I just built this cute smaller side build to the Tower build of the Creator 3in1 Medieval Castle. It uses only spare parts left over from the Tower build, but I used a few 1x4 plates of my own just to hold the roof together better. It's a little flimsy, but pretty great and adds a lot to the secondary build of the Tower. Elevating it up to being better than the main Castle build vanilla without any MOCing.
Highly recommend building this smaller build if you own this creator set. Check out my short YouTube video I made showing it off, I also include the instructions.
