🏗️Building on land tiles in pax.world

Using the land builder tool

Getting started

Step 1: Purchase land

Use our landsale application to purchase one or more tiles of land in pax.world. Click below for further details:

Step 2: Set up Metamask

You will need to create a Metamask wallet and link it with the Ethereum account in which your pax.world land NFT is held. Visit the Metamask website for further details.

How to use the Land Builder app

As a landowner, you will be among the first to walk around in pax.world when we start to open it up ahead of the full public launch.

Right now is the time to start designing and building your first structures ready for launch. The Land Builder app provides a staging environment corresponding to the tiles you own in pax.world, on which you can build structures and then publish them to pax.world itself.


1. Click this link or copy and paste the link text into your browser: Land Builder

2. Click “Connect your wallet”. If you have the Metamask browser extension, a Metamask window should pop up to prompt you to log in, if you haven’t already logged in. For more information on using metamask, go to https://metamask.io/faqs/.

3. Enter your login credentials in the Metamask pop-up window.

4. If this is your first login, Metamask will ask you to confirm which Ethereum account to use with our site. Make sure you select the Ethereum account containing your land NFTs.

Selecting the tile to start building

If you have more than one tile, the “My tiles” drop-down menu will allow you to select the coordinates for the relevant tile. If you don’t see all of your tiles listed, check whether the ETH account address at the top of the screen matches the one in which you hold the corresponding land NFTs. A tile consists of a central area (the “tile core”) on which it is always possible to build, surrounded by a “margin” a few metres wide. If the selected tile is the only one you own (or you own more than one but not adjacent to one another), you can only build on the tile core area. The margin, and the adjacent segments of your immediate neighbours’ tiles, must remain clear. If you own two or more adjacent tiles, then you may build on or across the margin segments connecting them.

The app programmatically imposes a uniform building height limit of 8.6 metres. This is enough to build a two-storey building with a flat roof given that a standard storey in pax.world is 4 metres in height and floor/ceilings are 20cm deep. A variable height limit system is in development allowing landowners with multiple tiles to build higher, more details of which will be released in due course.

Selecting and deploying a shape

The panel on the left of the screen contains all the shapes and objects available for use. The simplest way to choose is to scroll down until you find the desired piece. Hovering your mouse pointer over an object will temporarily display its name.

The selection can be narrowed down using the Search bar or the category filter.

Type a search word (1) to find all toolbox objects with that word in their name. As soon as you begin typing, the selection will begin filtering and show only objects containing that string of characters.

Use the category filter drop-down (2) to see all objects within the selected category.

You can combine the search and category filter functions to refine your selection.

To place a shape onto the tile, use the left mouse button to click and drag the shape from the menu into the building area.

Changing the position of a shape

To manually reposition a shape horizontally, use the left mouse button to click on the hand symbol and hold the left mouse button while you drag the shape around.

Alternatively, click the white directional arrows at the base of the object.

To reposition the shape vertically, click the up or down arrows or hold the left mouse button and drag up and down.

The position of the shape can also be adjusted by entering values in the X, Y, and Z fields in the “Object settings” panel on the right of the screen.

NOTE: Moving or rotating a shape so that any part of it is lower than the ground, higher than the relevant height limit or outside of the tile boundary will result in an “out of bounds” notification and the shape will revert to the last allowed position.

Rotating a shape

The selected shape can be rotated by clicking the rotational arrows at the base of the object.

Alternatively, the shape can be rotated by entering values in the “Rotation” fields under Object settings.

While placing/moving the shape by holding the left mouse button and dragging, the mouse wheel can be used to rotate the shape.

Scaling a shape

To change the dimensions of the shape, move the “Scale” sliders X (depth), Y (height) and Z (width). Certain shapes can only be scaled uniformly, i.e. they can be resized but the proportions are fixed.


Whether manipulating an object manually or using the number fields and/or sliders in “Object settings”, any modification causing an object to be “out of bounds”, meaning either buried in the ground, exceeding a height limit, or overstepping the edge of the tile or buildable area, will return an “out of bounds” message and cancel the modification.

Managing objects (select, deselect, group, duplicate, delete)

To select a deployed object for modification, simply click on it. To deselect that object, either click on another object or click the “X” at the top right corner of “Object settings”. This will allow you to view the build without guidelines and arrows.

To select more than one object simultaneously, hold the CTRL key while clicking all the objects in turn. Objects grouped in this way my be repositioned or deleted as one, but may not be scaled as a single object.

To delete one or more selected objects, click the delete button. To duplicate a selected object, click the duplicate button. This will generate a duplicate shape over the original shape, highlighted with a blue outline. Click and drag the new object to separate the two.


Snapping two objects together allows them to be joined precisely at one of a number of contact points.

Snap points are denoted by blue dots on the outer surface of shapes.

To link two shapes together, use the left mouse button to click and drag a snap point to a snap point on the other shape. The two shapes will be snapped together at the designated point of contact.


Banners and screens may be placed to display images. The ratio of banner dimensions is fixed, meaning that they may be scaled up or down uniformly but the shape cannot be altered.

To upload an image, select the banner and click the “Upload image” button in “Object settings”.

Land Builder options

The Land Builder options pop-out allows the gridlines to be toggled on or off and to be moved up and down on the vertical axis to assist with placement of shapes. Select show/hide and move the slider for height.

The “snap” and “snap step” setting allows shapes to be moved in fixed increments.

Publishing changes

To publish all modifications to the tile (saves the modifications and, once pax.world is live, transposes all structures to the land tile in pax.world), click “Publish”.


To disconnect your wallet and leave the secure land builder environment, click “Disconnect” at the top right of the screen, to the right of the wallet address.


pax.world is still under construction and as such you may find the odd bug. If you do, no need to panic, let us know and we’ll squash it right away, as we continue to strive for excellence. To notify us simply take a screenshot or recording and send it together with a description of the problem encountered to support@pax.world. Thank you and happy building.
