The design concept was to create various wooden boxes that intrude into the original brick facade, in order to break the narrow monotony of the building and provide wider spaces for the users. These boxes have different sizes and heights to accommodate a variety of functions, each with a glass wall facing south to allow maximum daylight. A new elevator tower connecting all the floors was created in order to establish universal accessibility. The tower cladded with brick, identical to the original building, establishes a new landmark, with a trademark railway clock on top.
