Architecture “after guarantee” which already exists sometimes needs only a few to be secondarily used. Community of people who can see a hidden potential in abandoned buildings is growing and they putt pressure on recovery and recycling because nature and its exhaustible sources are to demonstrate that the debt produced by our contemporary lifestyle have to be paid. These efforts are difficult on the level of communication between representatives of several factions participating in the conversion (or reuse-process). But if the community is so advanced that it is able to overcome the problems associated with the human factor, the architect himself have to take responsibility for creating high-quality conversion project.
In this phase the approach to revitalization is based on the degree of intervention by relevant instruments and the architect becomes not only a kind of “interior soul designer of the object, but also the exterior body designer”. “Conversion is generally more difficult than designing of new objects, because it is too modified by existing structures.” (Renzo Piano, 2008) In case of reuse design, it is especially detail that attracts attention due to various parameters which must pass through transformation. It is necessary to analyze, specify positive and negative properties of the elements, evaluate and then demonstrate the ideal methods of approach.
