They have been changed twice already, according to the application. And that also says the single fin we see on the hotel is another mock-up for inspection, at scale/location.
The images of the latest version submitted do look better than the previous versions jrb and others took photos of. The edges are thinner and look less freyed, and the fixings more flush and better matched, and the finish looks more metalic.
It kinda confirms something I have been saying, they are relying on scale and distance to hide any sins.
It is clear from the summary though, the planners had similar issues and thoughts as a few here did, and pushed for improvements in the fin finish, and the fixings (nb
@supercity88). As they did on the louvers, which resulted in the perforated panels, and the change to the glazed spandrels (which I did acknowledge was a big improvement when they 'suddenly' appeared on site different to the mock-up). Which explains the taking the panels away and reinstating them with a (slightly) different version.
A couple very simple colour changes, would have made such a big difference, particularly avoiding the dark grey edge to the sails.
It is what it is though, and I welcome the improvements made. Both the spandrel one and the louvers one do have a notable cost increase to them as well, worth pointing out.
