As for the building, it's a combination of corporate cityscape style (see most of central Leeds) with a smoked glass 'feature'. The corner's a great lesson to us all. When you really can't decide to do a curve or a sharp corner, do both!
My correspondent on this one coined a beautiful phrase to describe the checkerboard facade treatment and gives an eye witness' detailed critique: "If you notice on the second image, those bizarre vertical bits of fridge magnet cladding are a different finish to the other cladding elsewhere on the building. Otherwise, it looks like sketchup. Exactly like sketchup." I couldn't have put it better myself.
