Balmy thread to fruition!
35 storeys,(0.6 HA footprint)
So based on the Portsmouth 33 storey tower (0.35HA footprint) which is just over 100m.
The Cardiff tower should then be Wales Tallest

(Swansea one is 107m)

I did not realise that this will be student accommodation for 500.
I hope they put netting over the train tracks to protect from falling objects/students.
