Living Room, Chair, Ceiling Lighting, and Concrete Floor Like the other buildings onsite, John Hix designed Casa Solaris to take advantage of the natural forces here in Vieques; wind, sun and rain. By creating open spaces, where basically the fourth wall is missing, John created a space that takes advantage of the trade winds that flow through the Vieques hills. By placing the open wall towards the trade winds (to the East), the room is constantly cooled, leaving no need for air conditioning. Photo by Michael Grimm.
