Frostpunk 2 Hub Buildings Guide
Hub buildings represent the infrastructure layer that connects individual districts into a functioning city network. Unlike standard district structures that serve a single zone, hubs provide regional stockpile capacity, heat distribution, and fuel storage across multiple districts. Understanding when and where to build hubs separates cities that survive whiteouts from those that collapse when temperatures plunge.
Food Stockpile Hub
The Food Stockpile Hub aggregates food production from surrounding Food Districts into a centralized storage capacity that your city draws from during consumption cycles. It is the first hub most players encounter during the campaign prologue, where stockpiling 40,000 food units before the whiteout is the primary survival objective.
Place Food Stockpile Hubs centrally among your Food Districts to maximize collection efficiency. Each Food District on fertile soil feeds into the hub's stockpile, and the combined storage pool determines how long your city survives if food production halts during a blizzard. Build the hub early and expand Food Districts around it rather than scattering agricultural zones across the map. The prologue walkthrough provides exact timing for hub construction relative to the whiteout countdown.
Heating Hub
Heating Hubs distribute heat to districts that sit beyond the generator's effective range or that need supplemental warmth to offset remaining heat demand after adjacency bonuses. They are the key infrastructure piece for zero-heat housing strategies that combine generator adjacency, crevasse shelter, and cluster bonuses from our adjacency guide.
Each Heating Hub covers a defined radius of adjacent districts, reducing their net heat demand. In sprawling Utopia Builder cities, chains of Heating Hubs create heat corridors that let you build Housing and Food Districts far from the generator without sacrificing operational efficiency. Before placing Heating Hubs, model your expected heat demand with the Heat and District Calculator to avoid overbuilding hubs that consume materials without providing proportional benefit.
Fuel Stockpile Hub
Fuel Stockpile Hubs store coal and oil reserves extracted from Extraction Districts, creating a buffer between fuel production and generator consumption. During whiteouts when extraction slows and heat demand spikes simultaneously, fuel stockpiles determine whether your generator maintains output or sputters out.
Place Fuel Stockpile Hubs near both Extraction Districts and the generator to minimize transfer distance and ensure rapid fuel delivery during emergencies. Monitor fuel levels with the heat overlay activated by key 4 from our economy overlays guide. A healthy fuel stockpile before a whiteout should cover at least several days of peak generator consumption at your current district count.
Hub Research and Upgrades
The Hubs branch of the Idea Tree unlocks hub buildings and their upgrades. Investing research points in Hubs early pays dividends in every subsequent chapter, as stockpile capacity and heat distribution become increasingly critical with city growth. Hub upgrades increase storage limits, extend Heating Hub radius, and improve fuel transfer efficiency.
Balance Hubs research against Heating and Resources branches based on your immediate needs. Campaign prologue runs prioritize Food Stockpile Hub unlocks, while Chapter 1 and beyond shift focus toward Fuel Stockpile Hubs and Heating Hub networks as generator fuel types diversify and city sprawl increases. Consult the research guide for branch priority by chapter.
Hub Placement Strategy
Effective hub placement follows a hub-and-spoke model: each hub sits at the center of the district type it serves, with production districts radiating outward. Avoid building hubs on tile clusters that would be better used for production districts themselves. Hubs consume construction materials and heatstamps without producing resources directly, so their opportunity cost is real.
In multi-colony scenarios from Chapter 1 onward, hubs in New London operate independently from colony infrastructure. Frostland colonies require their own resource management without hub support until trail and Skyway connections are established. Read the colonies management guide for hub-equivalent strategies in remote settlements and the whiteout preparation guide for pre-blizzard hub checklist items.

Frequently Asked Questions
What is the difference between hubs and regular buildings?
Hubs serve city-wide or regional functions rather than operating within a single district. They connect to multiple districts simultaneously, providing stockpile capacity, heat distribution, or fuel storage that individual district buildings cannot offer.
When do I unlock hub buildings?
Basic hubs unlock through early Idea Tree research in the Hubs branch. Food Stockpile Hubs become available during the prologue, while Heating Hubs and Fuel Stockpile Hubs unlock as you progress through research and campaign chapters.
How many Food Stockpile Hubs do I need?
The prologue requires stockpiling 40,000 food before the whiteout, which typically demands one Food Stockpile Hub with multiple surrounding Food Districts. Later chapters benefit from additional hubs as population and consumption scale.
Do Heating Hubs replace generator heat?
Heating Hubs extend heat coverage to districts beyond generator range. They supplement rather than replace generator output, enabling zero-heat housing layouts when combined with adjacency bonuses from crevasses and generator proximity.
What does a Fuel Stockpile Hub do?
Fuel Stockpile Hubs store coal and oil reserves for generator consumption during whiteouts and cold snaps. They buffer fuel supply when Extraction Districts slow down or when generator demand spikes during temperature drops.
