Well no, you see it is a weird type of lease.
If you can imagine a row of three, two-storey houses, terraced, but each floor is a flat with it's own front door etc. I have one of the 1st floor ones, my lease is a "peppercorn" lease, which is a lease in name only and is as near to freehold as you can get when effectively hovering 10 feet above the ground!
There is nothing in the way of maintenance, ground rent etc. The only stipulation is, the guy downstairs is responsible for everything up to the underside of my concrete slab, I am responsible for everything from the underside of my concrete slab upwards. I.e. he looks after the foundations, I look after the roof. The land is owned by the owner of the flat underneath me. However, as far as I recall, the parking spaces and gardens (we each have one about 7m by 4m) are freehold. We don't have a landlord as such, not even the council.
I suppose I had better check this, means getting out the deeds though and all the legal guff that the solicitor gave me.
I wasn't seriously going to clamp anyone, that's asking for trouble. Anti-climb paint on the doorhandles mind
