The user interface is a cross between a construction document and a product detail page. Users can customize their slab based on environment, weather, water / cement ratio, product size, and product type. Each slab is cast based on user inputs and added to the communal sidewalk in realtime through a custom API.

Dimensions of the communal sidewalk are optimized for a mobile experience. Users have the ability to view the sidewalk at an angle or straight on. As slabs pass through the viewport, the HUD updates with the slabs details to inform the user how and where each slab was created.

The navigation bar dynamically adjusts to the user's state, and houses multiple functionalities within its low-profile.
