Master CoC base building in 2026 with these universal principles — diagonal compartments, spread defenses, and buried Town Hall — applied from TH9 to TH16.
Quick Answer: Good CoC base building in 2026 follows three universal rules: bury the Town Hall deep, spread defenses across all four quadrants, and use diagonal compartments. These principles apply from TH9 to TH16. Browse BaseCOC by your TH level and copy in one tap.
The 3 Universal Base Building Rules
Rule 1: Bury the Town Hall
At every TH level, the Town Hall is worth exactly 1 star. Always bury it behind the maximum available wall layers.
Rule 2: Spread Defenses Across Four Quadrants
No clustering — spread your highest-DPS defenses evenly so there is no obviously weaker side.
Rule 3: Use Diagonal Compartments
Square compartments create straight paths. Diagonal walls force direction changes that cost attackers time and spell coverage.
Base Building by TH Level

Common Mistakes at Every Level
Traps in obvious corners — Place traps in Root Rider paths and natural army corridors.
All walls on the perimeter — Inner compartment walls matter more.
Heroes clustered together — One Freeze Spell disables all of them. Spread them.
Not updating after patches — Supercell rebalances every 4–8 weeks. Check BaseCOC after every update.
