A refurbishment with curved protections 
This case is actually about a great example of cosmetic wrapping of an old industrial building, to get a contemporary and unified image.
A highly perforated metal sheet forms a kind of curved curtain, covering almost the entire building.
It hides opaque walls, but also protects the openings. As to what these images show, the wrapping reduces the size of the windows and, as it is separated from the façade, forms a kind of curtain that protects the glare when the sun is high.
