Installation of Second Floor Partitions and Walls
You can add more walls to the dollhouse on the second floor without needing to install the staircase first. The placement of these walls will not affect the staircase installation. By adding walls now, you can start finishing the rooms while you work on the foyer and staircase.
I installed 'Partitions #4 and #5', which were very easy to put in place because there is ample space on this side of the dollhouse, as the 'Right Wall' has not been installed yet. No tabs needed to be cut, and a mallet was not required for placement. These partitions do not obstruct access to any second-floor rooms, allowing you to finish them easily.
Next, I installed the right wall, all the tower walls, and the back wall. Use tacky glue for everything, then apply wood glue along all joints. Secure them with masking tape and let them dry. While you continue working on the foyer and kitchen sections, these walls will be drying and ready for you when you are ready to work on them.
