900sm floorplate lets you do those good unit layouts.
Overall: this works well. Ground floor looks generally well thought out, podium interface is good, architecture works well. I appreciate the POPs space which looks like it will work well and the landscape plan looks great with a large number of street trees.
A couple of quibbles:
I don't appreciate the res lobby for the small corner building being on the corner. That should be a retail unit or at least have the "program space" on the corner instead. I'd be tempted to just leave the rooftop addition off as well and let it stand on it's own original form - make it a commercial office building (brick and beam is in high demand after all) and let it stand on it's own. The res addition is pretty marginal, do a 52 storey tower to make up for it if you have to.
That Type G space is also not practically going to be used - I appreciate the attempt to keep it having a minimal impact on the ground floor plan, but loading in reality for Type G will end up happening in the lane as navigating into that space will be too difficult - the margins are exact and it's a difficult, unusual turning movement, which means most drivers likely simply won't bother.
