Looking to find out how building works in Valheim?. Similarly to othersurvivalsandbox games,Valheimplaces great emphasis on the player’s ability to build towering structures, mead halls, and mansions. Having a sturdy base is more important than ever thanks to theHearth & Home updateallowing players to store giant gold piles.
Our comprehensive guide tobuilding in Valheimwill teach you about building stability, how to make stone structures, building chimneys to prevent smoke buildup, and more.

Valheim building overview: how to build a base
To build a base, you’ll need a few things. Firstly,you’ll need a Hammer. The Hammer is your tool for constructing every single placeable structure in the game. You can craft a Hammer directly from your inventory crafting menu. To use the Hammer, equip it and then right-click to bring up the build menu, where you can choose what you want to place. You can then rotate the piece in the world with the mouse wheel, and left-click to place it.

Valheim building structure: stability & integrity
How to make Stone buildings in Valheim
Wood isn’t the only building resource in Valheim. Stone is obviously a much stronger material and makes for more stable foundations and structures. So how do you make Stone buildings?
To start using Stone building parts, you’ll need to craft a Stone Cutter. The Stone Cutter requires 2 Iron Ingots to craft, so you’d best consult ourValheim Iron guideto learn where you can find Iron deposits.
Once you’ve placed a Stone Cutter, interact with it and, just like with the Workbench, you’ll find a host of new building parts added to your Hammer build menu, including all sorts of Stone structure pieces.

Valheim building decay explained
All buildings have a durability or health value, and if a wooden piece is rained on it will continue to decay down to a minimum of 50% health. You’ll know if this happens because the wooden piece will turn a slightly different and less healthy colour.
But don’t despair! The decay rate is fairly slow, andyou can repair a building partusing the Hammer tool. Another little tip is that it never rains in The Plains biome, so you can leave wooden tiles uncovered in that biome and it’ll never decay.
How to build a chimney in Valheim
Another cool thing that Valheim simulates is smoke. If you build a firepit indoors, then smoke will collect above and around it unless it has some way to escape the room. This is important, because a room filled with smoke will damage you over time as you inhale the fumes.
To prevent this from happening, you’ll need a chimney. In Valheim, “chimney” is used in the loose sense of just “a place where smoke can escape”. The simplest possible method of building a chimney is to simply delete one of your roof tiles above the firepit so the smoke can escape.
However, with no roof tile above it, your firepit is vulnerable to rain. The solution here is to place another roof tile in the opposite direction, as you can see from the image below:

This way, the rain can’t get to the firepit, but the smoke is still able to escape the room.
