The first thing I thought when I saw these Cabanne modular spaces was that they looked an awful lot like those cheap portable carports with a rainscreen put on them. I say that as a good thing though, because I love the idea of an inexpensive and attractive semi-portable source of shade. The Cabanne was designed by architectural firm Bestetti Associati in collaboration with furniture manufacture Paola Lenit, and is a "modular system, allowing for endless possible architectural solutions tailored to the spaces, the situations, the requirements”.
Made of steel and iroko wood (similar to a teak) the structure is probably neither affordable or portable, but what if you were to add a rainscreen to affordable steel carport? It could be a nice little outdoor space for not a lot of work or money.
