Although Chris, you have a good idea in principle, shared renting of such a garage area can only be mainly of interest to those club members within say a 30 mile radius of the chosen site and then only to those who have more than one BX. Also remember that some have other cars than a BX as their additional steeds so 'BX only' cannot be a mantra. As to the parts storage, well that seems to work incredibly well by the existing 'distributed holdings' of the BX club as a whole.
Phil may have summed up well as follows:

A 'free' X000 sq. ft leak-free barn might be but even then, given how much time is at a premium these days, the distances to cover cost too much in time and in fuel. It makes it unrealistic. For collectable Ferraris or other appreciating classics, maybe someone would be prepared to spend £££'s a year to visit their projects in a dry and secure store... but a BX? Not yet, I'm afraid.
Mulley also makes a good point of the problems of moving a central storage stash if continuation of renting become impossible due to rent increases or maybe exiting contributors.
Your dream is an attractive dream for us all if that facility could be organised in all of our respective localities but the cold facts are that the BX club is spread across the whole of the UK and beyond so there is no 'right' place for it to be.
Best plan really if you want to go ahead is to find interested people in your area whatever their car interests and see if is then viable for your group.
Doc has already done this with his mates and associates so it can work if you find reliable like minded people.
One last caution, do not be lulled into a false sense of security by looking at the membership number of the BX Club and drawing the conclusion that there are loads of members ready to jump for this within your area. The membership number is extremely misleading as many have been spammers, or never had a BX, never posted and others who have been active have since migrated away from BX's.
