3D printing is a process that creates physical objects from digital designs. In the context of homebuilding, digital blueprints are translated into a home's basic structure. This is achieved with a large 3D printer, which uses a nozzle to print the design in layers. Concrete and mortar are most commonly used as the primary printing material, but recycled plastic and waste products can also be utilised.

This technique is primarily used for walls and the property's core structure. Elements such as windows, doors, plumbing, and electrics are installed later. In many cases, 3D printing is more time and cost-efficient than traditional construction. Depending on the complexity of a design, a home can be printed in days or even hours.

Here are just some of the incredible homes that have been built using this pioneering process.
