update roof
now its really quite symetrical not so sure about that ... I tried to keep it relatively straight foward though, north the background flatness- straight gridyness- south 3-dimensional foreground articulation and some formal curvature- corner as connection point - east and west is here still the same- transition zone ... guess if I articulate east and west differently will give me a different picture of none symmetry .... it looks a bit like elliots now....that happend kind of during the way- I just realized later... hmmm ... was working on section now... 2d flat north 3d program south...

AS a first step in modifying the frame it's fine that it's symmetrical - effectively you're developing a new generic. Don't necessarily worry about forcing east vs west to generate asymmetry. Remember you still have the sun and where/how you locate program that will require local thickenning or deviation in your roof structure. (and it doesn't look like elliott's :)
I hope you have a document for the TS showing how it evolved over all the stages of contextualizing.
book some time on the laser cutter to cut this version, so we can then also have the first model, the stages in between and the next version which should include program, etc.
