This is some sort of old, abandoned Hoover plant over in Ryde. It's a great spot - this looks right over the water, and expensive apartments are being built on the banks of the river opposite. Other old industrial sites next door have been flattened and turned into flash apartments.
I thought about sneaking in through an open roller door to have a look around inside, but thought better of it. The place is probably haunted by prototype vacuum cleaners that never made it into production.
