Danish firm Een til Een just unveiled the world’s first “Biological House.” The designers developed a process that converts agricultural waste (including grass, straw and seaweed) into raw building materials – and the resulting home leaves virtually zero impact upon the environment.
Supported by the Danish Ministry of the Environment Fund for Ecological Construction, the architects built the eco-friendly home in secret for the new BIOTOPE ecopark in Middelfart, Denmark. The project – which was designed by advanced digital production technology – was first and foremost guided by sustainability at every stage.
The architects sourced various agricultural “leftovers” for the project’s building materials. Mounds of recovered grass, straw and seaweed – all of which would, under normal circumstances, be burned for energy – were processed into raw materials to be used in the home’s construction. Not only were the products upcycled, but the environmental impact of burning them was avoided.
The home’s sophisticated cladding was also chosen for its strong eco-friendly profile. Kebony modifies sustainably-sourced softwoods by heating the wood with a bio-based liquid, basically polymerising the wood’s cell wall. This innovative process, which was developed in Norway, coverts softwood pieces into durable hardwood panels, perfect for building. In the case of the Biological House, the silver-grey cladding will develop a patina over time, giving the home a beautiful rustic character.
The home’s construction process was also environmentally-forward. The architects tested and developed many innovative technologies during the construction process that would reduce the project’s impact. Instead of building on a typical concrete foundation, for example, the home was built on screw piles. This allows the home to be easily removed at any point, without causing damage to the terrain.
