It's nice to see that the latest version got a height increase from 160M to 170M.
I'm thinking that's some marketing - get people to see what you want them to...
If this happens as 2-tower developments usually do, shortest tower first, then one-up themselves with Tower 2, well, they went from what was 37 and 48 storey towers to what appears to be 28/29 and 50/51 storey towers - reducing the entry cost of what's on the table now, and when they build the 35 to 40 storey Tower 2, it still one-ups their shorter tower.
I won't be holding my breath for a 170m tower but I guess you never know.
