Thanks for that LINK johnny, I didn't know that the 'Grainger Town Project' still had its own Website.some shops probably use upper floors as storage space, especially where the ground floor floorplates are small. there is a lot of unlocked potential there though i do remember quite a few new flats being converted during the grainger town project- for instance the central exchange buildings.
according to the project's website over 500 new flats were created in the area - sure a few were new build though. some examples listed here - http://www.newcastle.gov.uk/grainger.nsf/a/property?opendocument
I have added that link to the Websites Thread, at "Section 16", I couldn't think of any other section to put it in, unless you think differently?
