Excellent! Thanks for taking the time to investigate this construction, finding
and reporting its real-brick faults, and tackling some corrective design
approaches.

Oooh, 1/2-brick length change. Maybe going for two side-by-side roll up doors
would return the overall length to an integer value?

Wow! Too much CAD time for me.

Great ideas.

Well documented, Alastair. Perhaps your dreams will realize a great solution.
I think this garage door style will look good once we find a good construction.
