Every new Ark player has run into this frustration at least once: you’re trying to throw up a quick dino pen or a low-tier defense wall, and your second row of walls either clips weird, collapses immediately, or leaves gaps that raptors can slip through. If you’ve been fumbling with the mechanics and want to get it right first try, learning how to build 2 walls high in Ark is one of the most foundational skills you can master for both PvE and PvP play. It doesn’t take fancy engrams or rare resources, just a little understanding of how the game’s structural system works, and a few small hacks to avoid common mistakes.
Prep Steps to Follow Before You Build 2 Walls High in Ark
You don’t need high-tier gear or special permissions to pull off a clean 2 high wall build, but a little prep will keep you from wasting resources on misaligned pieces you have to tear down later. First, you need to confirm the ground you’re building on is as level as possible, because even a tiny slope will throw off the snap points for your second row of walls. You can test this by placing a single foundation piece and walking around its edges to see if there’s any visible gap between the foundation and the dirt below.
Before you start placing any walls, gather these quick supplies to make the process smoother:
- 3-4 extra foundation pieces to fix uneven gaps if your initial base layer is misaligned
- 2x the number of wall pieces you think you’ll need (spares fix snap errors fast without disrupting your flow)
- A pickaxe to demolish misaligned walls or foundations before they set and cost you half your resources
- Optional: A foundation ladder to reach the top of the first wall row if you’re playing without flyers enabled
Most players skip this prep and end up wasting 20 minutes prying misaligned walls off their foundation, so taking 60 seconds to gather these supplies first will save you a ton of headache later. It's also a good idea to turn off structure placement collision only if you're playing on a private server that allows it, but if you're on official, you'll need to work with the default snap settings to avoid errors.
Step-by-Step Placement for Perfectly Aligned 2 High Walls
The biggest mistake new players make is adding one second wall after every first wall, instead of finishing the entire first row first. I used to make this mistake all the time when I first started playing, and I’d end up with one side of my pen 2 walls high and the other side with a weird gap that dilophosaurs kept slipping through. Once your first full row is down, you can line up the second row perfectly without any unexpected shifts.
Stand on top of the first wall, or position yourself directly in front of the top edge of the first wall piece you want to add to. Hover your wall piece over the top snap point, and you'll see a faint green outline that confirms it's locked into the correct position. If the outline is red, don't force it – that usually means your foundation is slightly off level, or you're standing too far away to get a clean snap. For PvP builds, you can add a hidden fence support behind the joint between two first-row walls to boost structural integrity if you're building on a slope, but for most flat ground builds, you won't need any extra supports at all for 2 high walls.
If you're building a dino pen, make sure the gap between the top of the second wall and any overhang you add is less than 1.2 walls high, otherwise smaller dinos like microraptors or troodons can still hop over the top. You can test the height by jumping against the inside of the finished wall yourself – if you can’t hop over it, most small to medium wild dinos won’t be able to either.
Common Mistakes to Avoid With 2 High Ark Walls
First mistake is using mismatched wall types. If you use a wooden wall for the first row and a stone wall for the second, the snap points won't line up perfectly, and you'll end up with a tiny gap that's big enough for players to squeeze through in PvP. Stick to the same material for both rows unless you’re intentionally making a layered defense build, and test the snap on one section before you commit to the whole perimeter.
Another common error is building on sloped ground without adjusting your foundations first. Even a 10 degree slope can make your second row of walls snap at an angle, leaving gaps along the bottom of the second row that dinos can reach through to attack your tames inside. If you're building on a slope, use ramps or stacked foundation pieces to level out every section of your base layer before you add any walls. Foundation placement is non-negotiable for a clean build, so don’t rush this step even if you’re in a hurry to get your base up before dark.
You also don't want to place chests or crafting stations directly up against the inside of your first wall row before you add the second row. Those placed items will block the snap point for the second wall, and you'll have to move all your stuff just to finish the build. One last mistake people make for PvP bases is skipping the second row of walls entirely for lower tier builds. A 1 high wall can be hopped over by almost every medium dino, and even players can jump over them with a good running start, so 2 high walls are the minimum for any semi-permanent base.
Creative Uses for 2 High Walls in Both PvE and PvP Play
Most players only use 2 high walls for basic dino pens, but they're way more versatile than that. For PvE, you can use 2 high walls to build raised crop plot beds that keep your plants safe from roaming herbivores that would eat them if they were placed on the ground. You can also stack two sets of 2 high walls with a gap between them to create a safe path for taming aggressive dinos like Rexes or Spinos without them being able to reach you. Just leave a gap wide enough for your tranq arrows to fly through, and you can tame even the biggest dinos without risk of getting attacked.
For PvP, 2 high walls are the perfect height for shooting slits if you add a half wall between the two rows. You can shoot out at raiders, but they can't shoot back at you easily, and they can't jump over the outer wall to get into your base. They're also light enough to build quickly for raid defense if you're being attacked and need to throw up a temporary barrier to block raider access to your tames or vaults. If you're playing on a server with building destruction enabled, 2 high stone walls take twice as long to break as 1 high walls, giving you extra time to call your tribe for help if you're raided offline.
You can even use 2 high walls to create multi-level pen systems for different types of tames. Keep smaller, passive tames in the lower section inside the walls, and place larger combat tames on a raised platform behind the second wall so they can attack any raiders or wild dinos that get too close to your base. Structural integrity for 2 high walls is high enough that you can add a thin roof layer on top for extra protection from aerial attacks too, without needing extra support pillars that block your view.
At the end of the day, getting the hang of how to build 2 walls high in Ark is one of those small skills that makes every part of the game less frustrating. You'll spend less time fixing broken builds, more time exploring or taming, and your bases will be far more secure against both wild dinos and hostile players. Don't stress if you mess up your first few tries – even veteran players still occasionally misplace a wall and have to tear it down and start over. Once you get the snap mechanics down, you'll be able to throw up a 2 high wall perimeter in minutes, no matter what map you're playing on.
