The Cookhouse is the building most new chiefs build, click once, and then forget about for the next thirty Furnace levels. That's a mistake — but a forgivable one, because the building is genuinely simple. There's no production race to chase, no Fire Crystal grind, and no spender-only path. What there is, instead, is a quiet sickness mechanic that punishes inattention, an upgrade gate that makes it a checkpoint for every Furnace level early on, and a meal-tier toggle that can save or sink a city during its first storm cycle.

Quick Answer

The Cookhouse converts Meat into meals to maintain Survivor Fullness and Mood. Neglecting it leads to sickness from low food quality, which is often misdiagnosed as cold. To prevent riots and illness: always keep the Cookhouse at your Furnace level, upgrade furniture using Steel, and switch to Nutritious or Fancy Meals as soon as your Hunter's Hut creates a Meat surplus.

Overview

The Cookhouse is your second unlocked building, opening up the moment your Furnace reaches Lv 1. Its job is to convert Meat — the resource produced primarily by your Hunter's Hut — into meals that feed your population. It does not produce a stockpile-able output the way a Sawmill produces Wood; instead, it operates as a continuous "kitchen" whose throughput and meal quality together determine how full your survivors stay.

The Cookhouse touches two of the four survivor wellbeing meters directly. The first is Fullness, which is the survivor stat the building is explicitly built to raise. The second is Mood, which sags when survivors are underfed and recovers when they're well-fed — meaning a poorly-managed Cookhouse can knock a city's productivity down indirectly through the morale system, on top of any direct sickness consequences.

Unlike resource-production buildings, the Cookhouse caps at Lv 10 with no Fire Crystal tiers above that. That makes it one of the few buildings in the game with a true finish line: once it's at Lv 10 with maxed furniture, it is genuinely done and stays done forever. This shapes the entire investment logic of the building, which is covered later in this guide.

Unlock and Prerequisites

The Cookhouse unlocks the moment your Furnace hits Lv 1, which makes it the second building chiefs construct. Every subsequent Cookhouse upgrade is gated by the Furnace level — Cookhouse Lv 5 requires Furnace Lv 5, Cookhouse Lv 10 requires Furnace Lv 10, and so on. This isn't a hard ceiling so much as a practical one: by the time you're capable of upgrading the Furnace to Lv 10, you have everything you need to push the Cookhouse to its own cap.

The other prerequisite — the one that catches new chiefs off-guard — is the furniture upgrade gate. Before the Cookhouse can advance from one level to the next, the furniture pieces inside the building must be raised to the maximum allowed by the current tier. This is the same gating mechanic used by the Shelters and the Clinic. The practical effect is that a Cookhouse upgrade is rarely just a building-level cost; it's a building-level cost plus several furniture-level costs, all of which need Steel.

Steel is the binding resource here. Steel cannot be produced by any city building — it comes only from Exploration rewards, Intel missions, and packs. For F2P chiefs, this means furniture upgrades are paced by Steel income rather than by anything else, and the Cookhouse competes for Steel against the Clinic, the Shelters, and (eventually) every other inner-city building you own.

The Fullness System

Fullness is the survivor stat that the Cookhouse exists to feed. It runs on a meter, and that meter has a soft ceiling determined by the combination of three factors: your Hunter's Hut level (which determines how much Meat is available to be served), your Cookhouse level (which determines how efficiently that Meat gets distributed and how high the building's Fullness ceiling sits), and the meal tier you've selected from the Cookhouse menu.

The meter behaves a bit unintuitively. Upgrading the Cookhouse alone often produces a smaller-than-expected Fullness improvement, because the Cookhouse upgrade raises the ceiling but the meal tier setting and Meat supply determine how close to that ceiling you actually sit. This is why chiefs who pour speedups into a Cookhouse upgrade and then complain that their survivors are still hungry are usually one menu-tap away from solving the problem they think they need a higher building level to solve.

The Hunter's Hut pairing matters in the other direction too. A maxed Cookhouse running Fancy Meals against an underleveled Hunter's Hut will burn through Meat faster than the Hut can replace it, and your storage will eventually drop to zero. When that happens, the meal tier silently downgrades in effect — survivors aren't being served the meal you selected if there isn't enough Meat in storage to back it up. This is the most common reason a chief will swear Fancy Meals "don't work" while seeing their Fullness meter still drag.

The Three Meal Tiers

The Cookhouse menu offers three meal options. They sit on a clean ladder: each tier costs more Meat and provides a larger Fullness bonus than the one below it. The exact numerical multiplier between tiers is not part of the public record, but the ordering and the trade-off are well-established and consistent across every game version.

Healthy Gruel is the default. It's selected automatically when the Cookhouse is first built, and it's the cheapest option in terms of Meat consumption. Its Fullness contribution is real but modest. For a brand-new city with a single Hunter's Hut and no Meat surplus, it's the right setting — anything more aggressive will run your Meat reserve dry and produce worse outcomes than just sticking with Gruel.

Nutritious Meal is the middle option. It costs noticeably more Meat per serving and provides a larger Fullness boost. The transition point — when a chief should switch from Gruel to Nutritious — is generally when your Hunter's Hut output is comfortably outpacing your survivor population's consumption rate, and you have a small Meat reserve building in storage rather than the gauge sitting at zero.

Fancy Meal is the top option. It costs the most Meat and provides the largest Fullness boost. The community-reported wisdom is that Fancy Meals are technically less efficient on a Fullness-per-Meat basis than the lower tiers, but that the inefficiency stops mattering once your Meat surplus is large enough that you're not bottlenecked. Most established cities run Fancy Meals indefinitely from mid-game onward simply because the upside (no riots, no sickness from food quality) is more valuable than the marginal Meat savings would be.

[!TIP] The tier-switch decision is reversible at any time with no cost — the menu button on the Cookhouse interface lets you change your selection instantly. This means there's no penalty for experimenting.

Sickness and the Food Quality Trap

Survivor sickness in Whiteout Survival has three primary triggers: cold (an underpowered or off Furnace, especially at night or during a storm), poor sleeping conditions (underleveled Shelters), and low food quality. These three triggers are independent. Fixing two of them does not insulate you from the third.

This is the most common Cookhouse-related mistake new chiefs make, and it's worth dwelling on because the failure mode is not obvious. A chief can have a maxed Furnace running Max Power overnight, fully upgraded Shelters with all furniture pushed to current cap, and still see survivors falling ill during a storm if the Cookhouse is on Healthy Gruel and the Meat buffer is thin.

[!IMPORTANT] Sickness from food quality looks identical to sickness from cold or poor sleep — there's no on-screen indicator telling you which trigger fired — so chiefs typically diagnose the wrong cause and double down on Furnace heat or Shelter upgrades while the real culprit sits in the menu of the Cookhouse.

The fix, when it's a food-quality issue, is two-step. First, escalate the meal tier (Gruel → Nutritious or Nutritious → Fancy). Second, verify the Hunter's Hut is producing enough Meat to sustain the higher tier, because as covered above, a higher tier with empty Meat storage doesn't actually deliver the higher Fullness. If your Meat is at or near zero and you can't keep it filled, the long-term fix is upgrading the Hunter's Hut and (if you're past Furnace Lv 6 or so) maxing out your meat-gathering research nodes in the Research Center.

There is also a productivity-loss component to this. When survivors are unhappy enough — typically from a combination of low Fullness and other wellbeing hits — they can enter a riot state that applies a flat productivity debuff across all your gathering buildings. The qualitative point still applies: a city in a riot state is producing meaningfully less than a fed, content city, and the gap is large enough that the Meat "savings" from running Healthy Gruel are usually wiped out several times over by the lost output.

Cookhouse Upgrade Costs (Lv 1–10)

Below is the full upgrade ladder for the Cookhouse, covering build cost, construction time, and Building Power gained at each level.

[!NOTE] All construction times are base times — they do not account for state buffs, alliance technology, hero skills (such as Zinman's construction reductions), Chief House enhancements, or pet skills, all of which can compress these timers significantly in practice.

The resource columns reflect the pattern used across inner-city buildings. Levels 1 through 3 cost Wood only; Levels 4 and 5 add Coal; Levels 6 through 10 also require Iron.

Cookhouse Lv	Cost (Wood / Coal / Iron)	Construction Time	Building Power
1	35 / — / —	2s	100
2	50 / — / —	9s	190
3	240 / — / —	45s	325
4	540 / 105 / —	2m 15s	505
5	2,200 / 455 / —	4m 30s	775
6	5,700 / 1,100 / 285	9m	1,180
7	20,000 / 4,100 / 865	18m	1,765
8	37,000 / 7,500 / 1,800	27m	2,350
9	78,000 / 15,000 / 3,900	40m 30s	2,935
10	130,000 / 27,000 / 6,900	54m	3,785

Reading the Cost Curve

The cost ramp is gentle compared to other buildings. The Lv 10 Cookhouse costs roughly 130k Wood — by the time you can upgrade your Furnace to Lv 10, your storehouse capacity dwarfs that number several times over.
The time ramp is also forgiving. The longest single Cookhouse upgrade (Lv 10) is under an hour at base. With even modest construction-speed buffs, the entire Lv 1 to Lv 10 path can be cleared inside a single 8-hour speedup budget.
Total Building Power at Lv 10 is 3,785. This figure is straight building-level power and does not include the additional power gained from upgraded furniture inside the Cookhouse.

Furniture and the Upgrade Gate

Each Cookhouse contains interior furniture that upgrades alongside the building. The exact furniture roster includes pieces such as the Stove, Sideboard, Dining Table, Larder, Heater, Bin, Water Bucket, and Wash Basin. The Stove is the most commonly named piece because it's the interaction point for the meal-tier menu (the menu button is accessed by tapping the Cookhouse, then the Stove inside).

Furniture caps at Lv 20, double the building cap, and follows the standard upgrade gate: every time you want to advance the Cookhouse one tier, the furniture inside must first be raised to the level allowed by the current Cookhouse tier. The Steel cost compounds quickly.

Strategy Implications

Plan furniture upgrades against your Steel income, not against your speedup budget. The Cookhouse will sit ready to upgrade for hours or days while you wait on Steel. Don't burn speedups trying to muscle through; the gate is Steel, not time.
The Cookhouse is rarely the highest-priority Steel sink early on. The Clinic's furniture has a more direct impact on sickness recovery rate. If you have to choose between a Cookhouse furniture upgrade and a Clinic furniture upgrade and your survivors are currently falling ill, the Clinic almost always wins.

Investment Tiers

The Cookhouse has a very clean investment profile. There is no Fire Crystal tier to chase after Lv 10, and no whale-vs-F2P divergence.

Day 1 (Furnace Lv 1): Build it the moment it's available, leave it on Healthy Gruel, don't worry about it.
Early game (Furnace Lv 2–5): Keep the Cookhouse upgraded to whatever the Furnace level allows.
Mid-early game (Furnace Lv 6–8): This is where Fullness starts to matter. Consider switching the menu to Nutritious Meal once your Meat surplus is consistently positive.
Mid game (Furnace Lv 9–10): The Cookhouse should be at Lv 10 by the time you're working on Furnace Lv 10. Switch to Fancy Meal as a default.
Late game (Furnace Lv 11+, Fire Crystal era): The Cookhouse is finished. It does not unlock new tiers. The building disappears from your active task list permanently.

Decision Framework

Decision	When to Act
Upgrade Building	When your Furnace upgrade is your next major goal and the Cookhouse is below the Furnace's level.
Push Furniture	When you have Steel not needed for the Clinic/Shelter, and the Cookhouse is gating its next level.
Switch to Nutritious	When your Meat storage is consistently above zero (Hunter's Hut generating surplus).
Switch to Fancy	When your Meat surplus is large enough that being away from the game won't drain it.
Drop a Tier	Whenever your Meat storage hits zero and stays there.
Ignore Entirely	Once it's at Lv 10 with furniture maxed and the meal set to Fancy.

FAQ

Why are my survivors still sick despite a maxed Furnace?

It's likely low food quality. If your Cookhouse is running Healthy Gruel or your Meat storage is empty, your survivors' Fullness will drop, triggering sickness that looks identical to cold-based illness.

Does the Cookhouse have Fire Crystal levels?

No. The Cookhouse caps at Level 10. Once you reach this and max out your Level 20 furniture, the building is permanently finished.

Which furniture piece should I upgrade first?

The Stove is the most critical as it allows access to the meal-tier menu, but generally, all furniture must be leveled up to gate the next building upgrade. Prioritize the Clinic for Steel if you have a massive sickness outbreak.

How much Meat does Fancy Meal consume?

The exact numbers aren't public, but it consumes substantially more than Gruel. Monitor your Meat storage; if it's trending toward zero, drop back to Nutritious.

Key Takeaways

Sickness is often food-related: Don't just blame the Furnace; check your meal tier.
Steel is the real bottleneck: Furniture upgrades pace your building progress, not resources.
Max level is 10: This is one of the few buildings you can "finish" early.
Match your Furnace: Keep the Cookhouse at parity with your Furnace level to avoid wellbeing penalties as your population grows.

Known Ambiguities

The following details about the Cookhouse are not fully documented in publicly available references:

Exact Meat consumption per meal tier. Tier-switch decisions should be based on storage trends.
Exact Fullness values per meal tier. The bonus is qualitative in all official sources.
The exact riot productivity debuff. While riots reduce productivity, the specific percentage (often cited as 30%) is an estimate.
Building Power per furniture upgrade. No published table breaks out furniture-specific power gains precisely.
