Just to add that I have today been for a meeting with the Head of Inward Investment at DDC to look at the 'bigger picture' and how the Heights fit into it, as a representative of the Western Heights Preservation Society.

Hopefully the below map that I have been given the OK to circulate, as it is in the public domain, will help assist the discussion.
Here is a link to the full size image that will hopefully work:
