Here's a version of Builder Hall 9 that I've tweaked to make it more effective against 3 stars, especially in terms of placement and also the way minions work in a defensive direction. If you own a level 9 builder, this base will also help you withstand the attacks and get as many victories as possible.
NOTE: You can clone the base directly using this link but understand obstacles will prevent structures from being placed - if your village has grass or many other obstacles in your base , you may have to rebuild works like the above sample base manually from the image we have provided above. Link copy me below. Don't forget to leave feedback on this template base.
