For this layout, we will need an empty box of about 73x73 tiles. So your first priority is to search for an island that holds such a large area.
You can 'measure' the amount of free space with roads. An example: if I place a road across some free space, it will show you the amount of credits spent on this road. Lets say the road has cost you 145 credits. A single piece of road costs 5 credits. This means that the road of 145 credits is actually 29 tiles long (145 / 5 = 29).
By using this technique, you can measure the amount of space you have and decide if you have enough space to build this layout.

After you have found the right spot to build your megacity, start off by building your first Eco city centre and Eco residences.

In this step you will build:
- 56 Eco worker barracks.
- 1 Eco city centre.

Required building materials:
- 117 ton building modules.
- 3 ton tools.
- 600 credits (ex. roads).

Green: residences
Yellow: city centre

The build:
Start off by building the rectangular in the centre of the layout: this should leave you a 12x16 box which will be used for the Leisure centre later on. For now, just build a City centre in this free lot and connect it with the rectangular road. After you've done that, start building the Eco worker barracks as shown on the image.

When you have finished building this layout, move to step three.

After completing step two, we move on to step three: expanding the number of residences and building some Concert halls to satisfy the need for activity for your inhabitants.

In this step you will build:
- 40 Eco worker barracks.
- 4 Concert halls.

Required building materials:
- 96 ton building modules.
- 12 ton tools.
- 2400 credits (ex. roads).

Green: residences
Yellow: city centre
Orange: concert hall

The build:
Extent your layout horizontally with a row of 20 residences on each side. After that, build 4 Concert halls on each of the four corners. Make sure you place the roads around the Concert halls precisely as shown on the image, otherwise you won't have enough room for the other buildings that we will build later on.

When you have finished building this layout, move to step four.

After completing step three, we move on to step four: building more City centers to expand the building area, building more residences and reserving space for utility buildings and futher additional buildings.

In this step you will build:
- 40 Eco worker barracks.
- 4 Eco city centers.

Required building materials:
- 100 ton building modules.
- 12 ton tools.
- 2400 credits (ex. roads).
- additional tools for upgrading your worker barracks to employee houses (1 ton tools per barracks)

Green: residences
Yellow: city centre
Orange: concert hall

The build:
Start off by building the four City centers next to the Concert halls. After adding the roads to connect them, start building the other roads and residences. This is a bit tricky, so take a very good look at the image and copy the layout precisely. The open spaces left in this layout will be filled in the next steps.

When you have finished building this layout, move to step five.

After completing step four, we move on to step five: building additional residences, Fire stations, Hospitals and Education network buildings to ensure city safety and advancement to Eco engineers.

In this step you will build:
- 46 Eco worker barracks.
- 4 Fire stations.
- 4 Hospitals.
- 4 Education network.

Required building materials:
- 188 ton building modules.
- 104 ton tools.
- 40 ton wood.
- 6400 credits (ex. roads).
- additional tools for upgrading your Eco worker barracks to Eco employee houses (1 ton tools per barracks).
- additional tools, building modules and wood for upgrading your Eco employee houses to Eco engineer apartments (2 ton tools, 2 ton building modules and 3 ton wood per house).

Green: residences
Yellow: city centre
Orange: concert hall
Blue: hospital
Red: fire station
Purple: education network

The build:
Expand the layout with more residences. When you have build those, you probably have enough inhabitants to build the Fire stations, the Hospitals and the Education networks. Once you have build the Education networks, Eco engineers will start populating your city.

When you have finished building this layout, move to step six.

After completing step five, we move on to step six: In this step we will get our city ready for the build of the Leicuse center. Besides this building, we will build the last residences, some Police stations and two Congress centers.

In this step you will build:
- 118 Eco worker barracks.
- 4 Police stations.
- 2 Congress centers.
- The Leisure center.

Required building materials (residences, Police stations and Congress centers):
- 294 ton building modules.
- 64 ton tools.
- 30 ton wood.
- 50 ton glass.
- 6400 credits (ex. roads).
- additional tools for upgrading your Eco worker barracks to Eco employee houses (1 ton tools per barracks).
- additional tools, building modules and wood for upgrading your Eco employee houses to Eco engineer apartments (2 ton tools, 2 ton building modules and 3 ton wood per house).
- additional tools, building modules, wood and glass for upgrading your Eco engineer apartments to Eco executive mansions (1 ton tools, 3 ton building modules, 3 ton wood and 4 ton glass per apartment).

Required building materials (Leisure center):
- 240 ton building modules.
- 950 ton tools.
- 184 ton wood.
- 196 ton glass.
- 50.000 credits.

Green: residences
Yellow: city centre
Orange: concert hall
Blue: hospital
Red: fire station
Purple: education network
Lime green: congress center
Brown: police station

The build:
Expand the layout with the last residences and add the Police stations. Eco executives should have moved to your city now. Once you reach 1200 Eco executives, you can start building the Leisure center: simply remove the City center and the roads in the middle of the layout and start building the Leisure center. To build the Leisure center, goods need to be transported from a Warehouse to the building site, therefore you need to build a Warehouse on the edge of the layout.

When you have finished building the Leisure center, move to the final step: step seven.

After completing step six, we move on to the final step: removing buildings which are no longer needed and adding some more residences. Now that the Leisure center has been fully build, we can remove the City centers, the Concert halls, the Congress centers and (optionally) the Education network buildings.

In this step you will build:
- 54 Eco worker barracks.

Required building materials:
- 108 ton building modules.
- additional tools for upgrading your Eco worker barracks to Eco employee houses (1 ton tools per barracks).
- additional tools, building modules and wood for upgrading your Eco employee houses to Eco engineer apartments (2 ton tools, 2 ton building modules and 3 ton wood per house).
- additional tools, building modules, wood and glass for upgrading your Eco engineer apartments to Eco executive mansions (1 ton tools, 3 ton building modules, 3 ton wood and 4 ton glass per apartment).

Green: residences
Blue: hospital
Red: fire station
Purple: education network
Brown: police station
Olive green: Leisure center

The build:
Remove the City centers, the Concert halls, the Congress centers and (optionally) the Education network buildings. After you have do that, (re)build the empty spaces with additional residences just like the image.

Congratulations! You have build your very own Eco megacity :)

By following the seven steps to build your own Eco megacity, you now have:

- A large city, built to impress friends and enemies.
- At least 354 residences for your inhabitants.
- At least 7508 inhabitants, divided into: 568 Eco workers, 1710 Eco employees, 2550 Eco engineers and 2680 Eco executives.
- Service coverage (Fire station, Hospital, Police station) over 90%.

At the end, your city will look something like this:

To build this Eco megacity, you will have to meet these requirements:

Building materials (ex. building materials for upgrades and roads):
- 1143 ton building modules.
- 1045 ton tools.
- 254 ton wood.
- 244 ton glass.
- 68200 credits.

Total maintenance costs (default settings): 1620
Total energy usage (default settings): 424
Total negative influence on ecobalance (default settings): -108

Besides these requirements, you will also need to build almost all the other buildings that will be unlocked during your game. Futhermore, patience is required aswell :P.

To keep all your inhabitants happy, you will need some production plants to produce various goods like tea, health food, communicators, etc. With a little help from a calculator, I calculated how much factories/farms you will need to keep this city running. All plants are calculated on default (=100%) productivity.

The following buildings are needed:

• 15 Fisheries
  
• 15 Tea plantations
  
• 9 Health food factories, which need:
  - 17 Farmhouses (vegetables)
  - 9 Rice farms
  
• 9 Electronics factories, which need:
  - 9 Chip factories
  - 5 Copper mines
  - 3 Sand extractors
  
• 6 Bio drinks factories, which need:
  - 6 Dairy farms
  - 11 Fruit plantations
  
• 7 Pasta dishes factories, which need:
  - 7 Farmhouses (vegetables)
  - 11 Grain farms
  - 4 Flour mills
  
• 4 Projector plants, which need:
  - 3 Diamond harvesting stations
  - 5 Rare-earth borers
  - 3 Manganese excavation robots
  
• 5 Service bots factories, which need:
  - 2 Chip factories, which need:
  • 1 Copper mine
    
  • 1 Sand extractor
  - 5 Biopolymer factories, which need:
  • 5 Aquafarms
    
  • 9 Corn farms

'Can I add even more houses to this layout?'
Yes, you can, but only when you have build your city according to the seven-step program. As you might have noticed, when selecting your Leisure center, you will see there's even more area available to build more residences (outside the outer skirts of the city). I'm guessing there can be build around 35 to 40 more residences there.

'Why haven't you removed the Education network buildings?'
Personally, I prefer to keep those buildings to broadcast the different shows to influence the inhabitants (for example: more tax incomes, more inhabitants or less consumption of goods). If you think you don't need them, just remove them and fill the empty areas with four houses.

'How do I produce all those huge amounts of goods needed for the build of this city?'
That's pretty simple: just build enough factories/farms so you always will have enough goods. When you have little space for all your buildings and therefore you are looking to build your buildings as space-efficient as possible, you might want to take a look at my other guides for all sorts of production layouts (yes, this is shameless self-promotion).

'Do you like My Little Pony?'
No, I don't.

'Those 1000+ tons of building modules and tools... you made a typo there right?'
Sorry, I didn't. You really need that much goods.

Some may know that I made a bunch of other guides for Anno 2070 as well. Check them out!
