Once the fences have come down, the area could do with a resurvey. 
The Old Mining Building has been renamed as the Bragg building, which will be home to Physics (and Computing I think). A large new building has been built behind the Old Mining building, with a covered bridge into Chemistry West. Some of the mature trees were chopped down and have been replaced by saplings. Also I think the paths/service roads have been reconfigured slightly. The steps into St George's field next to Chemistry West have been removed and replaced with a ramp.
