Renewbuilding designs, produces and assembles the biobased hulls. We call them Green Structures. Biobased vapour permeable construction is not yet standard. To make sure that the situation on site corresponds with the planned construction method, Renewbuilding assembles the circular hulls itself.

As soon as the ground floor has been laid, we come and assemble the shells. After assembly, the houses are wind and watertight. We then carry out a blower-door test and hand the certificate to the contractor. When the Act on Quality Assurance in Construction comes into force, there is sufficient proof that the house has been tested and meets the set requirements. We leave nothing to chance.


Renewbuilding believes that bio-based construction must also be efficient. This is the only way to make the building chain CO2-neutral and to make ecological living and working accessible to everyone. We see great opportunities in the use of natural materials. The growth of these materials requires CO2 and their use in construction ensures CO2 storage. We support efficient bio-based construction, without any loss of quality. With our prefabricated Green Structures, we go further than the Buildings Decree prescribes. We gain this back through efficiency on the building site and a sophisticated production process at our sustainable production sites.
