I came across this interesting design for a hotel/resort complex on (or is that 'in') the site of an old quarry. This huge pit complete with water in the bottom is a fascinating site to begin with and the architects, Atkins, have created something that works up the side of the rockface incorporating underwater levels, glass waterfalls, water filled walls and more.
I am not sure if it is actually under construction (or even going to be) - but it would be great if it were. The images below are obviously CG, but are quite evocative of the place. I think this would make a great environment for a real-time rendition.
