The Times Online (UK) covered a temporary home called The Universal World House by inventor Gerd Niemoeller.

It is made of paper, but according to The Times:

The interior of the prefabricated building panels resemble honeycombs; an air vacuum fills each of the units. The result: a strong and stable exterior wall, well insulated.

Wow:

Retailing for about $5,000 (£3,375), the house is supposed to brighten up Third World shantytowns and provide quick shelter for long-term refugees.

...the 36sq m paper house weighs barely 800kg (1,763lb) — lighter than a VW Golf.
