The front wall comes in two sections, so make sure that you join the top and bottom parts tightly together for a smooth surface. This joint line, visible in the pictures, will be hidden with the porch roof.
The front main roof also comes in two sections that join in the center to make the left and right sides. I clamped the two joining parts tightly together and let the glue dry.
As you're building the outer walls, partitions and main roof, I suggest you do each assembly right after the other, not allowing the glue to thoroughly dry, between steps. This will help you position things better together before clamping and letting it dry.
I used wood glue on all the joints so the structure of the dollhouse is sturdy. You might have to tap with a hammer to fit tabs in place.
The instructions prompt you to put the trims on the windows and doors first, but don't. It will only cause you a lot of problems in the paint and wallpaper stages. Just leave all trim for the end. There will be no obstacles in the end to put the trim on, both exterior and interior.
Right at this point of the dollhouse's construction is where you have to stop and begin finishing certain parts. Do not glue the back roof yet. Leave that for the end. It will only make wallpapering difficult.
Wait until the two joined pieces of the front main roof finish drying before gluing the two front side gable roofs.
To minimize difficult cuts, I suggest you do all of the wallpapering for the second floor now, before installation of the roof panels. You will need to mark them well so you do not confuse the wall sides with the roof sides.
