The underground part of the complex will feature new multi-storey car parking facilities. Reportedly, the overall investment was estimated in 2009 to come to around 240 million euros. As planned, the redeveloped railway station is not to be entirely newly built; instead, it is intended to retain several existing elements of the building, albeit renovated and modernised where deemed to be suitable or necessary. The problematic cup-shaped pillars are one such element, being reinforced rather than removed; a grand new entrance into the main hall of the station is to be developed between the two cups. A glazed structure which connects between the railway station and the new retail and office facilities shall be constructed; the shopping and office complex are to be located upon a newly built elevation, composed primarily of perforated steel structures, these are reportedly intended to provide an aesthetically-pleasing lighting effect via their highly reflective characteristics. will make the building resemble a lighted city centre at night.
