I once owned a 200 year old two up two down cottage with outside loo.
It was a twelve feet wide mid terrace.
It was our weekend home but our neighbours permanent home.
She was a bit arsey with us because she wanted our house but the owner wouldn't sell it. She bought the one next door and then he put ours up for sale and we bought it. so she wasn't happy.
We had right of way over their garden which meant she couldn't build out like we did to make a downstairs bathroom and bedroom. Kids had the upstairs bedrooms.
They gutted theirs completely. They were just left with the adjoining walls and the roof. The upstairs was made into two small bedrooms and a bathroom.
She had to be really nice to us because in order to get her staircase attached the wall it had to come out in our upstairs bedroom ie the ties to tie it in and make it secure.
She couldn't have done what she did without our consent. Being nice people we let her do it.
Then when our extension was built she started rattling her sabre saying our extension was 9 ins on her property. Remember these cottages were only 12 feet wide and the gardens weren't straight ....a bit like a dogs hind leg.
Anyway husband at the time told her if there was any more nonsense from her we would get her stairs removed from our bedroom.
I dont know, sometimes you give some people an inch and they take a mile.
She was cordial to us after that ie we exchanged hellos and I can understand her annoyance but it wasn't our fault.
