, a flat-pack house can go pretty much anywhere (as long as you have water & electricity supplies - and permission!). And it's increasingly affordable: the cheapest option on the market is a mere $12,000. Music to the ears of the adventurous first-time buyer.

But we're talking about an often radically different style of home. So we ask - would you feel comfortable in any of these five houses?

The Orb (above) - read the full specs at If It's Hip, It's Here, or on the official website here.

Again with the shipping containers - this time it's the turn of Port-a-Bach (above), from Atelier Workshop Products.

Coming in a variety of sizes - and somehow packing in two floors  - is the Eco Pod (above), from Eco Hab UK.

More your thing? The Method Cabin (above) - spotted via Haute*Nature. Much more conventional-looking, this home is factory-built before taking about 3 months to be assembled onsite.

No glue?  No nails? It's Lego for adults - the Loq-Kit home (above), made from modules that snap together any which way you like.

Or how about any of the 7 eco-houses we recently featured?
