Ok knowing that and with the logs I have available I can get busy.

Just need to spend a bit of time designing the joints.

The Monterey Cypress will be good for sills because of its rot resistant properties but I'm concerned about using it elsewhere because it is so prone to splitting. Its really easy to make shingles with the stuff but rather hard to nail them down without them splitting. Tenons would need to be extra long to provide enough relish to deal with this.

On the other hand I'm concerned about using the pine as posts because it is not rot resistant. For most of the frame this wouldn't be a problem as long as its built well and kept dry but the bottom of the tenons of the posts going through the sills may get a bit damp and hence rot.
