Haus der Bayerischen Geschichte

GermanyGermanyCompany Name: A.S.T. Sommer GmbH

Project description

Regensburg’s new museum called “Haus der Bayerischen Geschichte” with 2,500 sqm exhibition space opened 2019 and its purpose is to show the recent Bavarian history of Bavaria with multimedia and experience-oriented exhibits. The challenges for the contractor were manifold such as the construction of shaft walls with a height of up to 17 meters and their perfect surface finishing in Q4. One of the architectural highlights is the free-standing drywall developed by the technical department of A.S.T. Sommer. This wall has a vertically inclined surface on one side and is designed to carry the historical Landtag carpet with a weight of 600kg. Furthermore numerous design elements such as integrated staircases with indirect lighting make an important contribution to the harmonious overall impression. The contractor’s extraordinary technical expertise was mandatory to create this outstanding new museum.


A.S.T. Sommer GmbH

Mr. Heinrich Sommer founded his company A.S.T. Sommer GmbH in 1989. He started with two workmen and today the family owned company has grown to a size of 50-100 employees. In those 30 years not only the company building was enlarged by the extension of the company premises, but also the technical product portfolio was supplemented by “room equipment” and “darkening”. Heinrich Sommer will shortly resign and the company will be managed by his son and successor Christian Sommer.
