COC Bases: BH4 All Layouts (Builder Hall 4 Base Designs)
All Builder Hall 4 layouts in one place — defense, farming, trophy pushing, and balanced Builder Base designs to help you win more battles.
Builder Hall 4 Base Layout Guide
Builder Hall 4 introduces a more demanding stage of Builder Base design.
Compared with BH3, you have more structures to organize, more defensive coverage
to consider, and a wider range of possible attack approaches to prepare for.
A well-planned BH4 base layout should protect important defenses,
disrupt troop movement, and prevent attackers from reaching several valuable
buildings through one simple entry.
BH4 battles still take place on a single defensive stage, so the complete base
must work as one connected layout. Walls, defenses, traps, and non-defensive
buildings should support the same plan rather than being placed independently.
A suitable layout can help limit stars and destruction, reduce trophy losses,
and improve the Builder Elixir earned from defensive results.
BH4 Defense Layouts
BH4 defense layouts focus on protecting important areas with overlapping defensive ranges. They use walls and surrounding buildings to delay troops, separate groups, and prevent attackers from moving directly toward the Builder Hall or an exposed key defense.
BH4 Trophy Layouts
BH4 trophy layouts are designed to make stars and high destruction more difficult to achieve. They often use offset entry routes, protected central areas, and carefully spaced buildings to increase the distance attackers must travel between important targets.
BH4 Progression Layouts
Builder Base attackers do not steal the resources stored in your buildings. Builder Gold is earned through attacks, while Builder Elixir comes from defensive results. A progression layout therefore aims to limit enemy stars and destruction while your troops, walls, defenses, and other structures continue to improve.
BH4 Balanced Layouts
Balanced BH4 layouts combine Builder Hall protection, defensive overlap, controlled spacing, and practical coverage around the outside of the base. They are suitable for regular Builder Battles when you want a flexible design rather than a layout built around only one defensive objective.
What Makes BH4 Different from BH3?
Builder Hall 4 is not simply a larger version of BH3. As more buildings are added to the base, poor spacing and unsupported defenses become easier for attackers to exploit. Your layout must control a larger number of possible targets without leaving a clear route through the middle.
Layout Copying Becomes Available
Builder Hall 4 is the first Builder Hall level where the in-game layout copying feature is available. This makes it easier to try a new design, compare different base styles, and replace a layout that repeatedly fails against the same attack approach.
Single-Stage Defense Continues
BH4 still uses one defensive stage. Attackers can commit their complete army to this area, so every major defense should contribute to the same defensive plan. Avoid creating a weak side that allows troops to reach the center without facing meaningful resistance.
Important BH4 Layout Priorities
A useful BH4 design should not rely only on placing the Builder Hall in the center. It should also consider how attackers approach the walls, which buildings they are likely to target first, and how long they remain inside defensive range. Review the complete route through the base instead of evaluating each building separately.
Overlapping Defensive Coverage
Important defenses should support one another whenever their ranges allow it. If one defense can be attacked without another defense responding, that area may become an easy entry point. Overlapping coverage makes it more difficult for attackers to remove a key building safely.
Controlled Building Spacing
Buildings should be spaced far enough to interrupt troop movement but not so far apart that attackers receive easy destruction outside defensive range. Use moderate spacing to make troops travel, change direction, and spend more time under defensive fire.
Protected Entry Routes
Inspect every side of the layout and identify where an attacker is most likely to begin. Important routes should lead toward defensive coverage rather than directly toward the Builder Hall. Walls and nearby buildings can be used to influence which targets troops approach first.
Useful Outer Buildings
Outside buildings can increase travel time and separate attacking troops, but they should serve a clear purpose. Avoid placing too many unprotected structures together, because attackers may collect easy destruction before entering the defended part of the base.
How to Choose a BH4 Layout
Select a layout according to the problems visible in your defense log. A compact layout may be helpful when opponents move through the base too quickly, while a moderately spread layout may work better when attackers gain excessive value from grouped buildings. The right choice depends on your defensive levels, current trophy range, and the entry routes attackers use most often.
Choose a Compact Layout When
Consider a compact BH4 layout when attackers regularly destroy isolated defenses or reach the Builder Hall without remaining under fire for long. Compact designs can improve defensive support, but avoid grouping every important building into one easily accessible area.
Choose a Spread Layout When
Consider a more spread BH4 layout when attackers gain high destruction from tightly grouped buildings. A spread design can increase travel time and reduce the value of one successful entry, provided that outer structures remain covered by nearby defenses.
How to Use BH4 Copy Links
Tap an available copy link to open the selected BH4 layout directly in Clash of Clans. The layout will appear in the Layout Editor, where you can review its buildings, walls, and traps before saving it. Make sure all required structures are available and that obstacles do not prevent the layout from being activated.
After copying a layout, compare it with your own building and defense levels. You can move traps, adjust outside buildings, or modify a wall opening to respond to the attacks you face most frequently. A copied base should be treated as a starting design rather than something that can never be changed.
BH4 Layout Review Checklist
- Check every entry side: confirm that no side provides a direct, lightly defended route to the Builder Hall.
- Review defensive overlap: important defenses should receive support instead of being isolated near the edge.
- Inspect wall openings: walls should influence troop movement rather than guiding attackers directly into the most valuable area.
- Count exposed buildings: avoid giving attackers several easy targets that can be destroyed without entering defensive range.
- Look for grouped value: do not place too many important targets where they can all be reached from the same entry route.
- Check trap purpose: place traps along likely troop paths rather than scattering them randomly around unused areas.
Common BH4 Base-Building Mistakes
- Copying without reviewing: a popular layout may still need adjustments for your defensive levels and current opponents.
- Placing key defenses near the edge: exposed defenses may be removed before they provide meaningful protection.
- Using one predictable entrance: an obvious opening can allow attackers to plan their complete deployment around a single route.
- Overprotecting only the Builder Hall: attackers may still gain high destruction if the rest of the base is poorly defended.
- Spreading the base too widely: excessive spacing can create isolated targets and reduce defensive support.
- Ignoring repeated attack patterns: if several opponents enter from the same side, that section of the layout probably needs adjustment.
Tips for Builder Hall 4 Progress
- Test more than one layout: the BH4 copy feature makes it easier to compare defensive designs and replace layouts that no longer perform well.
- Protect defensive coverage: avoid losing a major defense before the attacker reaches the main part of your base.
- Break direct paths: arrange buildings and walls so troops must turn, separate, or remain exposed to defensive fire.
- Use traps with a prediction: place traps where your layout encourages troops to travel, not simply beside the Builder Hall.
- Review several defenses: one battle is not enough to judge a layout. Look for repeated weaknesses across multiple defensive results.
- Continue upgrading: strong placement improves a base, but underleveled defenses and walls can still reduce its effectiveness.
When Should You Replace Your BH4 Layout?
Do not replace your base because of one strong attack. Review several defensive results and identify whether the same weakness appears repeatedly. A layout may need to be changed when attackers consistently enter from one side, destroy the same important defense first, reach the Builder Hall through the same route, or achieve high destruction without using most of their army.
Start with small adjustments before replacing the complete design. Moving an outside building, changing a wall opening, or repositioning a trap can alter troop movement enough to improve the next defensive result. Replace the complete layout when smaller changes fail to correct the repeated weakness.
Explore the layouts on this page to choose a BH4 base layout suited to defense, trophy pushing, or regular progression. After activating a new Builder Hall 4 Clash of Clans base, review several defensive results and adjust its walls, traps, and building positions when the same attack route succeeds repeatedly.
