As a designer that specializes in Tropical Architecture, I come across the term “indoor-outdoor living" on a regular basis.  What my clients are referring to is that they want the outdoors to flow seamlessly with their interior environment.  Not surprising of course, this style is increasingly popular in tropical climates.  The idea is to slide back 20-30 foot glass doors that remove an entire wall of your room, allowing panoramic views of the great outdoors.  Although this style of design does open your house up to nature, many don't contemplate the need for screens in areas such as Panama, Costa Rica, Kauai, etc., where rainfall keeps the mosquito population healthy.  This completely open-door design style works best in dryer climates such as Kona and Poipu, Hawaii for example, where mosquitoes aren’t a problem.  Designing a home to be practical is as important as to be beautiful.  So if you plan to live in a wet tropical area, it is important to understand that you can still have an open feeling home, allowing for expansive views and the tropical breezes to enjoy.  You just need to be smart in designing the right doors for the right climates.
