Before opening we had to get a new lock put on the front door. As we only had one large key it wouldn't be suitable to give to guests and it's not a key to get copies made easily. Fortunately we discovered the man who made our metal pergola could also put a new lock in the heavy iron front doors.
Have also had smaller locks put on the bedrooms.
As our floors, and many of the walls, aren't straight we've had to improvise with levelling the bed legs in the twin room. There is quite a slope on the floor and the attachment to the wall legs seems to have worked.
