I hope any new planning policy will place an increased emphasis on sustainable development that encourages the reuse and repurposing of the existing built fabric rather than demolition as a means of clearing the way for such new high rise developments.

Oh! You gotta larf. Strategy? How high do you want to go? That high? Fine. We'll just put your investment proposal through the rigmarole of 'a wholly transparent pseudo-democratic form of accountability' to and by a 'planning' system that is never going to refuse any multi-million pound development in its city centre irrespective of the city's victorian heritage. We can and will justify anything. After all, 'it's the economy, stupid'
Now the grid iron's just the wild west chicago style. Roll up! Roll up! Be assured, we are not like those *****rs in Edinburgh, over here we're open for any and all kinds of business.
Ther, that's your Glasgow city centre planning policy, save you the bother.

Whisper it........but number 2 has most certainly never attempted to get a development through the planning process. He has also ignored the political context of the current administration and their ongoing battle to ensure the city centre economy is trashed bit by bit.

I much prefer this alternative system alluded to by number 2. If he/she/they/them ever fancy replacing the right dishonorable Susan them I'm fully behind this refreshing 'can do' approach.

It's a bit late for embarking on this strategy given the number of panning applications already submitted for very tall buildings.
What I think is more more pertinent is not tall buildings per se but where they are located.
For example I think it is entirely appropriate for vey tall buildings to be sited in the Charing Cross district of the city but not in other more central locations.

What is the lifespan of these buildings?
What happens when the educational establishments do not offer what the students want?
What happens if Glasgow falls out fashion for tourists?
How easy will it be , when we are not here anymore , to demolish and start anew?

Hope this means Stallan Brands weird but cool St Enochs tower might get built

Number 3 - It beats me why would you presume to know anything about an anonymous contributor to a comments section on Urban Realm.
From memory I can think of ten city centre developments over the course of my life, that I have been involved with in negotiating with planners, not all in Glasgow.
The political context of the current local administration is really neither here or there. It is the wider political context and especially in post-Brexit UK that is the story i.e. the movement of capital which ultimately affects the globalisation of the City of Glasgow . By the way, the SNP have been toast politically since 2014. They are an irrelevance.
But my point is really that planning ‘policy’ in my experience regarding buildings is not worth the paper it is printed on. It is a political charade. The reality is it is individuals and individuals in positions of power and monied vested interests that shape our built environment, not planning ‘policy’. Call me cynical by all means, but that would be my lived experience. And of course, what this invested capital all looks like is a banal and truly heartless amalgamation of industrialised components and not architecture, because every last ounce of profit for these movers and shakers is God.
This is what people complain about when they look up at their surroundings.
