A few years ago, a friend asked me to design a carport. Now, you don't need an architect with twenty five years experience to do that. I told her sure - but I would really work to make it interesting and more than mundane. If when she saw it, she didn't like it... I would understand.
Agreed, she said.
What I thought of was a "covered bridge" type of structure. A simple shed roof and "walls" made of 4x4's that were bolted together with strap connections to form a large truss.
She liked it, but of course the contractor talked her out of it. Ah well.
