John (i8)

John is a simple dome design; the neatly organized combination of regular polygons like the perfectly flat perfectly square flat roof pitch and the equilateral triangular panels making a regular hexagon tiling patten sits pleasingly on a  wall structure with both a double square rectangle and a square and rotated square build up. 

Basically it requires no offcuts even though it one of the IGLOOs that requires skilled labour is is relativly inexpensive; due to the attentiveness of the design approach.
