I have no faith in Phoenix whatsoever. They have a history of poor to mediocre projects and they opted for the safe 27 storeys instead of pushing for more.
Prediction for Dworkin's;
The residential floor plate (16,925 square metres) is likely on 48 floors (leaving the third floor of the podium for amenities).
I'm hoping that It is in fact 146 meters, but I'm thinking the same as you guys; typo on the part of OBJ.
