I have been to St. Fagans at least 4 times and just about saw it all by then end! Certainly you need more than half a day! Also, since I moved up here, they have added a lot to St. Fagans, so I’d likely need another day to see that!!
Yes, but unfortunately they tend to be very expensive to maintain. You need lime mortar and proper slate or thatch. My cottage was almost modern by St. F. standards, but I just couldn’t afford to keep up with all that needed to be done!
Oh, and my immediate predecessor had put in a bathroom upstairs, with toilet!
