Architects were faced by a task to make class A office in the former parking. Except working rooms here are provided: separate client zone, VIP-floor and dining room for employees. The main problems of the building were its deep and low ceilings. The client zone was situated in the lowest part of office because of features of functional zoning. We tried to preserve an illusion of big space as much as possible. In a ceiling zone engineers tried to avoid any crossings of the equipment. Only ventilation was placed there. Instead of bulky fancoils the technology of "a cold ceiling" (thickness is only 5 cm) was applied.
