I'm really interested in a collection of associated images from this blog link.
Seems to have been work produced by Sheffeld MA Architecture students back in 2009 as part of a project of some kind. I don't know more about it than that.
One diagram that I particularly liked is shown below.
If the original creators see this and want me to remove the image that's fine, but would be interested to know more about the project that led to the creation of these diagrams.
They would also be really useful, I think, for those starting to grapple with the Changing Place, Changing Places unit on the new 'A' level specifications.
