A family member owns a flat in London. It's ground floor and the upstairs flat owners hold the freehold. There is a condition that ground floor owners will pay 50% of any associated building repairs to freeholder. The roof needs repairing and instead of just re-roofing the upstairs owner is adding a loft extension and is passing on 50% of this cost to owner of lower flat. Are we BU to think this is CFuckery at its finest?
