The best LEGO city isn’t built by buying the biggest or newest sets—it’s built by creating a balanced layout. Before expanding, make sure you’ve covered the essentials: a solid foundation, connected roads, a good mix of buildings, vehicles, minifigures, green spaces and realistic street details.

Use this checklist as a roadmap rather than a shopping list. It will help you prioritise purchases, avoid expensive mistakes and build a LEGO city that feels like a real place rather than a collection of disconnected sets.

Why Use a LEGO City Checklist?

One of the biggest mistakes beginners make is buying whatever LEGO set looks exciting at the time.

After a few months they often end up with:

Five modular buildings but nowhere to place them
Lots of vehicles but very few roads
Empty spaces between buildings
No parks or greenery
Streets with almost no minifigures
A city that feels unfinished despite costing hundreds of pounds

A checklist helps you build evenly, ensuring every new purchase improves your city rather than simply making it larger.

Think of it like planning a real town. Roads come before traffic, public spaces are just as important as buildings, and people bring everything to life.

Required Parts & Tools

You don’t need to buy anything specifically for this checklist, but these items will make planning much easier:

Notebook or sketch pad
Pencil and ruler
Printed version of this checklist
Measuring tape for your display area
Existing LEGO inventory list (optional)

If you’re designing a larger layout, free planning software or simple graph paper can also help visualise your city before you start building.

Brick Squared Tip

Finish one neighbourhood before starting the next.

A complete street with finished pavements, trees, vehicles and minifigures almost always looks better than three half-finished districts spread across your table.

Many experienced builders deliberately work in small sections because it keeps motivation high and reduces unfinished projects.

Phase 1 – Planning

Every successful LEGO city starts long before the first brick is placed.

✓ Dedicated display space

Ask yourself:

Can the city stay assembled permanently?
Is there enough room to walk around it?
Will children or pets have easy access?
Can you comfortably reach every area?

A permanent location almost always results in a better city because you’re free to make gradual improvements rather than packing everything away after each build.

✓ Expansion plan

Most LEGO cities grow much faster than expected.

Instead of planning where your first five buildings will go, think about where your twentieth building might sit.

Leaving one or two edges open for future expansion can save hours of rebuilding later.

✓ Storage solution

Not every brick belongs in the city.

Plan storage for:

spare parts
seasonal displays
unused minifigures
replacement pieces
future projects

Good storage makes maintenance much easier.

✓ Budget

Decide how much you’re comfortable spending each month.

A consistent monthly budget usually produces a better city than occasional large spending sprees because you have time to plan each purchase.

Phase 2 – Foundations

The foundations determine how easy your city will be to modify in the future.

✓ Choose your building system

You have three main options:

Standard baseplates
MILS modules
A hybrid approach

Standard baseplates are cheaper and quicker to start with.

MILS (Modular Integrated Landscaping System) offers greater strength, easier transport and better compatibility for larger layouts, although it costs more in bricks.

If you’re unsure, read:

✓ Stable display surface

A wobbling table becomes more frustrating as your city grows.

Choose furniture that can comfortably support the weight of hundreds of LEGO sets and allow access from multiple sides where possible.

✓ Modular layout

Even if you don’t build using MILS, divide your city into removable sections.

This makes cleaning, moving and redesigning much easier.

Common Mistake

Many beginners buy several expensive modular buildings before deciding how the roads will connect.

Planning your road network first often produces a much more natural-looking city and prevents awkward gaps later.

Phase 3 – Roads

Roads are the framework that ties everything together.

Aim to include:

□ Straight roads
□ Corners
□ T-junctions
□ Crossroads
□ Pavements
□ Crosswalks
□ Parking spaces
□ Service roads or alleys

Well-designed roads make even a small city feel organised and believable.

Phase 4 – Buildings

Rather than collecting similar buildings, focus on variety.

Residential

Houses
Apartments
Townhouses

Commercial

Shops
Cafés
Restaurants
Supermarkets
Offices

Civic

Police station
Fire station
Hospital
School
Town hall

Leisure

Parks
Museums
Cinemas
Sports facilities

Industrial

Warehouses
Workshops
Construction sites

A city with fifteen different building types usually feels far more realistic than one with thirty similar-looking buildings.

Phase 5 – Transport

Vehicles create movement and make roads feel purposeful.

Aim for a mix of:

Cars
Vans
Buses
Emergency vehicles
Lorries
Construction vehicles
Motorbikes
Bicycles

Don’t forget parked vehicles, delivery vans and maintenance trucks. Everyday traffic adds just as much realism as emergency vehicles.

Phase 6 – People

People transform a display into a living city.

Include a mixture of:

Families
Office workers
Builders
Police officers
Firefighters
Medical staff
Tourists
Children
Cyclists
Dog walkers
Delivery drivers

Instead of placing minifigures randomly, create small stories. A queue outside a café or a child feeding ducks in a park makes your city feel alive.

Inspiration

The easiest way to spot missing details is to view your city from minifigure height.

Imagine walking through it.

Would you find somewhere to shop, eat, relax, catch a bus or meet friends?

If the answer is yes, you’re creating more than a display—you’re building a believable town.

Phase 7 – Nature

Greenery is one of the highest-impact improvements you can make.

Include:

Trees
Bushes
Flower beds
Grass
Small gardens
Parks
Woodland areas

Many beginners underestimate how much greenery softens a city and makes photographs look more realistic.

Budget Builder

Trees, flowers and landscaping often provide one of the best improvements per pound spent.

Instead of buying complete sets just for a few plants, consider sourcing leaves, trunks and foliage through LEGO Pick a Brick or BrickLink. You can often build several custom trees for the price of a single retail set.

Phase 8 – Street Details

Street furniture fills the empty spaces between buildings.

Checklist:

Benches
Street lights
Traffic lights
Bus stops
Mailboxes
Litter bins
Bike racks
Newspaper stands
Road signs
Fire hydrants

These small details are often what make visitors pause and look closer.

Phase 9 – Storytelling

Every memorable LEGO city tells stories.

Ask yourself:

What is happening on every street?

Ideas include:

A builder repairing a pavement
A café serving customers
A child chasing a pigeon
A delivery driver unloading parcels
Roadworks causing traffic
A market in the town square
Street musicians entertaining visitors

These scenes encourage people to explore your city rather than simply look at it.

Phase 10 – Future Expansion

Only once the essentials are complete should you move on to larger projects.

Possible additions include:

Railway network
Tram system
Waterfront
Airport
Industrial docks
Mountains
Lighting
Custom skyscrapers
Elevated roads
Monorails
Motorised features

These additions have far greater impact when they complement an already complete city.

Before You Buy

Before purchasing your next LEGO set, ask yourself:

Does this fill a genuine gap in my city?
Will it improve the balance of my layout rather than add clutter?
Do I have space to display it properly?
Will it connect naturally with my existing roads and buildings?
Would spending the same money on roads, landscaping or accessories improve my city more?

If you answer “no” to most of these questions, it’s probably worth waiting.

Often the biggest improvement comes from finishing your existing layout rather than adding another large set.

Commercial Recommendations

Only buy products that solve a specific problem.

Useful purchases include:

LEGO Pick a Brick – ideal for roads, pavements, trees, landscaping and replacement parts.
BrickLink – excellent for discontinued elements, rare colours and individual pieces.
Storage drawers and organiser boxes – essential once your loose brick collection begins to grow.
LED lighting kits – worth considering only after your city layout is largely complete.
Books on LEGO city building – useful for inspiration if you’re planning custom builds, but not essential for beginners.

Key Takeaways

Plan your city before buying more sets.
Build balanced neighbourhoods instead of isolated displays.
Roads, greenery and minifigures are just as important as buildings.
Tell stories through small everyday scenes.
Leave room for future expansion.
Spend money where it has the greatest visual impact, not necessarily on the biggest sets.
Review this checklist every few months as your city grows.

[BR²] Brick Squared Verdict

The biggest difference between an average LEGO city and an outstanding one isn’t the budget—it’s the planning.

This checklist isn’t about ticking every box immediately. It’s about helping you make smarter decisions with every purchase, ensuring each addition makes your city feel more complete.

If you gradually work through these sections, you’ll avoid many of the common mistakes that lead to overcrowded layouts, wasted money and major redesigns. Whether your city fills a single shelf or an entire room, this checklist will keep your build focused, balanced and enjoyable.
