Town Hall 4

Now we get to the point of variation. To start, I'll use a base designed by XxGenocidexX, at a level 4 town hall.

Honestly, not the best I've seen. To start, it keeps non-essential buildings inside the walls, that would be the builder's huts, the lab, and the barracks. Second, the Elixir storage is completely out of range, providing easy resources to any player who attacks. Third, and this is would be partially solved by fixing the other two, is the infective use of walls. Because of the one square zone around all buildings, there is an empty square directly below the mortar. This allows the attacker to swap troops inside the walls, and wreak havoc without being in the line of fire waiting to destroy a wall. However, the location of the town hall is good because it looks to be minimally defended, but is actually covered by three defensive buildings and the Clan Castle.

All in all, I recommend something closer to one of the following.

In this design, barbarians and goblins will end up almost circling completely before trying to get to the middle, providing ample time for defenses to destroy them. Archers and giants however, will target the middle shell as well as the outer one, and could prove effective. Mostly though, it works fine.

When I used this layout, I had successful defenses, and ones where the attacker got one star, but no substantial resources. note the location of the spring trap, it often took out a few giants before they made it to the mortar.
