My first thought was that it wasn't that big but comparing it to the building in front it looks to be 4 or 5 storeys to the start of the roof and another 4-5 storeys to the apex. That's quite big. One thought was that it might be the Chinese factory where all of Axminster's machine tools are manufactured but they wouldn't require the height and I doubt if they would put if over several floors in preference to a larger single storey building. So what does require that sort of height? The Leibherr crane depot behind where I work is big - but not that big. And they have some pretty big cranes in there.
