Garage/Units to hire/rent

Does anyone know of anywhere to rent or hire a garage or business unit for a day or weekend? I really want to give the car a major detail and correction but would love to do it inside somewhere with the dark nights closing in.

If anyone knows anyone or anywhere that could accommodate this it would be appreciated.

Yeah I pass that on the way to work every day, but not really ideal for detailing.

Have a couple of mates that work at garages so will ask them, but cant see them going for it.

My aunty has a huge double garage but its full of crap, might ask her if I can move all the crap to one side.
