The rendering suggests that they've learned from their East Market experience when it comes to mixed use. One of east Market's failings is that the ground-floor retail should in fact be as tall as the first two storeys - it is too low and the building (especially phase III) looks as if it's sqatting on its retail. (I'd be interested in seeing whether someone, one day, will buy the second-floor corner unit in Phase III, drill a hole in the concrete, put a staircase in and have a nice two-level store in the corner with extra windows).
Central looks like it has an appropriately higher ground level. Good.
