The office design philosophy is based on the system’s design approach, integrated design approach and design of transformable structures approach. System’s design approach One can make distinction between traditional design approach where architect defines building typology for specific program, installation advisors add heating, cooling and ventilation elements to it and structural engineer insures its stability. Opposite to this we believe that architectural, structural and installation components should all be a part of one integrated design concept where, all subsystems of the building form the total building system. One can name such approach architectural engineering.
