What's all the stuff in the middle of the roundabout, as a matter of interest? I assume at least some of it has a function of some kind. Is that what the collection of pillboxes in the left hand corner is for in the proposal?
No, the 'pillboxes' are only there to illustrate possible uses for that space. It's very unlikely that the functions which currently exist in the centre of the junction couldn't be accommodated in some other way. After all, you'd be talking about a whole new build on two or three corners.
