This simple guide will detail how to increase the number of building slots you have in Rise to Ruins. This guide is about ingame mechanics, not mods or cheats.
There are 3 ways to increase the number of building slots you have.
- Upgrading the village centre.
- Building ancilleries.
- Upgrading ancilleries.
The level of the village centre will also determine how many ancilleries you can build. You can build 1 ancillery for each level of the village centre, up to 15 total. The maximum building slots will be achieved when you have fully upgraded the village centre, built all 15 ancilleries, and fully upgraded all 15 ancilleries. This will result in a maximum number of building slots of 266.
The village centre starts off with 8 building slots. The first 3 upgrades will increase building slots by 4 each upgrade. The next 11 upgrades will increase building slots by 6 each upgrade. There are 14 upgrades in total, giving a maximum building slots of 86 from the village centre.
Each new ancillery will increase the building slots by 4. You can build a maximum of 15 ancilleries with a fully upgrade village centre. All 15 makeshift ancilleries will increase the building slots by 60.
Each ancillery upgrade will increase the building slots by 2. There are 4 upgrades for each ancillery. This results in a single fully upgraded ancillery increasing the building slots by 12. All 15 fully upgraded will increase building slots by 180.
I am currently unaware of any perks in the game that increase the maximum number of building slots, but they may exist. The above numbers are without perks (if they exist), and for the InDev30 version of Rise to Ruins. Below is a screenshot of a sandbox with maximum building slots:
