The building is 73mm x 97mm. It's modeled after a half-timbered house in Stolberg in the Harz region.
I glued together the walls first and used the wall support frame to glue the parts at 90°. After painting the walls the half- timbered parts (Fachwerkoptik) is glued to the walls (front & back) and the timber cladding goes on the sides. I added the door and windows in the last step.
