I recently purchased a set of four plans in a lot on eBay. I’ve since resold the other three, but this house is why I bought the lot in the first place.
Its footprint is 2′ x 2′, which is pretty impressive for the amount of detailing involved. What an interesting structure!
I could see it being done to historical perfection or modernized on the inside as a museum. I wonder if there are any built versions out in the world. :]
