This guide explains how to use the Island Designer app to do construction on your island in the game Animal Crossing: New Horizons (ACNH) for the Nintendo Switch. Learn about the types of construction and how to get the permit to unlock this feature, and how to dig rivers, destroy cliffs, and more.

What is Terraforming and Landscaping?

We love Terraforming
Both Terraforming and Landscaping are words used for changing the cliff, river and pond layout of your island.

Unlike previous games, you can re-shape most of your island as you wish in New Horizons. You could make it entirely flat, surround everything with rivers or even recreate landscapes from other games, the possibilities are endless!

To do all of this, however, you first need to get the Island Designer App from Tom Nook.

To unlock the Island Designer app, you will need to raise your Island Star Rating to 3 Stars. As this is essentially the last mission of the main story, you'll need to complete all the requirements up to this point in order for Island Designer to become available.

Expect to spend a lot of time exploring the game and completing tasks for Tom Nook before Island Designer comes available. To learn what all you'll need to do, check out our full story guide below.

List of Permits and How to Unlock Them

Exchange for Miles at Nook Stop

After you've unlocked the Island Designer App, all the relevant permits will become available at Nook Stop. Only the basic Construction Permit is available initially. You can buy each of the permits in exchange for Miles.

List of Permits

Permit Usage How to Get
Construction PermitIsland Designer Construction Permit Building roads and pathways Unlock Island Designer
Waterscaping PermitWaterscaping Permit Creating and changing rivers, building bridges across Purchase for 6000 Miles at Nook Stop
Cliff-Construction PermitCliff-Construction Permit Creating and destroying cliffs Purchase for 6000 Miles at Nook Stop

Purchasing the Waterscaping Permit and the Cliff-Construction Permit will allow you to perform different kinds of construction across the island. As the Waterscaping Permit will allow you to build land bridges across rivers, it's recommended to buy this right away after unlocking the Island Designer app.

On the other hand, the Cliff-Construction Permit does not allow the creation of slopes, so obtaining it has a somewhat lower priority.

What You Can Do With Island Designer

Create roads in the ground

Create Roads
You'll be able to freely create roads anywhere on the ground. In the untamed wilds of the deserted island, bring in a sense of order and civilization with clear roads paving out the environment and showing how to reach essential facilities and services.

A variety of types of roads available

Types of Roads
To add a sense of variety to your town, you can use different kinds of roads for different purposes. Stone tile, brick, and even sand paths are available for your use, so you can make an island that best fits your style.

You can round the corners of paths

Round the Corners
The game has even included the detail of allowing either hard-edged or rounded-edged paths. These can be used for any purpose, including rounding out the edges of a playground as shown in the Nintendo Direct video.

Change the paths of rivers to suit your needs

Change Paths of Rivers
After you've received the Waterscaping Permit, you can use your shovel to create and change the shape of rivers. If a river is too wide, you can make it more narrow, or change it to any shape you can dream of to make your island easier to live on.

Create and destroy cliffs

Destroy Cliffs

When you've received the Cliff-Construction Permit, you can change the cliffs on your island to any shape that you like. If there's a cliff that's often in your way, you can push it back a bit or eliminate it altogether to better suit your new society.

Create waterfalls to mesh with your rivers

Create Waterfalls
When you have a river facing a cliff, you can create a waterfall at the top of the cliff to allow the river to pass through. You can combine the uses of the Cliff-Construction App and the Waterscaping App to get the best possible results.

Can I use this app on my brother’s town? I have my own switch and my own town. Can I travel to a different Island and alter their islands? With their permission of course.
