The next set I am working on is a Tropical or Pirate Island Village. Here are some concept sketches.
The look will be wood (and maybe later bamboo) architecture with palm frond roof. For the Caribbean Island version I will use bright colors but there will also be a plain wood version too.
With the core elements and all the possible way to add extensions and also with all the texture and color variations you will be able to build tropical villages in any size with basically unique looking buildings!
