The paper is dealing with the conservation of the traditional construction heritage through its obtaining a new function (e.g. tourism), for which a radical reconstruction of the objects by means of new materials and new technology is necessary. Through a series of examples from practice it will be shown how the original appearance of buildings and gardens can be conserved, paying thereby attention to the authentic construction elements and avoiding erroneous solutions when conserving and restoring the existing architecture in rural areas and, at the same time, combining new and traditional materials, raising the level of accommodation comfort and the energy efficiency of the objects. The heritage is a testimony of survival of a people in time and space, an expression of homeland identity and cultural sovereignty. By sensible restoration of desolate objects of traditional heritage and by using new energy efficient materials, their originality would be conserved and a new impetus to their conservation within sustainable regional development would be given.
