Shimao Wonderland Intercontinental is a design for a hotel in Songjiang in China. It is aimed to be a 5 star resort built into an old quarry. It makes use of all three elements which the brief for this project describes, albeit in a slightly different way. It is built up by approximately 90m, and yet is also underground.
I love this design, I think it is an inspiring use of an existing site which could be otherwise considered a problem. Furthermore, I feel that this is a much better way to build such a large building. It makes the hotel blend away into the landscape and does not disrupt the landscape. This is something which I would love to incorporate into my own designs.
