During July 2009, it was announced that the Polish government had signed a construction agreement with the Spanish construction firm Neinver, under which the latter would perform the construction of a new integrated transportation hub and commercial center in the middle of Katowice. This programme involved the reconstruction of the existing railway station, along with the construction of an underground bus station, an adjacent shopping center ("Galeria Katowicka") and an office tower; other changes included the reconfiguring of various streets, sidewalks and public space located around the railway station. 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.
