who owns the arches under rail bridges?

Are they expensive to rent/buy?

Found an empty one near me, not sure if it was storage or a garage but now its empty and I would like to find out how much it is... noone local knows about it and there is no signs up there.

Its in Clapham London BTW and has enough room to park several cars... I wouldnt mind having it as a lock up and not for business, then I can get what car I want and not worry about parking on the street but instead in a secure lockup.

its not on there and going by usual rent its about £30k to £110k a year so that is off limits, tho someone is now offering a place just up from me at £20 a week at a place which has remote doors and secure parking so might look there instead.
