The station building, which was internally modernised and externally restored in 2007, houses several dining establishments, lockers for luggage and a Deutsche Bahn travel centre.

In October 2006, the renovation of the building began with funding from the urban development subsidies of the government of North Rhine-Westphalia.

The main reasons for the renovation were significant deficiencies in its equipment as well as a lack of access for the disabled.

The station’s prince's room (Fürstenzimmer, built for royalty during the German Empire) was listed as the monument of the month in Westphalia-Lippe in February 2008.
