Well it's my understanding that piling is underway for 2 resi developments that watkin-jones are constructing at central quay between old brewery building and the river. Plot 1 various heights but upto 91m 30floors - Plot 2 various heights upto 64m(ish) 20 floors.
Whilst the curran road tower (gramercy) is already underway - it'll be 85m I 'd be surprised if the plot 1 tower at central quay doesn't overtake it for the claim of Cardiff's tallest!!

Incidentally it looks like - further down the line 2 more towers planned for central quay - another the same size as plot 1 and then one on corner with penarth road of 42 storeys! that's 125m
