I'm working on the plans using Google's free 3D program SketchUp. I'm planning on building with aluminum studs vs. wood 2x4's. One of the major considerations when building for a tropical jungle climate is mold. I'm also researching wall materials that are healthy for the environment, as well as resistant to mold and rot.
Security while we're away is also a big concern. In the screen grab above, you can see how the deck will fold up and lock, blocking access to the sliding door-wall.
The windows will likely have some sort of metal mesh as well.
Or better yet, I can use 1x1's to make a cladding that would double as a railing for the upstairs porch/green roof. Thats the magic of SketchUp. So easy to plan and make adjustments before you start the real construction.
