One of the sites i'm currently involved with has an old meat processing plant on it, which is due to be stripped out beginning of next week.
The building itself is approx 100'x40', and has been fitted out with various areas inside for storage and processing. As i understand it the building no longer meets hygiene regs for commercial processing, so the contents are most likely being sent off site as hazardous waste.
Inside is packed out with insulation and wipe down walling, and there is also at least one cold store with it's own chiller unit, approx 8'x8'.
The site is located just outside Holyport, near Maidenhead.
If there is any interest i'll have a chat with the contractors and see what i can source.
Any electrical coolers are likely to be 3 phase, and no idea if they work- building has been left for several years without use.
