what does not need to be in walls in clash of clans

TL;DR

In Clash of Clans, you don’t need to put non-defensive, non-resource buildings inside your walls—things like Barracks, Army Camps, Builder’s Huts, Laboratories, and decorations can safely sit outside. Priority inside walls goes to your Town Hall (if you care about trophies), defenses, Clan Castle, and storages.

What doesn’t need to be inside walls

Based on long-standing community strategy and base-building guides, the following buildings are commonly placed outside the walled core because they don’t give attackers a meaningful advantage if destroyed:

  • Barracks (and Dark Barracks)
  • Army Camps
  • Builder’s Huts
  • Laboratory
  • Spell Factory / Dark Spell Factory (often grouped with “production” buildings)
  • Decorations (trees, statues, etc.)
  • Sometimes Clan Castle is debated, but most players keep it inside to protect troops; however, it’s not strictly required if you’re using a specific lure design.

These buildings mainly:

  • Contribute to your destruction percentage (which can help attackers reach 50%+), but
  • Don’t hold resources or deal damage, so there’s little strategic gain for attackers in prioritizing them.

Community consensus: “Buildings like the army camp, barracks, laboratory, etc. should be left outside the wall. The enemy will use time on destroying them.”

What should be inside walls (for context)

To make the “what doesn’t need” part clearer, here’s what most players do protect with walls:

  • Town Hall – if you care about trophies; some farmers leave it outside for free shields.
  • Defensive buildings – Cannons, Archer Towers, Mortars, Air Defenses, Wizard Towers, X-Bows, Inferno Towers, Eagle Artillery, etc.
  • Storages – Gold, Elixir, and Dark Elixir Storages (especially if you’re protecting loot).
  • Clan Castle – usually inside so enemy troops can’t easily lure and kill your clan troops.
  • Heroes – when deployed, they’re best protected indirectly by keeping key defenses and storages inside.

Why this works: the logic behind it

Attackers generally focus on:

  1. Resources (storages, mines/collectors early, though mines/collectors are often outside too).
  1. Defenses (to reduce troop losses).
  1. Town Hall (for trophies or in war/league contexts).

Buildings like Barracks and Army Camps don’t feed any of these goals, so:

  • They’re great as time-wasters on the outside.
  • They help push the attacker’s troop pathing and waste seconds, which can be crucial in time-limited attacks.

As one guide puts it:

“Everything other than storage+defense can be on the outside. If you manage to have extra walls after your prioritization, it’s best to put up multiple layers of wall, rather than just one.”

Mini base-building checklist (for walls)

If you’re short on walls or just optimizing: Inside your main walled area:

  • Town Hall (if trophy-focused)
  • All defenses you can fit
  • Storages
  • Clan Castle (usually)

Outside the walls (fine to leave there):

  • Barracks / Dark Barracks
  • Army Camps
  • Builder’s Huts (often in corners to spread the base)
  • Laboratory
  • Spell Factories
  • Decorations

This setup maximizes the value of every wall piece you have while still making attackers work for high destruction.

Bottom line:
In Clash of Clans, you do not need to put Barracks, Army Camps, Builder’s Huts, Laboratories, Spell Factories, or decorations inside your walls. Focus your walls around defenses, storages, and (optionally) Town Hall and Clan Castle, and let the other buildings sit outside as time-wasting “percentage filler.”
