PALM BEACH GARDENS, Fla. — In a quiet neighborhood outside Palm Beach Gardens, a home is taking shape in a way that looks more like a high-tech factory floor than a traditional construction site. Instead of hammers and saws, large-scale machinery and laptop-controlled nozzles are layering concrete, one line at a time, to build Bettina Kretz and her husband’s new house.
The project is led by Marco Designs 3D Concrete Printing, a New Jersey-based company founded by the Garcia family. On August 26, workers could be seen monitoring the steady flow of concrete, adjusting mixes, and checking the integrity of new layers as the walls of the home grew.
“3D printing allows us to work with precision, efficiency, and durability that traditional methods can’t always deliver,” said Maximus Garcia, who monitored the mix temperatures at the nozzle head during the build.
His brother Adam Garcia handled the laptop, ensuring the machinery and pumps operated smoothly. “Every layer needs to be exact,” Adam said. “We rely on digital controls to make sure the structure is strong and consistent.”
Meanwhile, Alex Garcia checked details such as the framework of a fireplace, carefully inspecting how the printed walls integrated with planned design features. “It’s about blending innovation with comfort,” Alex explained.
The technology behind this process uses concrete extruded through a nozzle, guided by computer models, to create walls and structural elements. Unlike conventional block-and-mortar construction, the method reduces labor costs, speeds up building time, and cuts down on construction waste.
Homeowner Bettina Kretz said she and her husband were drawn to the process both for its modern appeal and its resilience. “We wanted something unique but also strong,” she said. “Knowing this home is being printed layer by layer with reinforced concrete gives us confidence in its durability.”
Industry experts say that while 3D-printed homes are still rare in Florida, projects like this could become more common as developers explore new ways to address housing affordability and resiliency in hurricane-prone regions.
For Marco Designs, this build is also a statement about the future. “This is more than a house,” said Enrique Garcia, another family member on-site. “It’s a glimpse at how construction can evolve.”
By late summer, the home’s walls were already in place, with finishing work underway. The Garcias believe the approach could redefine housing across the U.S., particularly in areas facing skilled labor shortages.
