Create waterfalls to mesh with your rivers

Combine the uses of the Cliff-Construction App and the Waterscaping App to get the best possible results.

When you have a river facing a cliff, create a waterfall at the top of the cliff to allow the river to pass through.

Create and Destroy Cliffs via Terraforming

When you've unlocked 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, push it back a bit or eliminate it altogether to better suit your island.

Island Designer Limits

Cannot Modify the Sandy Beach

You can't modify the beach by terraforming using the Island Designer.

It's also not possible to change the shape of estuaries and beaches, so be careful when choosing your island layout at the start of the game!

How to Choose the Best Island Layout

You cannot modify the rocks on the beach

Additionally, you can't modify the rocks on the beach with the Island Designer, so take note of that when selecting your island layout!

Cannot Move Facilities with Island Designer

Move buildings at the Construction Consultation Counter

Buildings can't be moved using the Island Designer, since it requires talking to Tom Nook at the construction consultation counter inside Resident Services.

Note that you need to have an upgraded Resident Services to use this feature.

What You Can Do at Resident Services and How to Upgrade

You cannot move the Airport and Resident Services

All facilities' locations can be moved except for the Airport and Resident Services. Select your island layout carefully when starting the game.

You Can Only (Normally) Climb Up to the Third Cliff

With the Cliff Construction Permit, you can build cliffs up to the 4th level. Normally, the 4th level can't be accessed.

However, through the help of a glitch we've discovered, you'd be able to access and place items on the 4th level. For more information, check out our guide below!

Cliff Glitch - How to Climb the 4th Level

Cannot Make Slopes

Inclines and slopes can only be constructed at the construction consultation counter inside Resident Services.

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. Buy each of the permits in exchange for Miles.

What Should You Spend Nook Miles on First?

List of Permits

Permit	How to Get and Usage
Island Designer Construction Permit	Unlock Island Designer Building roads and pathways
Waterscaping Permit	Purchase for 6000 Miles at Nook Stop Creating and changing ponds, rivers, and waterfalls
Cliff-Construction Permit	Purchase for 6000 Miles at Nook Stop Creating and destroying cliffs

Purchasing the Waterscaping Permit and the Cliff-Construction Permit allows you to perform different kinds of construction across the island.

As the Waterscaping Permit allows 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 Is Island Designer?

A NookPhone App Allowing You to Design Your Island However You Like It

The Island Designer App allows you to create roads and reshape the rivers and cliffs surrounding you.

Transform your island from a deserted wasteland ruled by nature's grip to a curated paradise with every detail tuned to your unique taste.

List of NookPhone Apps and How to Unlock Them

What is Terraforming and Landscaping?

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

Unlike previous games, you can re-shape most of your island as you wish in New Horizons.

You can 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.
