Hi Julie! Welcome to the forums!
The Orchid was/is my first dollhouse -- and I've just finished it (for now, that is). Once you start to figure out how things go together and what order you want to go in, it is nice and straightforward. (For example, I prepped and assembled the windows, set them aside, finished the floors, painted the exterior, papered the inside, assembled, installed windows, did touch ups and finishing stuff.)
I read that you were wondering about the overall footprint of the Greenleaf Village, so I went and found a tray (18 by 11 inches) to see if my in-progress Village would fit on it. It does! I've got photographs in my gallery, if you'd like to see them. I bought mine from miniatures.com. The shipping was reasonable ($16 total for the travel trailer, adams, and village) and they arrived quickly. To get to the point that I'm at now, I spent about 3 hours punching, sanding, and glueing the pieces. I've had them taped together since then, just took it off for the photographs, and will likely paint a few tonight while I wait for the bedsheets to dry. Very easy, so far, and a good level of detail.
