The station's building was created between 1925 and 1928. It has been functioning properly until today, but it was very neglected.
The modernized object is situated at the corner of Kolejowa, Opałki, and Składowa Street in Koło. The main building is placed parallel to the rail line, and there is a parking lot on the side of the street. It consists of two high side wings and a lower middle part, holding the main entrance to the customer service area. The surroundings of the building were devastated, lacking small architecture and functionally ordered spaces.
The concept of the Koło train station development includes improving its central space: increasing the lounge area, organizing places to sit, setting up public toilets. The lounge includes the entrance to the library and the reading room. The library exits to the platforms. Part A of the building holds a storage room for the library. There are also separate spaces for an internet room, toilets, and a TV room in part A. the second floor has a social room for the library staff, an instructors' room, and compilations of the library collections.
The concept of wing B involves introducing rooms designed for the needs of the hotel situated on the first floor. Here we also find social rooms for the hotel staff and the manager's office. The ground floor of this part of the building holds the reception, along with a toilet. This wing of the building also includes a security room and an exhibition hall, adherent to the library. On the top floor of part B there are the library manager's offices and the accountant's office with a bathroom.
