As with Johnson's Produce, I only have a single prototype photo to work from (taken from http://www.rootsweb.ancestry.com/~mnaitkin/hill_city.htm):
It's been miserably hot and humid here today, so I stayed indoors and work on some plans for the structure. After multiple do-overs, here's what I've come up with for the front:
The side:
I also intend to detail the interior, with a twist - I plan to split the structure diagonally, so that the two walls visible in the prototype photo will lift away, revealing a diagonal cross-section of the interior, right down to the floor joists.
The ground floor layout:
The upstairs layout:
I'll be using Grandt Line windows (50 total) and doors. I haven't decided yet if I'll use scribed sheeting for the walls, or it I'll do the board-by-board siding like I did on Johnson's Produce. I have some experimentation to do before I make that decision.
