A RimWorld Mod, hosted on the Workshop
Furniture and buildings come in a quality tier (Awful..Legendary), but vanilla gives you no way to improve one after it's built — your only option is deconstructing and re-crafting from scratch.
Building Upgrades lets your construction crew rework a placed building in two ways:
- Quality upgrades — bring a building up a notch, using the exact same skill-based quality roll as building it fresh. Not a custom formula — it hooks directly into vanilla's own quality-generation feature.
- Material upgrades — rebuild a Wood building in Stone, or a Stone building in Metal, one tier at a time, never backwards. Quality is re-rolled on the swap.
A bad roll never makes things worse than they already were.
Two ways to put your crew to work:
- Select a colonist and right-click an upgradable building for a one-off "Upgrade" order.
- Flip the "Auto-upgrade" (or "Auto-upgrade material") toggle on a building and any free construction pawn will pick it up automatically.
Draw a zone that sets a minimum required quality and/or material tier for everything inside it. Buildings inside get bumped to the front of the upgrade queue over equally-eligible ones elsewhere, without force-enabling anything you haven't already switched on yourself. A zone's minimum can even push a building past your global tier cap.
Fully configurable from Mod Options:
- Have auto-upgrade (quality and/or material) switched on by default for anything new you build.
- Restrict automatic upgrading to your Home Area, any custom area, or leave it map-wide.
- Cap how far quality is allowed to climb, and separately how far material is allowed to climb.
- Tune the resource cost from 1% to 100% of the original build cost, and optionally make each successive tier cost more than the last.
- Pick exactly which stuffs are allowed for each material tier.
Freely add and remove it whenever you need to.
