Most LEGO cities only need around 8–20 carefully chosen buildings to feel complete. A realistic city isn’t defined by how many buildings you own, but by how you arrange them. Roads, pavements, parks, transport, vehicles and open spaces all help create the feeling of a real place. Starting with a handful of varied buildings and expanding gradually almost always produces a better-looking city than filling every available space with expensive modulars.

Why This Question Matters

One of the biggest misconceptions among new LEGO city builders is that they need dozens of Modular Buildings before they can have an impressive layout.

In reality, the opposite is often true.

Many exhibition-quality LEGO cities feel enormous because they have:

Wide roads
Parks and green spaces
Different neighbourhoods
Sensible spacing between buildings
Trains and transport links
Interesting scenery
Plenty of life between the buildings

A city made from ten thoughtfully placed buildings can feel far more realistic than one containing thirty buildings squeezed onto the same table.

The goal isn’t to own the most buildings—it’s to create the most believable city.

What Counts as a Building?

When people talk about LEGO city buildings, they often mean the official LEGO Modular Buildings.

However, a realistic city is made up of many different building types.

These include:

Modular buildings
LEGO City buildings
Houses
Apartment blocks
Shops
Cafés and restaurants
Offices
Fire station
Police station
Hospital
School
Train station
Warehouses
Factories
Custom-built (MOC) buildings

Mixing different styles, heights and functions creates a city that looks much closer to a real town.

How Many Buildings Do You Actually Need?

5–8 Buildings: A Great First Neighbourhood

Don’t underestimate what you can achieve with just a few buildings.

A layout might include:

Two houses
One café
One small shop
One civic building such as a fire station
A small park

With proper roads, pavements, vehicles and landscaping, this already feels like a genuine neighbourhood rather than a collection of sets.

This is an excellent target for your first year of building.

8–15 Buildings: A Complete Small Town

For many LEGO fans, this is the sweet spot.

At this size you can introduce different parts of a town while still keeping the layout manageable.

Typical mix:

2–3 modular buildings
Houses
Shops
Restaurant
Fire station
Police station
Small office
Train station
Park

You’ll have enough variety to create interesting streets without feeling crowded.

15–30 Buildings: A City with Character

Around twenty buildings is where your layout starts feeling like a proper city.

Instead of thinking about individual buildings, start thinking in districts.

For example:

Residential

Houses
Apartments
Schools

Commercial

Shops
Offices
Restaurants

Civic

Fire station
Police station
Hospital
Library

Leisure

Parks
Cinema
Museum
Sports facilities

Industrial

Warehouses
Workshops
Small factories

Grouping similar buildings together immediately makes the city feel more realistic.

30–60+ Buildings: A Large LEGO City

Once your city reaches this size, planning becomes far more important than buying more buildings.

Most experienced builders spend increasing amounts of time on:

Roads
Landscaping
Railways
Lighting
Public transport
Terrain
Rivers
Bridges
Storytelling
Small details

Ironically, many spectacular LEGO cities actually have fewer buildings per square metre than beginner layouts because they include so much open space.

Why Beginners Buy Too Many Buildings

It’s tempting to think every empty baseplate should eventually hold another building.

Unfortunately, this often creates cities that feel:

Cramped
Repetitive
Unrealistic
Difficult to expand

Real towns contain far more than buildings.

They include:

Car parks
Playgrounds
Town squares
Gardens
Rivers
Woodland
Construction sites
Empty plots awaiting development

These features make a LEGO city feel alive.

[BR²] Brick Squared Tip

Whenever you’re considering buying another building, ask yourself:

Would my city look better with another building—or with a park, wider road, railway, river or public square?

The answer is often the second option.

A Better Way to Plan Your Collection

Rather than buying buildings randomly, aim for balance.

A simple guideline is:

Building Type	Suggested Share
Houses & apartments	20%
Shops & restaurants	20%
Civic buildings	20%
Modular buildings	20%
Industrial & specialist buildings	20%

This isn’t a strict rule—it simply helps prevent your city becoming one long row of modular buildings.

Buildings Aren’t the Whole Budget

Many beginners spend almost their entire LEGO budget on buildings.

A more balanced approach often produces a better city.

Consider investing across:

Buildings
Roads
Pavements
Trees
Street furniture
Vehicles
Minifigures
Lighting
Landscaping

The small details are what make visitors stop and look closer.

Before You Buy

Before purchasing another expensive building, ask yourself:

Do I actually have somewhere realistic to place it?
Does it add something my city doesn’t already have?
Will it improve the overall layout?
Could the same budget create more impact through roads, landscaping or custom buildings?

Buying slowly almost always leads to a better city.

Build in Layers

A sensible order for most beginners is:

Houses
Small shop
Civic building
Roads and pavements
Park
Modular building
Specialist buildings

This creates a believable town from the beginning instead of a street full of landmarks with nowhere for people to live.

Common Mistake

Many people buy every new Modular Building because they’re afraid of missing out.

A few years later they have a shelf full of beautiful buildings but no roads, no parks and nowhere for them to fit together.

Build the city—not just the collection.

Budget Builder

A fantastic-looking city doesn’t require dozens of expensive modulars.

Instead, mix:

Official LEGO City sets
One or two modular buildings
Custom houses built from LEGO Pick a Brick
Individual parts from BrickLink
Small MOCs built from your existing collection

One custom-built house can often cost less than a single modular building while adding far more variety.

Inspiration

Look at photographs of real towns rather than only other LEGO cities.

Notice how much space is given to:

Roads
Trees
Car parks
Parks
Public squares
Rivers
Railway lines

These are often the features that make a LEGO city feel convincing.

Required Parts and Tools

No additional parts are required for this guide, but these resources can help as your city grows:

Baseplates or MILS modules
Road plates or brick-built roads
Graph paper or digital planning software
LEGO Pick a Brick for common pieces
BrickLink for retired elements

Key Takeaways

Most LEGO cities only need 8–20 buildings to feel realistic.
Variety matters more than quantity.
Roads, parks and public spaces make cities feel larger.
Plan neighbourhoods rather than buying random buildings.
Leave room for future expansion.
Spend your budget across the whole city, not just buildings.

[BR²] Brick Squared Verdict

If you’re just starting a LEGO city, don’t chase a number.

Instead, aim to build a place that feels believable.

A handful of houses, a shop, a civic building, a park and well-planned roads will almost always create a more enjoyable city than a table packed edge-to-edge with modular buildings.

The best LEGO cities grow naturally over time. Give yourself room to expand, tell stories and enjoy the process. That’s what keeps the hobby rewarding.
