For my daughter I have built a colorful Pippi Longstocking (Langstrumpf) doll house with plywood and some accessories (3D printed parts). The building concept is modular so you can adapt it easily and let your creativity play.
Step 1: Material and Tools Required
-Pine wood lath22x22mm
-Wood tenons (to connect the triangle wood profile of the roof with the 4-groove-profile)
-Buzz saw/circular saw
