The two sheds will be demolished within a couple of weeks. If the double glazed uPVC windows/door, or the wood from the buildings is any use to anyone, they're yours if you come and remove/help to dismantle them. Wood is in pretty good condition (green paint on the smaller shed is tatty, but the wood beneath is not rotting).
Door/window measurements are width x height of the frame as a whole.
Door: 83 cm x 196 cm
Window 1 (two openers side hinged): 115 x 70 (without the sill)
Window 2 (ditto): 117 x 68 (ditto)
Window 3 (not in photo), single double glazed pane, no opener: 175 x 100
