I completed the dormer roofs by gluing them on and covering them with sandpaper, using the same method as the front two. I added interior trim, ensuring it fit snugly around the openings.
I installed the remaining exterior brackets, finding spaces for the extras. I added an extra roof bracket and corner trim near the kitchen bay roof and on the right side tower wall. These brackets were initially tricky but became easier to install.
On the left side of the tower wall, I installed the final white vertical trim. Since the dollhouse corners were notched, I created a matching notch piece from sheet scraps to maintain consistency. I finished shingling the area around the left side tower wall, using long scissors to reach difficult spots. Although these areas are mostly hidden, I made sure to complete them thoroughly, believing that detailed viewers would appreciate the full finish.
For the tower, I added shingles using the same template method as the mansard roof. I emphasized the importance of installing all vertical and horizontal trim before shingling. I wallpapered the tower roof and installed the window using a modified approach. The tower window installation involved using the flexible roof instead of wooden sides. I laminated the interior and exterior trim, glued the sill, and carefully assembled the window. I covered the roof with sandpaper inside and out to ensure a clean look from all angles. I noted that while the tower window lacks interior trim, I planned to create a custom trim later.
I extended the shingling to the back areas of the third floor for a more complete appearance. I personalized the third-floor fireplace by painting it gray to resemble stone and adding printed brick paper to the interior. I also added trim around the interior doors, making minor adjustments as needed.
