In addition to these advantages, the profitability of construction of such houses is caused by the use of local materials. Now, not every town can boast the presence of cement, aluminum and other factories, processing raw materials extracted in the same area. And the use in the construction of this almost universally-common raw materials such as straw, can significantly save on shipping.

in the country should be constructed in 10 eco-towns. The Swedish government decided to reconstruct the ancient city of Malmo (Malmo), which is home to about 280-thousand people.
