Here is the latest render. It shows a bit of the canopy roof. I am not sure what the rest of the roof looks like (other than what I said previously - that a lot of thought has gone into the view from Scotsman's Hill - so it will not be ugly).
Hard to tell if they are the same panels as the ones in the back. We can official declare that they will not be metallic like the tiles on the NMC or Royal Oak YMCA, but maybe the front panels will have a little more sheen than the panels on the backside
