3Step 4: Assemble the Gingerbread House

Lay out your gingerbread pieces on a flat surface and plan the assembly. Begin by attaching the walls, piping a thick line of royal icing along the edges where the panels will meet. 

Hold the pieces together for a few moments to ensure they stick, then let them dry for about 15 minutes before adding the roof panels. Pipe icing along the tops of the walls and gently press the roof pieces in place. Allow the entire structure to dry for at least an hour to ensure stability.
