The walls will be QCon blocks which are meant to have insulating properties, we will have foil under the tiles on the roof and I believe building up off the ground should help as well. Hopefully I will arrive in Thailand before its too late to install some sort of fibre in the ceiling as well, at this point in time she who rules is a bit reluctant as it means spending some "extra" money, so if it gets installed I know where the extra will come from.
At this stage we only intend to have 2 air conditioners, 1 in the main bedroom (for me) and one in one of the other bedrooms mainly in case we have farang friends over for a visit.
Work has started again and here's the latest progress.
to be continued.....
