The old Merchant Venturers Trade School (and, like Batholomew's Hospital at the bottom of Christmas Steps, once also home to the Bristol Grammar School) has a surprising modern multi-storey roof on the top of it that I'd not really noticed from ground level. I guess the developers wanted to wring as much money as possible out of it when they converted it to flats.
