I haven't posted a photo of the south wall in a long time. It's starting to take shape now. I finally have all the lintel (beams) above the doors and windows and now can begin to add cob to the walls without any significant interruption until roof height.
The larger window at the center of the photo will provide passive solar gain to the 'main room' during the winter months, when the sun angle is lower in the sky. The wall height in this room may reach 12-1/2-ft. The studio itself is a relatively small structure, so to create the illusion of a larger space, I selected the large window and the 12-ft ceilings in order to achieve a sense of 'space'.
