My husband and I made this for our daughters' calico critters, which they received for Christmas. We wanted a house with few walls, so that all 3 girls could play simultaneously. We used Ana's dream dollhouse plan, but scaled it down to half the size. We also modified it slightly to fit what we needed.
This is just the perfect size for smaller toys like Littlest Pet Shop or other 3 to 4" tall toys.
This was our first build together and so it took us a while to do. For someone with a bit more experience, who also has all their materials and tools ready, this could be finished in 1 day or a weekend.
