These are small versions of the Maxis “Realistic Princess Castle” and “Modern Life” dollhouses, scaled down to a more manageable size. The Victorian dollhouse at half the original size is available here.
Textures are referenced from the originals. They cost 200§/485§, four colour variants each, same tuning as the large versions. Object states seem to work fine from what I’ve seen.
Polygon Counts: Like the original minus group 1 (dropshadow mesh, which is removed in these since it can’t be scaled by way of editing the rig).
