ICON, a pioneer in large-scale 3D printing, recently partnered with Michael Hsu Office of Architecture and Catellus to bring a dozen homes to the Mueller community in Austin. Located three miles north of downtown, Mueller is a mixed-income, mixed-use community in the heart of the Texas capital with a mission to blend urban living with green spaces and sustainability through environmental design. The 2-story residences combine construction methods, with 3D printing on the first floor and traditional construction methodologies applied to the second level, capped by a standing seam roof. The modern design blends the striated appearance of the 3D-printed material with a smooth upper facade.Mueller is urban infill redevelopment of Robert Mueller Municipal Airport, created as a joint project between the City of Austin Financial Services Department and Catellus Development. Muellers redevelopment has been managed by Arterra on behalf of Catellus Development Corporation in partnership with the City of Austin since 2024. The 700-acre site hosts a mix of housing, parks and recreational areas, shops, restaurants and amenities. The ICON homes will be some of the last newly constructed homes in the community.The ICON homes range in size from one- to three-bedrooms layouts.

Though the three home options differ in size, plans for each include a largely open concept living space, with bedrooms set aside for privacy. The two and three bedroom options maximize their compact footprint with an attached two-car garage that expands the upper levels. Additionally, each home is equipped with a covered patio. ICON builds using robotic technology and proprietary cementitious-based material, CarbonX. The 3D-printed wall systems of an ICON home alleviate the intensity of temperature fluctuations through higher insulation levels. The walls are also water, mold, termite, and fire-resistant. When ICON built the worlds largest community of 3D-printed homes in Georgetown, Texas, with Lennar, a construction company specializing in homes, it utilized Vulcana robotic construction system. The large, transportable printer also built a trio of U.S. Army barracks at Fort Bliss.The two- and three-bedroom homes feature floor-to-ceiling windows that flood the interior with natural light.

The design aesthetic creates a textural balance between the interiors curvilinear concrete forms and its appliances. Residents can choose which wood finish they prefer for cabinetry, among other customizable components. In addition, large windows invite in an abundance of natural light, with glazing framing garden views.The homes are located along the Southwest Greenway at Mueller, a restored Texas blackland prairie incorporating native plants in partnership with the Lady Bird Johnson Wildflower Center. Located near Muellers first neighborhood along Tom Miller Street, the homes offer unobstructed and protected views of the golf course and walking trails.The 3D-printed material on the ground floor is the baseline for the interiors programmatic and aesthetic design. (Courtesy ICON)Although there is more commercial construction to be completed over the next few years, were nearing the end of newly constructed homes in Mueller, and we wanted to celebrate Muellers two decades of residential innovation with yet another advancement, said Sergio Negrete, principal and senior vice president of Arterra Development. These 3D-printed homes also help reflect the overall goals of the community, including affordability, diversity and sustainability.The project will break ground in 2025.
