Cities: Skylines II Builds Guide#

Cities: Skylines II gives you unprecedented freedom to shape a city. From pragmatic grids to showcase towns, here are the design philosophies and techniques behind great layouts. Methodology first: this game has no copy-paste “standard numbers” for layouts — pace your expansion by the residential, commercial, industrial, and office demand bars at the bottom of the screen, diagnose problems with the various info views, and manage through development points granted by milestones, policies, and service buildings. Mastering that “signal — diagnosis — adjustment” loop beats memorizing any numbers table.

Planning Basics#

Planning Principle	Description	Level
Grid planning	The most classic and efficient but least attractive — ideal for beginners	Basic
Organic layout	Extends naturally along the terrain — curving roads — a more lifelike feel	Intermediate
Radial planning	Radiates outward from a downtown core — suits large metropolises	Intermediate
Modular design	Splits the city into independent functional modules — easy to manage and expand	Advanced

Grid Layout Guide#

Grids set the basic rhythm of zoning in this game: lots generate automatically along roads, and block length directly determines intersection density and land-use patterns. There is no standard answer for block size — the yardstick is the balance between traffic efficiency and land use:

Grid Type	Characteristics	Advantages	Drawbacks
Small blocks	Short block edges — dense intersections	Easy pedestrian crossings — traffic spreads across multiple intersections	Many turning conflicts — intersections easily become congestion points
Medium blocks	Moderate size — a mix of long and short edges	Balances traffic efficiency with land subdivision — the most versatile choice	Proportions need adjusting per functional area
Large blocks	Long block edges — intact interiors	Efficient land use — suits industrial yards and office parks	Poor internal accessibility — pedestrians and transit struggle to penetrate

Recommended layout criteria:

Set arterial directions first, let secondary roads divert traffic level by level, and bring local streets in last
Size block edges so pedestrians are willing to walk the full block, buses can loop through, and trucks can get in — no need to hard-code exact figures
After laying out each area, open the coverage info views to check for blind spots; let view feedback decide grid density

Zoning Plan#

There is no universal zoning ratio: the four demand bars at the bottom of the screen — residential, commercial, industrial, and office — reflect market gaps in real time, so build whichever type’s bar is rising. Persistently sluggish office demand usually means citizens’ education levels have not caught up yet, not that the location is bad.

Zone	Demand Signal	Ideal Location
Residential zones	Residential demand bar rising — expand in step with education coverage	Away from industry — near parks and schools
Commercial zones	Commercial demand usually follows residential growth	Between residential and office zones — along arterials
Office zones	Expand once the share of highly educated citizens rises	Near commercial zones and transit hubs
Industrial zones	Industrial demand bar rising — also confirm freight route headroom	City edge — direct rail and highway access — downwind
Public services	Add when info views show coverage gaps	Distributed evenly across districts
Parks and greenery	No dedicated demand bar — watch land value and happiness feedback	Residential centers — riversides — shorelines

Citizen education comes in three tiers — elementary, high school, and university — and that mix determines which job tiers they can fill, which in turn decides whether commerce and office industry can upgrade and expand. When demand bars refuse to rise, missing education coverage is often the link that is holding things back.

Road Hierarchy Design#

Tier	Road Type	Characteristics	Best Use
T1 Highways	Highway	Highest network speeds — does not directly serve adjacent lots	Intercity connections — regional express corridors
T2 Arterials	Multi-lane arterial roads	Highest capacity among city roads — carry cross-district traffic	Connecting major functional areas
T3 Collector roads	Medium-width roads	Bridge the hierarchy — divert load from arterials	Main routes within a district
T4 Local streets	Two-lane small roads	Lowest capacity and speed — direct lot access	Interior residential streets

Road construction and maintenance costs scale with length; the official Wiki’s road pages list unit prices for every road type in ₡/km: two-lane road maintenance runs about ₡487/km/month as a baseline, every extra lane costs more, and interchanges and highways far exceed ordinary roads. Always defer to the in-game placement cost tooltip and the Wiki’s current version. For planning, follow “dense local grid, lean arterials” — reserve expensive wide roads for genuine traffic corridors so maintenance doesn’t eat the budget once the network spreads out.

Transit Hub Design#

Highway Interchanges#

Interchange Type	Footprint	Traffic Flow	Recommended Scenario
Cloverleaf	Large	High	Highway × highway junctions
Diamond	Small	Medium	Highway × arterial exits
Roundabout	Medium	Medium	Arterial junctions
Turbo roundabout	Large	Very high	High-traffic areas

Public Transit Network#

Mode	Capacity	Cost	Best Use
Buses	Low	Low	Early game — low-density areas
Trams	Medium	Medium	Medium-density corridors — surface routes
Metro	High	High	High density — cross-district backbone lines
Trains	Very high	Very high	Intercity connections — freight
Air and water routes	High	High	External connections — tourism and logistics gateways

Network planning criteria:

Size stop spacing around walking access — spacing that is too wide leaves passengers unable to reach stops, while too-tight spacing slows the whole line’s turnaround; add or remove stops based on the passenger-flow info view
Layer backbone and feeder services: rail forms the backbone lines while buses drop down to branches and feeders
Use large hub stations to combine metro + bus + rail transfers
Reroute lines with persistently light ridership promptly — don’t let them burn maintenance money for nothing

Aesthetic Building Tips#

Tip	Description
Terrain following	Don’t flatten all terrain — use hillsides for terraced housing
Curved roads	Straight grids are efficient but look less natural than curved roads
Interleaved greenery	Tuck small parks between residential blocks — don’t concentrate only on big parks
Waterfront use	Build pedestrian zones + parks + cafés along seafronts/lakesides — raises land value and happiness
Height transitions	Transition gradually from low to high density — don’t put cottages right beneath towers
Themed districts	Use the district tool to give different areas their own themes — a unified look
Night scenery	Place streetlights and building lighting thoughtfully — night screenshots are the truest test of aesthetics

Classic Mod Recommendations#

Mod	Function	Why It’s Recommended
Move It	Precisely move any object — roads/buildings/trees	A building essential — fixes alignment issues
Find It	Search any building/tree/decoration	Quickly find the asset you want
Procedural Objects	Scale and rotate any object — total freedom	The ultimate tool for advanced builders
Node Controller	Precisely control road node positions and shapes	Craft smooth curved roads
Network Multitool	Batch-edit road networks	Quickly revise large road layouts

Architectural Style References#

City Style	Characteristics	Recommended Maps
Classical European	Radial layout — central plazas — narrow streets — protected old towns	European maps
American grid	Square grids — wide roads — CBD — suburban sprawl	Temperate maps
Dense Asian	High-rise housing — mixed use — narrow sidewalks — transit-dominated	Tropical maps
Nordic sustainable	Green energy — bike lanes — extensive greenery — low-density dispersal	Cold-climate maps

Common Building Mistakes#

Mistake	Consequence	Solution
Industry placed upwind	Pollution across the whole city	Put industry downwind / at the city edge
No road redundancy	One blocked road chokes the city	Design several parallel routes
High density too early	Traffic collapse — under-served services	Upgrade density only after infrastructure matures
Ignoring pedestrians and bikes	Unnecessary short car trips	Build pedestrian paths and bike lanes
Sprawling everything at once	Infrastructure costs spike	Develop piece by piece — finish one area before extending

Advanced Traffic Management#

Facility	Effect	How to Unlock	Best Use Case
Roundabouts	Reduce intersection conflicts — raise throughput	Assemble with the curve tool	Major arterial junctions
One-way streets	Optimize flow in a specific direction	Basic road tool	Industrial zone exits
Overpasses	Grade separation — no interference with ground traffic	Unlocked with milestone development points	Highway segments through the city
Underpasses	Underground mode — saves surface space	Unlocked with milestone development points	Downtown core areas
Bus lanes	Buses get priority — improves transit efficiency	Road types with dedicated lanes unlock with milestones	Arterials with dense bus routes
Traffic policies	Adjust travel costs and preferences — complement transit-based diversion	Policy panel unlocks progressively with milestones	Fine-tuning travel patterns citywide or per district

Layout Examples#

Grid Layout#

Advantages	Drawbacks	Best Use
Lowest road construction cost	Traffic flow is overly regular	Industrial zones
Highest land utilization	The city lacks liveliness	High-density residential
Easiest to expand	Heavy load on arterials	Early-game cities

Organic Layout#

Advantages	Drawbacks	Best Use
Natural and attractive	Less efficient road network	Low-density residential
Dispersed traffic	Hard to cover with public services	Mountain cities
Walkable	Expansion planning is complex	European style

City Service Building Advice#

Don’t size service buildings off a population ratio: open the matching info view, check coverage circles and problem markers, and add facilities or nudge locations wherever blind spots appear or buildings start getting abandoned.

Service	Demand Signal	Placement Tips
Fire stations	Burning buildings or fire-risk alerts appear	Near industrial zones and arterials
Police stations	Hot spots on the crime-rate info view	Cover commercial areas and residential access routes
Hospitals	More sick citizens — slower ambulance response	Accessible locations so ambulances can dispatch fast
Schools	Gaps in education coverage — citizens’ education stalls	Residential centers — layer elementary, high school, and university in relay
Garbage processing	Garbage starts piling up — processing capacity warnings	Away from housing — near industry
Wastewater treatment	Water pollution alarms	Downstream on rivers — away from water intakes

City Type Planning#

City Type	Core Industry	Layout Traits	Traffic Strategy
Industrial	Manufacturing + mining	Industry concentrated downwind	Rail + highway freight
Commercial	Retail + tourism	Commercial strips along arterials	Transit-first — pedestrian friendly
Residential	Services + education	Community-style layout — plenty of parks	Restrict car traffic — encourage walking and cycling
Tech	IT + R&D	Tech parks near universities	Highway network + commuter optimization

Building Expansion and DLC#

Expansions and creator packs keep adding new buildings, services, and zoning options — the available asset library grows with each release. This page does not maintain a specific building-count list — defer to the in-game unlock panel and the official store pages; for how version-level changes affect layout principles, see our update log.

Building Synergies and Combos#

Buildings of different types create synergy effects, and sensible pairing can significantly boost the city’s overall efficiency.

Education and Research Combo#

Cluster universities, research institutes, and libraries in one area to form an education campus. Universities raise nearby citizens’ education levels, research institutes build talent pipelines for high-density office districts, and libraries boost the area’s cultural appeal. The campus’s spillover effect significantly lifts surrounding land value.

Healthcare Combo#

General hospitals, urgent care centers, and rehabilitation centers form a complete medical network. Hospitals should sit near transit hubs so ambulances respond quickly; urgent care centers in densely populated areas shorten response times; rehabilitation centers can sit next to eldercare districts. Keep reasonable spacing between medical facilities to avoid overlapping coverage that wastes resources.

Transit Hub Combo#

An integrated design of metro stations, bus terminals, and train stations greatly improves transfer efficiency. Plan high-density residential and commercial around hubs to exploit the passenger-flow advantage. Large hubs also raise surrounding land value, making them good candidates for secondary city centers.

Culture and Entertainment Combo#

Clustering concert halls, theaters, and stadiums forms a cultural district that draws citizens’ leisure spending and lifts the city’s image. Cultural districts usually pair with upscale housing and boutique retail, forming a high-value calling card for the city.

Special Economic Zone Combo#

Concentrate commercial, office, and financial districts with solid transport and municipal services to form a central business district (CBD). The CBD is the city’s core source of tax revenue — prioritize its power, water, and transport supply.

Building Maintenance and Upgrades#

Buildings are not set-and-forget. As the city grows, infrastructure buildings need periodic upgrades to match rising demand:

Building Type	Upgrade Content	Upgrade Condition
Roads	Widen lanes, add interchanges	Traffic volume reaches the threshold
Schools	Increase student capacity	Population growth, rising education demand
Hospitals	Add beds	District population growth
Fire stations	Expand coverage	Rising fire risk
Power plants	Boost generation capacity	Growing electricity load

Before upgrading, evaluate current and future demand curves to avoid over-investing and wasting the budget.
