The assumption behind the design is the performance of an architectural or urban planning task of medium complexity (e.g. a public building design with a floor area of approximately 5,000 m2) during which advanced visualisation of selected solutions in a virtual reality environment is applied.

In the initial design phase, following the definition of fundamental qualities of the structure, participants isolate parts (physical or ideas) of the concept that shall be developed in the virtual layer. The virtual space may be provided with functionality in selected situations, which underscores the interactive character of the concept.
