 Inside the building, communication between floors was ensured with the construction of 6 main escalators and 4 elevators within a central stairwell, these were further supplemented by a multitude of other minor escalators and stairways; this made CDT the second building in Warsaw to use moving-stairway technology.The building has two major emergency exits which lead directly down to Bracka and Krucza streets.The lobby of the store was originally decorated with terracotta wall tiling and oak flooring whilst the basement floor utilised reinforced concrete with glass and steel fittings; the use of these materials was then expanded to outfit the whole store.
