Second the builder gives you a price to include everything including materials. I went that way and I really think the builder lost out. In fact post build he actually said that he should have put an extra 500,000 Baht on the price as he did it too cheap.
I did same and I know our builder lost out. He knew it too. Plus he should have charge hazard pay as my wife was on top of the entire build and there was no cutting corners.
I highly encourage the OP to set up 4 installment payments with 50% being the last payment AFTER walk through is agreed on.
