Basically, it connects to the existing building (which will lose its fins in the process – the foreground part of the third render shows the building in Gstar's photo) and has retail at ground level, commercial in the brick podium, which will be linked to the commercial space in the existing part, and apartments in the fugly part on top.
I don't so much dislike the brick part of the building. It does fit in well with the Woolstores (there's one pretty well directly opposite, right?), but the upper part should be completely redesigned imo (for the love of architecture, lose the arches!)
And bribri, I'm pretty sure Birkish is right in that they are plans produced especially to gain council approval, but aren't to be used in the construction (which would require a much more detailed set of plans, showing things like the wiring, plumbing, ducting, etc – some of which wouldn't have been finalised yet). Most DA plans usually say "preliminary" on them somewhere.
