Couldn't agree more. The CBD is slowly growing southward, so it makes sense to create a southerly counterpoint to the likes of Elder Park and the rest up there. I don't believe anymore that Vic Sq will ever be "the place to be" in Adelaide, but putting it at least on the list of places to be would be a major leap for it. It is difficult to impossible to get a city to entirely refocus itself on a different geographical location; that's a cultural thing. At least when Vic Sq becomes a decent place to be, it will get a chance to develop its own culture and go from there.This may not be "the place to be"by the time Adelaide's makeover is complete, but it will certainly be on the list of places to be, and that's important. Adelaide doesnt want to be a one dimentional city with one central location, in fact its precisely the sort of city that it is currently trying to move away from!
I've said many times here before that no one REALLY knows what the square is actually for, as it is not and has never been the central civic space. This is one of the reasons that I like this design. It acknowledges an ambiguity in the space's function, which I suspect could be the key to it's success ultimately. I think it's as good as it's gonna get for the present. Plus I think the design allows for a possible future closing of the east-west road. That would be reasonably easy to do here and would create a third space that could be explored in a design sense. Flexible, practical and aesthetically pleasing. Good outcome.
The problem with Light's or Kingston's (or whoever the fuck's plan it was) is that it was conceived on way too large a scale. The South Adelaide grid is surprisingly huge overlaid on the comparable areas in the other capitals (though Sydney is almost there). I think having North Adelaide over the river also contributed to the pull towards a northern centre for the city. Whilst elegant and broadly functional, I think "Light's Vision" was a triumph of form over function ultimately, because of it's scale.
BTW Adelaide already has a "Fed Square" thang of its own. All it would take to bring it together is a coordinated marketing exercise. One day it will dawn on people what it is.
