Reinventing How Homes are Built
3DCP is a groundbreaking construction technology that PCI Builders is bringing to the Los Angeles area. PCI’s first 3DCP permit was approved in February 2026 for a home to be constructed in Altadena, California, a community impacted by the Eaton Fire in early 2025. The printing of the home and detached garage is expected to begin in June 2026. As communities rebuild after devastating wildfires, technologies like 3DCP offer a new approach to constructing more resilient homes.
Using a large computer-controlled robot, structural walls are printed layer by layer from a digital design using a proprietary concrete mix from Sika. This advanced process allows homes to be built with precision while creating strong, durable concrete structures. After the concrete cures, typically 7 to 28 days, roof construction begins and the remainder of the home is completed using conventional building methods, incorporating fire-resistant components such as steel roof trusses and fire-rated roofing shingles. The result is a virtually indestructible structure that combines the strength of concrete with the efficiency of next-generation construction technology.

Why 3DCP Makes Sense for Southern California
Southern California faces increasing challenges including housing shortages, rising construction costs, and growing demand for resilient building methods. Technologies like 3DCP offer an innovative way to help address these challenges. Concrete structures provide exceptional durability, while the efficiency of the printing process helps accelerate construction timelines and reduce labor demands. This combination allows builders to deliver high-quality homes while helping address the region’s urgent need for new housing.

FAQ
What is 3D concrete printing?
3D concrete printing is a construction method that uses a computer-guided robot to print a proprietary mix of concrete in layers, forming the walls of a building.
What is the process of printing a 3DCP home?
Guided by a digital design, the printer constructs both interior and exterior structural walls layer by layer. After curing for approximately 7–28 days, roof construction begins and the remainder of the home is completed.
Are 3DCP homes fire resistant?
Yes! 3DCP homes are constructed using concrete, which is a non-combustible building material and provides a high level of fire resistance compared to traditional wood-framed construction. When combined with fire-resistant roofing, windows and other building material, 3DCP homes are basically fire proof.
Do 3D printed homes look different from traditional homes?
Not necessarily. By using other Sika products, printed walls can be finished to resemble traditional stucco or other architectural finishes, maintaining the appearance and architectural quality homeowners expect from a more traditional home. However, if you are looking for something more non-traditional, 3DCP allows for greater flexibility in shapes, curves, and architectural layouts that would be difficult or costly to achieve using conventional methods.
