I bet even money that Monty could make these.
Shingles, custom split extra wide like those from fresh cut green redwood and then allowed to dry flat out in the summer sun, then nailed in with predrilled holes, maybe with a wide flat washer on each nail, otherwise it'd split fersure. Oh, and making those outer eaves with a bandsaw. Doing these really looks like a lot of fun.
What a great kind of wintertime bunch of projects these could be for carpenters who get very few jobs in wintertime! Not only fun, but they'd sell pretty well, plus show off the skill as the best kind of advertising, be great practice, and a chance to work on some of the little ornamental nice things that some folks may want on their new house. Windows with real shutters and a planter under them, jigsawn trim, custom made round windows, extra steep roof with a windowed gable. Things like that can really raise the value of a real house that is not made fanciful but uses some of the skills that these can show.
