Ouch - that looks really high density. The existing buildings have plenty of space between them and in their internal squares, so they look quite 'leisurely', but this looks like every possible square metre of plan space has been used.
That "public" square's not going to get much light.
And I noticed that they show the existing Elisabeth House shape, rather than any indication of the proposed, taller new buildings.
I would guess that having such tall buildings on both sides of York Road might turn it into a dark, windy canyon.
