Stone
From Project Rebearth
Stone is one of the three primary resources in Project Rebearth and the primary construction material in the Stone Biome. It is extracted from quarries and processed by Stone Cranes. Unlike 
Wood, 
Stone is not consumed as daily upkeep by housing.
Production
[edit]| Building | Wood | Stone | Earth | Arctic | Workers | Notes |
|---|---|---|---|---|---|---|
| Quarry | +0.01/m² | +0.03/m² | +0.01/m² | — | -0.01/m² | Polygon building; rate scales with area |
| Stone Crane | +20 | +30 | +10 | — | 5 | Child of Quarry; requires  Tools (-0.1/day)
|
| Improved Stone Crane | +50 | +80 | +20 | — | 5 | Upgraded Stone Crane; requires Tools (-1/day)
|
| Foraging Hut | +1 | — | +2 | — | 1 | Also produces  Food, Wood/ Earth
|
The Quarry is the primary source of Stone and has the highest per-area output in the Stone Biome (+0.03/m²/day), 3 times the rate in the Wood Biome and Earth Biome (+0.01/m²/day). The Stone Crane is a child building of the Quarry that provides a flat bonus per day (+30/day in the Stone Biome) but requires Tools (-0.1/day). The Improved Stone Crane is a direct upgrade with significantly higher output (+80/day in the Stone Biome) at a higher Tools cost (-1/day). The Quarry is not available in the Arctic Biome.
Consumption
[edit] Stone is not consumed as a daily rate by any building. It is only used as a building material (construction cost).
Storage
[edit]| Building | Volume |
|---|---|
| Center | 5,000 (shared with all resources) |
| Square | 10,000 (shared with all resources) |
| Warehouse | 5,000 (shared with all resources) |
| Foraging Hut | 100 ( Food, Wood, Stone, Earth)
|
Other Sources
[edit]- Trade can be used to buy and sell Stone on the Market (1,000 capacity) or Port (5,000 capacity).
- Expeditions yield random basic resources ( Wood, Stone, Earth, or
Glass) per area explored. - Celebration events can grant bonus Stone.
Affected By
[edit]| Effect | Source | Multiplier | Type |
|---|---|---|---|
| Goods production | Dubious Working Rules | ×1.2 | Policy |
| Worker Safety | ×0.8 | Policy | |
| All production | New Town Boost | ×2 | Automatic (4 days) |
| Great Federation | ×1.1 | Alliance type | |
| Science League | ×0.8 | Alliance type |
The goods production effect specifically targets Wood, Stone, and Earth production. The all production effect affects every production building in the settlement.
Changelog
[edit]February 7, 2026
- Balance The Iron Mine has been rebalanced: maximum daily production is now 100 / 60 / 40 ( Stone / Wood / Earth biomes). Production in the Wood Biome and Earth Biome is now feasible, though the Stone Biome remains most favourable.
