DL -

Thanks for the long reply...

While the math and proportions all make sense... I guess I'm more interested in how the geometry meshes with real world program - room sizes, door sizes, bathroom sizes, etc... (and we haven't talked about mashing code requirements into this...)

RE: the windows - have you studied the sun and orientation? Does wheel geometry conveniently make placement so that winter sun can warm the interior and you can be shaded by summer sun? Was the overhang length chosen by the wheel or by sun angle and location on the globe?

I've come at design from a very different side of the problem - orientation / use / program... and then the limits of site / geometry of various materials are used to affect the overall shape. As someone with an art / sculpture background who drifted to architecture - proportion / limits / systems are fascinating to me... hence my questions.
