I agree that the loss of the St Enochs hotel, countless churches, tenements etc etc have been absolutely cataclysmic for Glasgow. But whats done is done, don't you think its time to move on?
As for the quality of the new architecture, I believe it stands up well. Glasgow is fortunate to have a wealth of home grown architectural talent, Cooper Cromar, Murray and Dunlop, Page and Park etc, all are producing fine buildings.
Not all of it is great by any means though, the new Jury's Inn is horrid as is the Buchanan Galleries car park, but you shouldn't tar all new buildings with the same brush. The new Radisson SAS on Argyle street is an absolutely superb building and more is yet to come, Elphinstone place, Aurora, Sentinel etc all promise to be spectacular.
Take a walk along the Broomielaw and tell me things haven't improved.
The Pinnacle and Eagle House's contribution to the streetscape.
And another thing, all these projects are either replacing Sixties/seventies disasters or are going up on brownfield sites, something we should all be encouraging.
The Victorian stuff will remain untouched.
