After starting these houses, I did find other collections on archive.org (through Pinterest, which is how I found the Home Builders Catalog in the first place), and have even worked on a house from one of them.
From the "Book of Homes * L. C. Andrew", copyright 1929. Design 691-B. I'm still working on the interior (furnishings on the top floor, some lighting, that sort of thing).
Awesome! The picture sharing page I'm using is actually working! [:D]
Okay, I actually have a few homes from that collection that I'm interested in possibly recreating as well. [;)] Possibly I'll work on those and hopefully start a whole thread on them as well? Who knows.
