A new, modern building for the German Wallpaper Museum is currently being built at Brüder-Grimm-Platz in Kassel. Large parts of the collection are expected to be exhibited here from 2026 on around 1,500 square meters.^{I'm sorry, but I need more context or information to provide a translation. Could you please provide the text you would like me to translate into English?} An exhibition space will also be shown. A large storage facility with a restoration workshop for the wallpapers is also planned. The foundation stone was laid on June 30, 2023 - exactly 100 years after the first opening of the wallpaper museum.

The new museum occupies a central location in the city center of Kassel, which also has a special significance for the history of spatial art: Between 1815 and 1883, one of the first German wallpaper factories was located here. The building of the adjacent historical "northern gatehouse" will also be integrated into the new construction in the future. The Brothers Grimm lived here from 1814 to 1822, and their work at this location is to be commemorated in a museum setting.

The future visitors to the new museum will embark on a chronological tour through 600 years of wallpaper history. The wallpapers are presented in 21 cabinets as real room settings, along with contemporary furniture, decorative arts, and historical clothing. There are a total of six thematic sections: gold leather wallpapers, variety of materials, early days of paper wallpaper, panoramic wallpapers, wallpapers at the World Expositions from 1851 to 1900, and modern wallpapers from 1900 to the 21st century.
