Glass House with Floor. This one would be perfect in Ocean Shores because who cares if it is rainy, it's so much more awesome than sitting in the trailer. A little table and cozy chairs, some wall mounted candle holders and seashells mounted on the frame.
great passive solar design- I would plant row of deciduous trees in front of glass so that in the winter that could act as a giant trombe wall but be shaded to keep it cool in the summer. Trees that max out at 2 stories would allow south face 3rd level roof to accommodate panels!
