Introduction

Every district in Build and Conquer is a building decision. Housing feeds population, commerce feeds income, industry feeds the war machine, and civil defense decides whether any of it survives a raid. The building catalog spans residential blocks (mid-rise apartments and suburbs), commercial anchors (supermarkets and malls), industrial producers (factories and power plants), utilities (water networks) and military infrastructure (military bases, bunkers, air raid sirens). Placement matters as much as selection: compact residential grids share water and power coverage efficiently, industrial zones push pollution and blast risk away from housing, and every structure needs road access or it sits idle. This page breaks down what each building family does, which ones carry a nation through the V0.1 beta, and how to sequence construction so the treasury never stalls between growth phases.

Key Buildings Deep Dive

Mid-rise Apartment

Population engine of every nation

NumbersCommunity reports put a mid-rise apartment at roughly 32 population, climbing to about 48 when upgraded. That density makes it the most capital-efficient housing in the V0.1 catalog — spam it on a compact grid.

PlacementCluster apartments inside shared water network and power coverage. Every block outside utility range contributes nothing while still occupying land and road capacity.

Upgrade TimingUpgrading beats sprawling once land gets tight: +16 population per existing block is cheaper than building new blocks with new utility runs. Upgrade when the treasury has a clear margin.

Mall

Highest-value commercial anchor

Income RoleMalls sit at the top of the income hierarchy in community rankings. They bankroll interceptor networks, missile production and city upgrades — nothing else compounds your economy as hard once population supports the staffing.

StaffingCommercial buildings need workers. Population density from apartments is a mall prerequisite, not a separate project — build housing first or watch the mall underperform.

DefenseMalls are priority missile targets. Wrap the commercial district in air defense coverage; losing a mall to a strike costs more treasury than a full interceptor layer.

Supermarket

Workhorse income for the mid-game

Income RoleSupermarkets are the standard reliable earner from the first commercial districts through the mid-game. Lower ceiling than malls, but available earlier and cheaper to staff — they carry the treasury until malls unlock.

Layout TipLine supermarkets along residential fringes so workers reach them without long roads. Short commutes mean consistent output; distant shops idle.

TransitionDo not delete supermarkets when malls arrive. Mixed commercial districts diversify strike risk — if one building type is targeted, the other keeps funding the war.

Factory

Steel, vehicles and the war machine

ProductionFactories convert industrial capacity into steel and eventually vehicles. They are the bridge between raw resource gathering and a military that can field tanks and drones instead of rifle squads.

DependenciesFactories consume power aggressively and feed on iron. Scale the grid before scaling the factory floor — blackouts halt production and idle factories still cost money.

ZoningPush industrial zones away from residential cores. Separation limits blast exposure during raids and keeps housing, workers and services in one contiguous utility-covered block.

Nuclear Power Plant

Late-tier energy for heavy industry

Energy RoleThe nuclear power plant is the late-game answer to grid strain: heavy industry, missile production and growing commercial districts eventually outpace basic power plants. Reserve land for it from the start.

TimingBuilding it early wastes capital; building it late causes blackouts that freeze steel and vehicle output. Watch grid headroom and commission it when basic plants approach saturation.

RiskHigh-value, high-visibility target. A nuclear plant inside enemy missile range without interceptors is a liability — pair the build with dedicated air defense.

Bunker & Air Raid Siren

Civil defense insurance

SirenAir raid sirens warn and soften the impact of incoming attacks on your population. Cheap relative to rebuilding residential districts, they belong online before the first enemy missile launches.

BunkerBunkers shelter citizens during strikes, reducing the population losses that would otherwise undo hours of apartment growth. Place them inside dense housing clusters.

StackingSirens and bunkers complement interceptors rather than replacing them. Defense in depth — shoot down what you can, absorb what you cannot.

Core Mechanics

Buildings in Build and Conquer interlock through four resources: population, workers, power and money. Residential structures generate population; population staffs commercial and industrial buildings and expands the tax base; commercial buildings convert staffing into treasury; industrial buildings convert power and raw materials into steel and vehicles; power plants keep every other category running. Civil defense structures protect the population layer itself, because rebuilding housing after a strike is the most expensive recovery loop in the game. Construction also competes for land and road capacity, which is why grid discipline — roads planned before buildings, utility coverage stretched in straight runs — is a mechanical advantage, not just aesthetics. City level gates add a final layer: several advanced structures stay locked until population thresholds and level upgrades open them, tying the building catalog directly to the progression tree.

Advantages

A well-planned building layout compounds. Compact apartment clusters maximize population per unit of water and power coverage; commercial anchors placed against those clusters staff instantly; industrial zones sit far enough away to be targeted without taking the housing core with them. The V0.1 catalog also rewards specialization: mid-rise apartments are efficient enough to carry population alone, malls and supermarkets split income across two risk profiles, and factories open the vehicle line that raw economy never could. Civil defense structures cost a fraction of what they protect — a siren-and-bunker pair inside a housing block routinely saves more population than another apartment would have added. Players who treat buildings as an interlocked system rather than a shopping list reach city levels faster and lose less to the first raid.

Challenges

The building system punishes improvisation hard. Retrofitting utilities through a finished district is expensive, idle buildings still drain maintenance, and misplaced industrial zones drag blast risk into housing. Several key numbers — apartment population values in particular — come from community reports rather than official datamining, and beta patches have already shifted resource acquisition in ways that ripple through factory planning. Land is also finite relative to ambition: late-game nations need space for nuclear power, military bases and interceptor layers, and districts built without expansion corridors force painful relocations. Finally, every high-value building is a missile target. The stronger your economic core, the more you need air defense — buildings alone cannot defend the treasury that built them.

Frequently Asked Questions

Which building should I place first?+

Mid-rise apartments, immediately wrapped in road, water and power coverage. Population gates every other system — workers, taxes, city levels — so housing is never wasted spending. Add a supermarket as soon as population exists to stabilize the treasury, then expand outward along the grid you planned. Every other building type you will ever place depends on the citizens these first blocks produce.

How many apartments do I need for city level 2?+

You need 250 population total. At roughly 32 population per mid-rise apartment (about 48 upgraded), that is around 8–10 base apartments or roughly 5–6 upgraded ones, plus any population from other housing. Utility coverage is the real constraint — uncovered blocks produce zero. Count only powered, watered residents when you estimate your progress toward the gate.

Should I cluster building types or mix them?+

Cluster by function. Residential blocks share water and power efficiently, commercial strips staff from adjacent housing, and industrial zones stay separated from the core to limit blast damage. Mixing everything looks organic but fragments utility coverage and concentrates risk. Three clean zones — housing, commerce, industry — with straight utility runs between them outperform any scattered layout over a full play session.

When do I need a nuclear power plant?+

When basic power plants can no longer keep factories, commercial districts and services running without brownouts. For most nations that is deep mid-game, once vehicle production is online. Reserve the land early so you are not relocating districts later; commission the plant the moment grid headroom gets thin, because one blackout during steel production costs more than the plant itself.

Quick Tips

💡

Plan roads before buildings, every time. A grid laid down first lets every later structure snap into utility coverage; retrofitting roads through finished districts wastes land, money and patience. Ten minutes of planning saves an hour of rework — sketch blocks, run water and power along the same lines, and leave expansion corridors for the level-5 infrastructure you will need later.

💡

Keep housing, commerce and industry in separate contiguous zones, each with dedicated utility runs. Residential clusters maximize population density, commercial strips staff instantly, and industrial zones stay far enough from housing that a raid on the factory does not wipe your citizens. The separation also keeps blast risk, pollution and missile targets away from the population that funds everything.

💡

Treat every high-value building as a future missile target. Malls, factories, military bases and nuclear plants deserve air defense coverage the day they open. The cost of one interceptor layer is almost always less than rebuilding the structure it protects — and unlike units, lost buildings take construction time you can never get back mid-war.
