yes very good advice we did much the same, had the land then made the plans with the builder, my Thai wife did know the builder, he had a contract drawn up with progressive payments, we came to Thailand for three months witch in that time the house was almost finished minus painting and finishing touches, wife had a friend who watch over for us and sent videos of progress,all went well but was in 2019 so we could not get back for nearly 3 years Covid. We are just so pleased, just what we wanted.
