It all depends on the architects drawings, the specifications of the home, the location and the materials chosen. Costs in construction vary according to these factors. It could be 15,000 baht per sqm, 17,500, 19,000, 25,000, 40,000 etc.It is impossible to know accurate cost to build without finished architects drawings and a full list of all materials and quantities You can build a 250 sqm house for 3 million baht plus vat (7%) or it might cost 5 million, or maybe 6 million or even 10 million.
It depends on the design and materials. The only way to answer this question correctly is to have finished architects drawings and to know exactly what materials are chosen. Also location plays a part too But a good guide to have a home built a professional building company (*essential in Thailand-beware of builders who have no office, no references, no registration and little experience) for a reasonable standard home with reasonable materials grades would be anywhere from 15,000 - 35,000 baht per sqm Also remember it depends hat you include too in the price: Bathrooms, kitchens, tiles, wooden floors, pool etc The best advice anyone can give is to work with a professional registered company with an office and a web site.
It shows they are serious and their guarantee will be worth something. Work with a Thai architect who speaks English and get your architects drawings done first. Then you can know accurate cost to build a house in Thailand.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
