The New Museum with a Glass Roof

The Biesbosch Museum in Netherlands recently reopened its door. The Museum is the starting point for Beisbosch National Park, and the old building did not have the capacity to host the growing numbers of visitors.The extension of the original building that houses an organic restaurant and a temporary exhibition space for contemporary art was designed by Studio Marco Vermeulen. The hexagonal structure of the original building was retained to minimize the waste while the permanent exhibition area that explains the historical development of the region has been redesigned by Studio Joyce Langezaal. As a part of a national safety program, the land around the museum was removed and turned into a man-made island with the area converted into a water-retention zone. Museum buildings are surrounded by earthworks and covered with a roof of grass adding ecological value to the area and blending into the landscape.
