seem to have done your homework. my next one will be 3 sides of double concrete block, or similar verson, but no direct sun on inside wall. north side of house will be all glass, or close to it, with entire house shaded. flat roof, 2 story, with metal shade roof covering anyting i missed, one hell of a balcony.
my problem is finding a plot of land with good north view, and couple rai, so no neighbor hassles, in the middle of rice paddy land, for R&R and land price. within an hour from a shopping center and i'll be happy.
that north exposure thing is a biggy, will make a huge difference in comfort level during hot season.
good luck, keep us posted.
