This dollhouse was designed very well, and manufactured more precisely than I expected (in a good way). Things went together smoothly and pretty much everything self-aligned during assembly when tightening up screws. 3D instructions available through BILT app made the process so much easier than traditional instructions, with the added benefit of being able to orbit around the model in the app to see different angles for clarifying any confusing steps. I just finished building it and I'm sure my daughter will love it. It seems very sturdy and I expect it will last a long time.
