3D Printed Homes
in Florida

The structural shell of a single-family home can be printed in a matter of days, not weeks. The robotic system prints the full wall system in one continuous automated pass, which is the phase that replaces framing, insulation, sheathing, vapor barrier, and stucco in conventional construction. That five-trade sequence typically takes weeks in a wood-frame build. The 3DCP pass compresses it dramatically. Total project timeline from design to enclosed shell is significantly shorter than conventional multi-trade sequencing. The full project, including foundation, MEP, roofing, windows, doors, and interior finishes, follows the same schedule as any construction project for those trades. The time savings are concentrated in the structural shell phase. For the Coastal Monolithic pilot project, the first project is shovel-ready with a 90-day construction start window.

For large-format residential construction, the fastest method is large-scale robotic concrete extrusion, which is the technology Coastal Monolithic uses. The system prints the full structural wall system in a single continuous pass directly on site. There is no factory prefabrication, no panel assembly, and no multi-trade sequencing for the wall system. The robotic arm extrudes a high-strength concrete mix layer by layer, building the full wall from foundation to roof line in one automated operation. This is faster than prefabricated panel systems, which require factory production time, transportation, and on-site assembly. It is significantly faster than conventional multi-trade construction, where framing, insulation, sheathing, vapor barrier, and stucco are installed sequentially by different crews. The speed advantage is most pronounced in the structural shell phase.
