Around 1900 the premises of both libraries were getting too small. The situation eased when the local businessman and patron Fredric von Rettig donated a new library building for the city. In addition to the building, von Rettig also donated 10 000 books, an art collection and a considerable sum of money for the maintenance of the libraries. The architect of the new library building was Fredric von Rettig's own son-in-law Karl August Wrede. The building was designed in the style of Dutch late Renaissance, and the immediate model for it was the House of Nobility in Stockholm. The People's Library moved to the new building's ground floor, whereas the City Library moved to the first floor. The entrance to the City Library was from the main door, but the entrance to the People's Library was from a side door by Linnankatu. The People's Library and the City Library, both already located in the same building, were formally merged in 1912.

Very soon these new ideas and notions were put into practice in Turku. Most of the modifications and reforms were ready by 1914. The Turku City Library implemented open collections, free loans for everyone, long opening hours, a children's department and a modern classification system. The separate men's and women's reading rooms on the ground floor were combined, and newspapers were attached to racks from which the patrons could read them while standing. The side door by Linnankatu was also closed permanently, after which every one entered the library from the main door. The rules of use were revised so that loaning became entirely free and every resident had the right to loan books. This meant that the library was developing even more clearly towards a universal public library, because the number of patrons and loans increased signicifantly. However, The First World War and the Finnish Civil
