For the recently renovated Biesbosch Museum in the Netherlands, it's a return to nature. The site was turned into a manmade island and both the existing and new wings were covered in a green roof that turns the galleries into grassy pyramids.
Located near Dordrecht, the permanent exhibits explain the historical development of the region, while the new wing new wing houses a restaurant and temporary exhibition space for contemporary art.
The surrounding site was also transformed into a manmade island, part of a national safety project as a water retention site. Set to be completed in the spring of 2016, the site will include a freshwater tidal park that receives river water through a newly dug creek.
