Interesting... Does anybody know how many units are currently under construction and completed? Given approximately 7500 units in total for the completed version of Cityplace, this would (assuming that the number is accurate) give us the approximate number of units in Signature, and hence a rough idea of its size. If the resulting implied number of units in Signature is indeed twice that of the larger existing Cityplace buildings, then who knows, that render might be not too far off the mark.
I dont think that you can make any calculations at the moment, cause rumour has it that Concord Adex has purchased a couple more lots just north of Panorama for a future development. Lets wait and see what comes out of all this.
