What is an Outdoor Room?

I don’t divide architecture, landscape and gardening; to me they are one.
— Luis Barragan

The interception of the 3 disciplines listed above are so true when discussing truly, functional extensions to a home. These axioms serve as the "proof" of the benefit of outdoor rooms. Since an outdoor room is, well, outdoors, it becomes part of the landscape. These "atrium" gardens were common to civilizations of ancient Rome and Moorish Gardens (with or without water). If the Outdoor Room has shape and human scale, architecture exists. Mating this man-made art with a garden, fulfills the truth of the axiom. Outdoor rooms come from within the home and extend to the natural environment..
