This extension (shown at right in top photo), added off the southeast side of the main (large) room, was envisioned as additional space. But more importantly, I saw the need to add a passive-solar gain room to collect sunlight in the winter months. Since a french style door will separate this room from the main room, it could be closed at night to retain the heat in the large room accumulated from the passive solar style design.
In the above photo of the solar gain room, the concrete bond beam (discussed in previous blog entries) is shown at top hugging the curved wall. The stone stem-wall extends up 3-feet from the footing. The room dimensions are approximately 7'x10'. Ceiling height for this space will be about 8-1/2 feet.
