[Cob] Dome Roof + Cob Planter ?

[Amanda Peck]

What kind of roof do you want? what's handy?  what method do you want to 
try? recyled, low impact, round wood, sustainable, living, get the building 
DONE, how much help are you going to have?  I'd forgotten about earthbag 
domes when I wrote the original.

What kind of loads are you going to have, both snow-loads and just roof on 
the building, consider leaks, how far along did you get with the building 
before you considered roofing?

But lots of things--plate at the top, etc. are going to be very similar no 
matter what kind of roof or building you are doing.

But I won't say that this is "just engineering" but finding a solution that 
meets most of the wants and "availables" maintains the integrity of the 
structure is research and questioning brainstorming and allowing a plan to 
come forward.

(I think that the--shed--roof we made for an irregular trapezoidal treehouse 
where the front was fastened to trees, the back built on posts illustrates 
the kind of problem solving that needs to be done--not even sure but what 
Ondura was the least awful material for the building--carrying stuff through 
the dry wash and up a very steep and rough hill with much else sounds 
horrible.  I wouldn't use it again except under similar circumstances--it 
smells bad for a good while)

Exactly in what factors depends on the kind of dome?
