The study will give an opportunity to solve some problems of already modified environments or landscape continuous degradation by developing rehabilitation projects, providing new interesting solutions related to the aesthetic and technological aspects, as well as the materials that are being used.
Forasmuch as a significant part of monuments has already lost its initial areas in urban structure which is getting denser and denser every day, in such a case, it is much easier to return its dominance status, emphasize its identity, and the image related to new neighboring structures using contrast effects for the latter's (material, volume, decoration, scale, exc.).
And for the existing inappropriate architectural solutions "rehabilitate" the worthless structures using different materials and investing greening vertical systems.
