Something like a modern version of the Distillery could work well. Highs and lows with tight floorplates vs. a sludgy mass that fills space and leaves little for the pedestrian. The latter, in fact, is what kind of scares me about the recent Bjarke plan for King Street: we're pretty sure that BIG can pull off such a scheme but what happens when the Kirkors, G+Cs and P+S's start their neanderthalic aping?
