Today, I worked on the roofs of the tower and bay. Take a look at how the inner supports of the tower roof fit together. Normally, assembling a tower roof using the tape method in the instructions can be quite challenging, but for this dollhouse, it worked surprisingly well, and I recommend it.
To join your roof panels, apply masking tape to the undersides where they meet, then turn the structure right side up and glue it to the tops of the tower and bay. Make sure everything is straight and even all around.
For now, assembly needs to pause so I can address some loose ends before continuing. One of these is the hinged panel, which I will work on next.
