The feasibility study intends to highlight both opportunities for new business for tourism, landowners and the Wood Industry, as well as providing documentation for relevant actors in several industries to enter an implementation project. This through the use of land in a new way. Instead of permanent building permits, sustainable and environmentally/energyally optimal living methods are applied for 5-15 years to be phased out (reused in a new location) without leaving traces in nature behind. This specifically involves applying circular systems for land development for 5-15 years to create new business. The sharing economy and the circular economy (revolving 15-year life cycle) can be of great importance for the creation of new business models when applied in land development. The implementation of the feasibility study is done through: 1. Analysis&Conclusions related to real estate law and the legal spaces that enable and limit in PBL or. The Environmental Code. 2. The preliminary study intends to produce documentation/assembly for which technical solutions sustainable VA solutions can in the future create circular use of land and buildings without leaving the interventions that traditional exploitation involves. 3. The feasibility study intends to spread knowledge to actors and industries to establish new circular business models linked to the feasibility study reports. And lay the foundations for an implementation project with anchoring in several industries (building, soil/forest, tourism industry). At the centre of the feasibility study is thus new working methods around circular land use via temporary building permits for 5-15 years and new business and business models around this.
