The top part of the house doesn’t fit onto the roof. The house itself is easy to assemble, except for the roof, which isn’t aligned on both sides, making one side of the roof wider than the other. As a result, the top part (which is supposed to close the gaps between the two roof panels) doesn’t fit.
Brilliantly packaged, super easy to assemble, really, really good quality, although there are a few splinters… I'm super happy.
Shame I can't add a photo.
