Paper House

Swiss company, The Wall AG, has designed the "Universal World House". It is a $5,000, 390-square-foot modular home, complete with plumbing, sleeping facilities to support up to 8 residents, and a convertible closed/open-air kitchen with table and benches.

The secret of its construction is its "paper" shell; the resin-soaked cellulose, made from recycled paper, is shaped into honeycomb walls, which provide structural integrity and insulation to the houses. Countries that have placed orders for the UWH, include Nigeria and Angola.
