How we build.
Why it works.

Coastal Monolithic delivers the structural shell. Your existing subcontractor relationships handle everything after the shell is enclosed. The model is designed to slot into a builder's existing workflow, not replace it. Coastal Monolithic mobilizes the robotic printing system, batches and delivers the concrete mix, prints the full wall system, and provides the technical documentation package. From that point, the builder's MEP, roofing, window, door, and interior finish subs take over exactly as they would on any concrete construction project. There is no proprietary subcontractor network you are required to use. The shell is the handoff point. Builders who have worked with ICF or tilt-up concrete will find the post-shell workflow familiar.

After the shell is printed and the curing verification is complete, the project transitions to standard residential construction sequencing. The finish work required is the same as any concrete or ICF home: (1) Roofing system: truss or rafter system, sheathing, underlayment, and roofing material. (2) Windows and exterior doors. (3) MEP rough-in: electrical, plumbing, and HVAC. (4) Interior partition walls: typically light-gauge steel or wood framing. (5) Drywall on interior faces of the concrete walls and partition walls. (6) Flooring, cabinetry, trim, and paint. (7) Fixture installation and final MEP connections. (8) Landscaping and site work. Final inspections and the certificate of occupancy come at the end. None of these trades are proprietary or require specialized knowledge of 3D printing. Any subcontractor experienced with concrete or ICF construction can work on a 3D printed shell. The shell is the handoff point, and everything after it is standard residential construction. The builder's existing subcontractor relationships and scheduling process apply from the shell handoff forward, and Coastal Monolithic provides the technical documentation package to support permitting and inspection throughout.

No. The interior and exterior finish trades for a 3D printed concrete home are the same trades used in any concrete construction project. Electricians, plumbers, HVAC contractors, roofers, window installers, drywall crews, and finish carpenters all work the same way they would on a conventional concrete or ICF home. The concrete shell provides the structural substrate. Conduit and plumbing rough-in are planned during the design phase and accommodated in the print. There is no proprietary system that requires specialized subcontractors. If your subs have worked on concrete construction before, they can work on a 3D printed shell.

The structural shell of a single-family home can be printed in a matter of days, not weeks. The robotic system builds the printed concrete wall system through robotic wall printing. The printed concrete wall is the proposed scope; reinforcement, grout, insulation, moisture control, coatings and finishes depend on the engineered assembly and may require separate work, so the shell phase may still require coordination with other trades. It builds the printed concrete wall system directly on site, with no factory prefabrication and no panel assembly. After printing, the concrete cures before the next phase begins, so the shell phase can be shorter than a conventional multi-trade sequence. The rest of the project, including foundation, MEP, roofing, windows, doors, and interior finishes, follows the builder's normal schedule for those trades. The Coastal Monolithic model home targets a Q1 2027 break-ground in the Englewood / Port Charlotte area, contingent on funding, site, equipment, engineering, and permits.
