Welcome! I have a good grasp on construction designs, being that I owned a construction business for 14 years and was raised in the family construction business. It is my area of expertise even in the design world.
I tried to emphasize the roof idea in these designs to fit your roof in a day concept. Incidentally, my in-laws had a house built using very similar methods. Very cool way to build a home.
I also used the picket fence in a few because that shows the American Dream of home ownership. I also use the pencil lines from a draftsman in some as well.
Paul, I really appreciate the effort here - I like your #17 best - we feel like the logo should be simple, not complicated, modern not nostalgic, clean not cluttered - but it is really hard to know how to describe something you don't have a clear idea of what you want!
I'd love to hear what you think about how to involved the idea of panels into your thinking?
#16 is good too ... not sure I like the tone grade letters, but think the pencil lines are a really interesting idea - that could be interesting to develop - any way to denote CAD vs. drawing board?
