I'm confoosed ... you're leaving permanently for Thailand? I was reading your other layout thread, that's abandoned? well at least finishing the room for the layout now means you have a nice finished basement as a selling point.
Two houses... live in the US, but we take long vacations in Thailand where Joy is originally from. Long story short, we were given her mom's land and are building a (small) house there. Joy's mom will live in an apartment on the first floor while we have a summer residence on the second.
The floor plan of this house is tiny as it is in a very urban area. I sketched some ideas, sent it on to an architect there and he finalized the plans. I'll post them later. Total living area for the second floor is 650-750 square feet, almost the same size as my layout room back home.
Needless to say, any layout in Thailand would need to be very small.
