They're just harder to make since you have to use a form to fill in the hole while you're layering cob up around it. With regular rectangular windows, you just lay a strong enough board over the top. There are tons of building in the middle east with arched windows, go for it! Here's one at Ahimsa sanctuary: http://www.peacemaking.org/ahimsawebfiles/main.html > I assume that cob walls are usually built lower > rather than taller so there is not usually room for a > lot of wall between the top of the window and the roof > for a gothic arch (that would not require a header), > and the load on the wall would increase from wind and > seismic forces and incresed labor of more cob which > would usually be more of a problem than most would > wish to deal with. Nah, wind forces on a cob wall are just going to make the cob wall laugh until the wind gets really pissed and comes back with it's tornado big brother. OTOH, seismic forces don't care how big your wall is, it'd be like us caring about the difference between the lifting the weight of a post-it or a full sheet of paper. The taller walls will be thicker at the bottom, so proportionally, it's the same. I'll see if I can find a picture of the gigantic welsh or english farmhouse. I think I saw a picture of it in the Hand Sculpted House, but it's just HUGE. Twelve foot ceilings I think. This isn't it, but it's a 2 story addition in UK: http:// www.cobcottage.com/node/121 > > As for up-lift on the roof, -snip- I think someone else pointed out about putting dead men in the walls as you build the walls. You can simply cut notches in the logs and insert your rafters' ends into the notches. Good luck!
