I think it's a disgraceful situation.
We are also in London, and have a 'share in freehold' flat, which we were delighted to get a few years ago, as the majority seem to be leasehold.
Even with our share in freehold, there are so many ridiculous rules we have to abide by, and things we are not allowed to do.
We are not allowed a dog under any circumstance.
We are not allowed any other pet without asking permission first of the management committee, and gaining permission - we do not know of anyone here who has been successful in gaining permission.
We are not allowed on the majority of grassed areas.
We are not allowed barbecues.
We are not allowed access to our attics (if we are in a top floor flat).
We are not allowed to make any alterations to the windows without permission.
We are not allowed to put a welcome mat outside our own front doors.
We are not allowed to keep a pram anywhere in the large communal areas.
The document of rules is several pages long, so there are many more than listed above. It is the biggest load of bollocks I've ever read in my life, and I'm not surprised that most people living here look fucking miserable all the time. It's incredibly expensive and you can't bloody do anything!
