You need to install the porch roof before moving on. It's important not to place this roof over the siding, so it should be in place before you start on the front wall and exterior finishes.
Lay the dollhouse on its back to install the porch roof panels. I will paint mine later, once the glue is dry, as I will have good access to all areas after installation. Use a rubber mallet to fit the tabs into the wall slots.
After installation, apply glue along all the joints and ensure that they are aligned and square where the panels meet. Clamp with masking tape and let it dry.
