How To Replace Wood Walls With Stone in Rimworld

Replacing wooden walls with stone in Rimworld is a straightforward process in modern versions of the game. This guide will walk you through the simple steps needed to swap out your wall materials without leaving gaps in your defenses or disrupting your colony’s operations.

Accessing the Replace Function

To begin, locate the Architect menu on the bottom left of your screen. Click on it to open the Architect panel.

Once the Architect menu is open, navigate to the Structure section. This is where you’ll find all wall-related tools.

Using the Replace Tool

Within the Structure menu, locate and press the Replace button. This tool is specifically designed for replacing one material with another, such as replacing a wood wall with stone blocks.

After clicking the Replace button, you’ll need to select what material you want to replace your current walls with. You have many options available, including slate blocks, stone blocks, and other building materials.

Selecting Your Target Walls

Once you’ve chosen your replacement material, simply highlight the walls you want to replace. You can click and drag to select multiple wall sections at once, making the process quick and efficient.

When using the Replace tool, you’ll notice a visual difference compared to normal wall construction. The replacement mode displays only the material graphic rather than the complete wall block, giving you a clearer view of what’s being replaced.

How Colonists Handle Replacements

Once you’ve designated walls for replacement, your colonists will automatically begin the process. The key advantage of using the Replace tool is that colonists bring the new material to the location first, rather than demolishing the old wall and then rebuilding.

Your colonists will then seamlessly replace the old material with the new one. As they work, you’ll recover the original material—no waste in this process.

Key Benefits of the Replace Method

The Replace tool offers significant advantages over the traditional demolish-and-rebuild method. Most importantly, there is no break in your walls during the replacement process. This means:

Animals penned behind walls remain safely contained

Your colony’s defenses remain intact throughout the transition

No temporary vulnerabilities are created

Your colonists don’t actually demolish the walls—they simply replace the material in place

This makes the Replace function an excellent choice for upgrading your base’s structures without any operational disruption.

Summary

Replacing wood walls with stone in Rimworld is a simple and efficient process. By using the Replace tool found in the Architect menu under Structure, you can upgrade your colony’s walls without demolishing them first. Your colonists will bring the new materials and swap them seamlessly, keeping your base secure and your livestock contained throughout the entire process. This method is far superior to traditional demolition and reconstruction, making it the recommended approach for any wall upgrades in modern Rimworld.
