Valheim – Building Guide

A guild to building… well buildings.

Support Structure

Your main limiting factor on building structures on how high up and out you can build, besides resources, is the support they have. Structure is displayed when you mouse over a building part with an appropriate tool with a highlighted color. These colors indicate how structurally sound the object is, starting at blue (indicating it’s touching a solid object such as the ground) then going from green (indicating it’s structurally sound) through various shades of yellow to a solid deep red (indicating you can’t build much more before things will start braking). There are only four ways to raise the structure of your buildings:

Connect the part to the ground, or some other object in the world such as a tree or rock. This will turn it blue. If your building on the ground and you have a green object consider using the hoe to raise the ground under it till it turns blue.

Use support structures: Diagonal beams and cross beams can be placed and generally convey a small amount of structure up from lower sections in addition to the support that is already there. They don’t add much so you ether have to use them everywhere you can or only use them when you just need that exstra little bit some where to keep something from falling down.

Build to the middle: If you are building from two supported segments and you build them together the point in the middle will get support from both of them, this means often you can get a tinny bit more area than you would otherwise have where the supports come together, paticuarly if your using support structures from them.

And finally use support poles and beams. They support buildings a lot more than just walls and floors do alone and they are the main way to hold support. Each type of beam will support a different amount before it too gives away though shown bellow (these do not count the first placement of one as it is asument the first one will be placed down blue)

Poles and Beams

Note for every bit you build up that’s less you can build out.

  • Wood pole/beam (1m) – 1 wood
  • Vertical 6 placements (6m) green – 5 placements (5m) yellowish – 4 placements (4m) deep red
  • Horizontal (from blue 1m up) 4 (4m) placements green – 3 placements (3m) yellowish – 2 placements (2m) deep red
  • Wood pole/beam (2m) – 2 wood
  • Vertical 3 placements (6m) green – 2 placement (4m) yellowish – 2 placements (4m) deep red
  • Horizontal (from blue 4m up) 2 placements (4m) green – 1 placement (2m) yellowish – 1 placement (2m) deep red
  • Log pole/beam (2m) – 1 core wood
  • Vertical 4 (8m) placements green – 3 placements (6m) yellowish – 3 placements (6m) deep red
  • Horizontal (from blue 2m up) 2 (4m) placements green – 2 (4m) placements yellowish – 2 (4m) placements deep red
  • Log pole/beam (4m) – 2 core wood
  • Vertical 2 placements (8m) green – 1 paclement (4m) yellowish – 2 placements (8m) deep red
  • Horizontal ((from blue 4m up) 1 placement (4m) green – 1 placement (4m) yellowish – brakes after that unless meeting from other side then 1 red placement can be placed in the middle.
  • Wood Iron pole/Beam (2m) – 2 wood 1 iron
  • Vertical 6 placements (12m) Green – 5 placements (10m) yellowish – 12 placements (24m) deep red
  • Horizontal (from blue 2m up) 7 placements (14m) green – 5 placements (10m) yellowish – 12 placements (24) deep red

Wooden Walls, Floors and thatch roofs

These structures can only support themselves out so much on there own before collapsing if left unsupported. I made these crude charts to show you how much you can build unsupported. If your starting at Some color other than blue just go up and out from that color, and you can see it makes a big difference how much you can place.

This is a lot of information but what it boils down to is if you want to build you can’t build that big unless you have iron sport beams because everything else is too weak to support large building.

You can built a house with core wood logs suporting it every 12m with a second floor or a tall cilling, or you can build a three story building with core wood log support beams every 8m. Anything taller you will have to pull some BS.

What kinda BS you might ask?

Well You could make a support out of the ground using a hoe and trim it with a pick axe…. this will let you get a few more floors of blue support if you do it around an already built beam. However this will leave a massive stalagmites holding up your base so …. not the most attractive looking option.

The second option planting tree’s outside your base beside the suppor beams and letting them grow, the trees will then turn all the beams inside them blue….. down side is the branches inside your base and the fact you can’t repair a tree.

Best option if you want to build big though is to go with Iron supports.

Building with Stone

Building with stone is not like building with wood. Stone can only be built on top of anywhere that it would be blue, stone, or wooden iron supports…. It has a much higher durability than any other structure but it’s vertical build structure is similar to core wood logs and it’s ability to be built horizontaly is almost non existent.

The only way to place stone horizontally is to first place a stone arch or wooden iron supports and then place the stone on top of it. Using just stone arches it can only go 8m out before giving out.

If you want to have a second story of stone floors you will ether have to use a lot of pillars and arches or each stone floor will have to be touching an iron support beam.

So building with stone for aesthetics is costly, and it is generally only recommended for the first floors or outer walls to protect agenst attack. However if you are going all out and have lots of iron there is no reason not to build a castle. I would still recommend sticking to wooden floors and inner walls though as you need one iron support per 2 floors atleast if they are placed above ground level.

Stone has it’s own support:

  • Stone Pillar (2m) 5 stone
  • 3 placements (6m) green – 2 placements (4m) yellow – 2 placements (4m) deep red.

All stone can be stacked as high so you won’t get any stone over 16m stacking stone on stone.

However stone supported by wooden iron beams gets you more:

  • 6 placements (12m) green – 4 placements (8m) yellowish – 3 placements (6m) deep red.

So with wood iron support you can have 28m tall stone walls. This makes an epic castle possable, just very very costly.

My suggestion: Use stone for the outer walls of your base…. it’s not sturdy enough to build the base itself with.

If you want an epic stone build, start by building the wood iron supports first, horizontal supports add there support value to a stone wall, so you can build poles far appart and every so often add horizontal beams to support the walls so they will go higher.
