Storage & Stockpile Optimization Guide
Efficient storage is the circulatory system of your colony. Well-designed stockpiles reduce hauling time, prevent spoilage, and ensure resources are available where they are needed. Poor storage design forces settlers to walk 50+ tiles per trip, wastes 30% of your food to decay, and creates production bottlenecks. This guide covers stockpile priority systems, shelf vs floor storage, temperature zone management, decay mechanics, and optimal stockpile layouts for every resource type.
Stockpile Priority System
The priority system controls where items are stored and in what order they are consumed. Each stockpile can be assigned a priority level (Low, Normal, Preferred, Important, Critical). Settlers will always move items to the highest-priority stockpile that accepts them. This system is the key to creating efficient material flow through your colony.
Critical strategy: Use priority to create "pull" systems. Place a Critical-priority stockpile next to each workstation, set to accept only the inputs that workstation needs. Place a Normal-priority "bulk" stockpile in your main storage area. Result: settlers haul bulk resources to the main storage, then secondary haulers move items from bulk storage to workstation-side stockpiles. This ensures every workstation has materials within arm's reach while bulk storage remains organized.
Priority Example: Kitchen Flow
Kitchen stove has a Critical-priority 2x2 stockpile accepting only raw meat + vegetables. Cellar has a Normal-priority 6x6 stockpile accepting all food. Farmers deposit harvest in the cellar. A hauler moves food from cellar to kitchen stockpile. Cook grabs ingredients from the 2x2 stockpile at arm's reach — never walks to the cellar. Result: cooking time cut by 40%.
Shelf vs Floor Storage
Wooden shelves (crafted at a carpenter's bench) provide a critical storage density advantage. A single shelf occupies 1 tile but provides storage equivalent to 3 floor tiles. Additionally, items on shelves have a slightly reduced decay rate (approximately 10% slower spoilage) compared to items on the floor. Shelving every stockpile tile effectively triples your storage capacity per room.
| Storage Type | Capacity per Tile | Decay Modifier | Cost to Build | Best Use |
|---|---|---|---|---|
| Floor Stockpile | 1x (baseline) | 100% (normal) | Free (designate) | Bulk stone/wood, temporary overflow |
| Wooden Shelf | ~3x capacity | ~90% spoilage (slower) | ~15 wood per shelf | Food, medicine, valuable items, long-term storage |
| Weapon Rack | ~2x capacity | N/A | ~20 wood per rack | Weapons and ammunition near defensive positions |
| Armor Stand | ~2x capacity | N/A | ~20 wood per stand | Armor storage near barracks or armory |
Shelf Strategy:A 6x6 underground room with shelves provides dramatically higher effective storage capacity than floor stockpile alone. Shelves reduce spoilage rates and increase storage density. Smaller rooms are easier to temperature-control and require less excavation labor. Always shelf your underground food cellars first, then expand shelving to other storage zones as wood supply allows. Exact capacity multipliers and spoilage rates are approximate.
Temperature Zones for Storage
Different resource types have different ideal storage temperatures. Segregating storage by temperature zone rather than putting everything in one cold room significantly improves organization and reduces unnecessary hauling. Place each stockpile zone at the optimal temperature for its contents.
| Resource Type | Ideal Temperature | Recommended Location | Storage Type | Notes |
|---|---|---|---|---|
| Raw Food | ~0-5°C | -2F Cellar | Wooden Shelves | Coldest zone — extends shelf life significantly |
| Preserved Food | ~5-10°C | -1F Cellar | Wooden Shelves | Longer shelf life, can tolerate slightly warmer temps |
| Medicine & Herbs | ~5-10°C | -1F Cellar | Wooden Shelves (dedicated) | Separate from food to prevent accidental consumption |
| Raw Stone/Ore | Any temperature | -1F or Surface | Floor Stockpile | No decay, temperature irrelevant. Store near mines/workstations. |
| Wood & Building Materials | Any temperature | Surface (covered) | Floor Stockpile | No decay but deteriorates in rain. Roof the stockpile area. |
| Weapons & Armor | Any temperature | Near defensive positions | Weapon Racks / Armor Stands | Speed matters more than temperature — put near gates. |
| Silver & Valuables | Any temperature | -1F Secured Room | Wooden Shelves | Lock the door — prevents theft during raids. |
| Raw Textiles (Flax, Wool) | Any temperature | Near Tailor Station | Floor Stockpile | Proximity to workstation > storage conditions. |
Decay Mechanics & Spoilage Optimization
Decay affects all organic items (food, herbs, medicine, animal products, textiles). The decay rate is influenced by three factors: base item shelf life, temperature, and storage type (shelf vs floor). Cold temperatures (underground cellars) dramatically slow spoilage, while hot temperatures accelerate it.
Optimal cold storage (near-freezing underground temperatures) extends food shelf life by roughly 3-4x compared to surface storage. Hot storage (summer temperatures) accelerates spoilage. Shelves provide a modest spoilage reduction bonus compared to floor stockpiles.
Optimal Stockpile Layout by Resource Type
Every resource type has an optimal storage layout that minimizes settler walking distance while maximizing storage density. Follow these layouts for a well-organized, high-throughput colony.
Food Storage Hub (-2F, 8x8 room)
Central food cellar with wooden shelves on all 4 walls. Zone 1 (left wall): raw vegetables with Critical priority. Zone 2 (right wall): raw meat with Critical priority. Zone 3 (back wall): preserved foods (bread, pickles, smoked meat) with Preferred priority. Zone 4 (center floor): overflow for harvest season with Normal priority. Staircase up to kitchen directly above. This layout separates perishable from preserved, with Critical-priority cooking ingredients nearest the stairs for rapid kitchen access.
Workshop Material Cache (Surface, 4x4 per station)
For each workstation (brewery, smithy, tailor, carpenter), place a 2x2 Critical-priority stockpile on the tile immediately adjacent, accepting only that station's inputs. Brewery: barley stockpile. Smithy: iron ore/ingots stockpile. Tailor: flax/wool stockpile. Carpenter: wood stockpile. This eliminates 100% of input-hauling time for your crafters — they never leave their station.
Bulk Construction Materials (Surface, 6x6 covered zone)
Place a large covered stockpile zone centrally in your base (ground level, roofed). Accept: stone blocks, wood planks, clay bricks — all construction materials. Set priority to Normal. This is the "Home Depot" of your colony — builders grab materials from here for all projects. Stairs directly above this zone go to mining areas; stairs directly below go to the underground base. Central location minimizes walking distance to all building projects.
Defense Equipment Cache (Surface, near each gate)
Place 2-3 weapon racks and 1 armor stand within 5 tiles of each defensive gate. Set weapon racks to accept only bows/crossbows/ammunition at Critical priority. When a raid alert sounds, settlers can grab weapons instantly rather than running to a central armory. This can save 10-15 seconds per settler in combat response time — critical for defensive battles.
Medical Supplies (Near Hospital, 2x2 shelf)
Place a locked 2x2 shelf (wooden shelves in a 2x1 arrangement) immediately adjacent to hospital beds. Accept only: medicine kits, bandages, herbs. Set to Critical priority. Lock the door except for the medic — this prevents healthy settlers from consuming medicine as food. When a wounded settler arrives, the medic grabs supplies from the adjacent shelf — no running to storage mid-treatment.
FAQ
How many stockpiles should I have in total?
For a colony of 8 settlers, the optimal setup is 6-8 specialized stockpiles (food, construction materials, workshop inputs, weapons, medicine, overflow, valuables) rather than 1-2 general stockpiles. Specialization allows temperature optimization per resource type and eliminates contamination (food mixing with stone, medicine mixing with food). Each specialized stockpile saves roughly 3-5 tiles of walking distance per settler per trip compared to one central stockpile.
Should I use shelves for everything?
Shelves for: food, medicine, valuables, seeds (everything temperature-sensitive or capacity-critical). Floor stockpiles for: stone blocks, clay bricks, raw ore, wood logs (high-volume, no-decay items where shelf capacity matters less than floor space). The 15-wood cost per shelf is negligible late-game but significant early-game — prioritize shelving your food cellar first, then expand as wood supply grows.
How do I stop settlers from hauling constantly?
Excessive hauling is usually caused by poorly placed stockpiles. If settlers are hauling constantly, check: 1) Are production stations far from their input stockpiles? Move stockpiles adjacent to workstations. 2) Are there too many tiny stockpiles? Consolidate similar items. 3) Are stockpile priorities misconfigured? Use the priority system to create pull flow (bulk → local caches). 4) Do you have dedicated haulers? Assign low-skill settlers to hauling to reduce production worker hauling time (rough estimate: hauling dogs, if available, may additionally help).
