Architectural activity processes have been studied. In architectural practice, the place of the architect in the process of developing an architectural object has been reconsidered. The architect is looked at as an artist and space developer. The engineering and strategic part of the architectural project is now dealt with by other professionals. In architectural science, the basic principles of architectural theory are reviewed to fit the needs of today. There are indications of transition from the material or the abstract material to the phenomenological, sensual, transcendental. The attitude towards the environment is changing qualitatively: augmented reality allows both the old and the new to “exist” in the same territory (with the help of special tools). The attitude towards heritate conservation is also changing dramatically. The study of actual architectal activities in architectural practice and scientific activity has revealed a range of problems that are currently being addressed: development of new teaching aids for architectural education, and development of materials for practical use in building design and urban planning.
