Buildings, buildings, buildings... So many different kinds. It's a little hard to keep track of them all, so I finally broke down and threw together a visual list of every major building type I could find. It's a little bit bigger than I expected actually... No real particular order to the buildings in the list other than the order I saw them in while going through all the ref files. This only includes buildings seen between the start of Season 1 and Hearths Warming Eve. More buildings will added once I get a chance to go through the newer episodes. In any case, hope this helps those of y'all who are actually modeling Ponyville buildings and such. Shorah!
(Note: I did not include all the different varieties of bridges, market stalls, and rainbow tents. They may or may not be added later as needed.)
