Earlier in the year, a unique house designed by the Danish architects Een Til Eeen, which was supported by the Environment Ministry, opened at the new Biotope eco-park in Middelfart. ‘The biological house’ is novel in that it has been constructed exclusively from agricultural waste products that otherwise would have been burnt – with the resultant environmental pollution – such as grass, straw and seaweed. The house, therefore, leaves almost no impact on the environment, reports World Architecture News.com. The cladding used on the outside of the house has been developed in Norway. Called Kebony, it is made of sustainably-sourced softwoods that have been heated with a bio-based liquid that polymerises the wood’s cell walls, giving it high durability, hardness and dimensional stability.
