Random question: does anyone know what is inside the long building that makes up the back of the south stand? The stands are sort of tacked onto the pitch side of it, but there is an actual building that runs the length. There is also a garage door on the south side, as shown here in this pre-Cavalry 3D Google Maps view:

The obvious and boring answer is "horsey things", landscaping vehicles, etc. but I was just curious. Or maybe it is Shermanator's private reception lounge to which I have not yet been invited.
