The second floor:

This floor can be used for your children  or guests. The open ceiling goes right into the wood structured roof. Like a cathedral. The roof is standing 10cm over the wall, so you have a permanent airflow to keep humidity low, even with closed windows in raining season.
You have two bedrooms like this. Both of course with air condition.
And behind that door, there is a huge terrace with a view even greater then down.
A stylish bathroom with toilet, Shower and basin.
There is also a kitchen in the big living area.
