Thanks carlbraun, I can't really answer most of that. The cement was the right stuff, I sent some deliveries back. Yes, the bar could have been a bit thicker in places. I put a certain ammount of trust in Khun Sing and Khun Lee, who make walls for a living. The others double as Farmers and Taxi drivers. The electrics were done by Cowboys and they did not like being told to 'bladdy do it again', by a Farrang with a cert. in Health and Safety issued in another country. If I could/have to do it all over again, I will do it myself when no one is looking. But I am ahead of my self....
