I bought a house in the schedule it said with a garage, the missives have been done with the schedule particulars as being WHOLE AND ALL. Scottish Law. It turns out the garage I was shown is not in the plans of the house. So I have paid for and not got a garage.
The person to ask is your solicitor who done the conveyancing on your behalf. Maybe the garage is sited at another location? Sounds like you have a just complaint otherwise.
