Nature colonizes everything. Abandoned library with tree. I would love to have a thing of nature in a library it just seem so cool. I mean you can read your book on the tree! Even though it's abandoned that would be awesome.
Spiral staircase at La Conciergerie, Paris. Former royal palace and prison in on the Île de la Cité, it is part of the larger complex known as the Palais de Justice. Built in the Middle Ages as a Merovingian Palace.
Creative ideas for using the space under the stairs. Brilliant use of space! Not nuts about the bathroom idea though. I guess if you had a tiny home with no main floor powder room it could be workable.
