We are presently doing some deep rethinking of the design in floor plans to improve the use of the south-west floor areas and possibily reduce the number of exterior entrances from 3 to 2. Will present floor plans and other details after we get the permit. Meanwhile, experimentation with the roof has produced the following design with clerestory windows into the attic. No energy analysis has been applied to this increased exterior surface area and glass, but hopeful it will prove positive. I find the south facade too busy now, so this needs attention. One good thing energy-wise would be to remove the entrance from the south facade, as it gets in the way of the south glass. The west side would be a good place to have it - but perhaps thats too uninviting?
