I have a place coming up in a couple of months as a rough idea - I've had 4 lotus cars in there before with room to work on them I'm close to Beaconsfield
Sounds interesting chap...Are there any available units next door/opposite too!? I have client's itching for me to set up a base near there for storage/looking after their cars.
Only one lock up im afraid - access is down a country lane - and quite discrete which is why the previous guy liked it - I can pm you a couple of photos as access could be tight into the lock up - depending on the car !
