Ben,

we do not have elevations or floorplans posted.  there was a hint at things to come at austinmodhouse.com where I had a small distorted picture of a model that was made early on in the design phase.  but now the pics of the real thing sort of make that modle obsolete. 

we didn't spend time and $ in a bunch of 3d renderings with various color schemes etc.  but we've been very happy with mark's design.

I have no strong opinions on the MDO as of yet.  Mark chose this and it was on site before we even had a chance to do some online searches.  we'd never eve heard of it before.  it was either MDO or hardi and this ended up being a/b the same or a slight bit less.  when I did spend some time searching I found confusing info where some sites said it must be primed and painted.  mark had intended for it to go up w/o paint.  we were not too crazy about the color (craft paper or brown paper baggish) and had pledged to paint it at some later date.  but we also planned to do exposed fasteners and that would make priming and painting later a huge pain. 

so it's now mostly all painted and primed.  I think there will be some flashing that will go between each run and not sure how they are sealing the vertical seams, mabye caulk?  this is all part of an ongoing discussion that never seems to be resolved.

I myself am anxious to see how it turns out.
