[Cob] 8 sided structures

[Brad Calvert]

>Cat here......  Also look at 8 sided structures
they give the most space for the least amount of roof and foundation!  Very
cost effective as well as labor saving!


A circle is better.  100ft of wall could be used to make a square 25 * 25 =
625 sq ft.  Or 100/(2*3.14)= 15.9ft radius circle = 796 sq ft.

I figure an octogon gives you 754 sq ft
