Lake Flato ICON House Zero 3D printing

Construction technology outfit ICON and architecture studio Lake Flato have completed a 3D-printed, modern ranch-style home in Austin to be displayed during the SXSW festival.

ICON, the company to first sell ready-to-own 3D homes in the US, worked with San Antonio and Austin-based architecture studio Lake Flato to design House Zero.

The home is sited in a single-family residential neighbourhood in East Austin, Texas, and was built using ICON's Vulcan construction system.

The system uses 3D printing, a technology that dispenses layers of material mechanically based on a computer program, to lay the walls of the 2,000-square-foot (186-square-metre) home. The 3D-printed wall aspects took 10 days to print.

"House Zero is ground zero for the emergence of entirely new design languages and architectural vernaculars that will use robotic construction to deliver the things we need most from our housing: comfort, beauty, dignity, sustainability, attainability, and hope," said Jason Ballard, co-founder and CEO of ICON, in a release.

Reinforced by steel, the walls are printed with a proprietary material ICON calls Lavacrete – a cement-like substance that is air-tight while also providing increased insulation.

"We let the Lavacrete lead the way," Ashley Heeren, associate architect for Lake Flato, told Dezeen. "We could then use other materials in ways that were not only honest to their nature but also supported and complemented the concrete".

"While the organic nature of the 3D-printed concrete and curved walls are new design languages for us, House Zero was still entirely in line with the natural connections we seek in our architecture," said Heeren continued.

"The home expresses our shared passions for craft and performance in an inviting and comfortable family home constructed through a totally new way of building".

According to ICON, the home was built using biophilic design principles, claiming that the soft curves of the 3D-printed support walls create "naturalistic circulation routes throughout the home".

In addition to being able to build houses faster, the technology could mean that homes like this could be built at lower cost.

House Zero has three bedrooms with two and a half baths, along with a one bed and bath accessory dwelling unit. While the exterior walls are composed of the soft lines of the Lavacrete, many of the interior walls, ceiling, and rafters are made of wood.

"It’s regional and sensible and welcoming so, in that way, it’s what a really good mid-century ranch house wants to be," said Lewis McNeel, associate partner at Lake Flato. "And yet the new technology has freed it from rigid stylistic definitions and easy labels."

The living space at the front of the home is surrounded by the semi-circular Lavacrete walls punctuated by glass that provides views of the street. The flat roof is supported by rafters that run the width of the home and cantilever into awnings.

ICON does not currently have plans to sell House Zero, the company told Dezeen, but instead will use it as a place to bring "partners, architects, organisations, developers, and showcase the future of homebuilding".

The building was completed in time for the SXSW festival, which takes place in Austin from 11-20 March 2022.

In terms of sustainability, McNeel said that both the insulation properties and the cutting down of material used makes it a viable option.

"You can eliminate a number of separate materials and construction steps on a job site if you can print the equivalent of cladding, sheathing, thermal breaks, formwork for structure and interior finish all in one pass of the printer," he said.

3D-printed houses have been gaining in popularity worldwide and even beyond.

ICON has been active in this push, working with designers like Yves Behar to create a 3D-printed community in Latin America as well as with BIG and NASA to plan buildings for the moon.

3D-printed neighbourhood

Construction companies ICON and Lennar are collaborating with architecture studio BIG to create a neighbourhood of 100 3D-printed houses in Austin, Texas.

Scheduled to break ground in 2022, the scheme will be the world's largest community of 3D-printed homes when it completes, according to Texan firm ICON.

3D-printed neighbourhood of homesThe neighbourhood will include 100 3D-printed homes

Co-designed with Danish architecture studio BIG, the commuinty is set to be built on an unconfirmed site in the city. More details of the houses' floor plans and design will be announced next year.

Each home will be printed using ICON's Vulcan construction system, which uses controlled robotic machines to create layers of Lavacrete – a propriety Portland Cement-based mix made by the company.

"ICON's 3D printing technology produces resilient, energy-efficient homes faster than conventional construction methods with less waste and more design freedom," said ICON.

"Designed and engineered from the ground up for volume 3D-printing of homes with precision and speed, ICON's Vulcan construction system can deliver homes and structures up to 3,000 square feet," it continued.

According to the firm, the neighbourhood of houses will be built to the International Building Code (IBC) structural code standard.

ICON also said that it expects its Vulcan-printed homes to last "as long or longer" than those built with concrete masonry units (CMUs).

Homebuilding company Lennar will fit each neutrally-coloured house with gabled roofs that will feature photovoltaic panels.

"Our design approach modernises the aesthetic of the suburban home, while the 3D-printing technology texturises and provides distinctive touchpoints for each space," added ICON.

"The freedom of form facilitated by this building technology – including the sinuous curves of the walls – combines with traditional construction materials to create homes that are both aesthetically and physically unique."

The neighbourhood of 3D-printed homes will follow four recently completed houses in East Austin, Texas that were also constructed using Vulcan technology called the East 17th Street Residences.

Other 3D-printed housing projects around the world include an Italian dome-shaped, low-carbon house prototype made from clay and the Netherland's first lived-in 3D-printed home that resembles a grey boulder.

3D-printed home in Austin

A quartet of houses designed by local firm Logan Architecture and built from 3D-printed concrete by construction tech company ICON has completed in Austin, Texas.

The East 17th Street Residences in East Austin are now on the market, which construction company ICON and developer 3strands claim is a first. "They are the first 3D-printed homes for sale in the US and ready for move-in," ICON told Dezeen.

East 17th Street ResidencesThe East 17th Street Residences development includes four homes of varying sizes and layouts

The four dwellings have ground-floor walls built using ICON's Vulcan construction system, which uses a robotic armature to layer Portland-cement-based material Lavacrete into striated surfaces.

ICON claims that this process creates a stronger and longer-lasting building material compared to traditional techniques, and makes the homes tougher in the face of extreme weather.

"3D-printing technology provides safer, more resilient homes that are designed to withstand fire, flood, wind and other natural disasters better than conventionally built homes," said the company.

The 3D-printed elements for the development, which comprises two two-bedroom homes and two four-bedroom homes, were completed in March 2021. It took five to seven days to print each house.

Although differing in size and layout, all four of the 3D-printed homes have the same external and internal features.

Black standing-seam metal clads the timber-framed upper floors and roofs, while large porches have red cedar undersides.

The houses' interiors were designed by Austin-based Claire Zinnecker, who referenced southwestern design when creating the spaces.

"Drawing inspiration from the homes' natural structural materials, wood, metal and concrete, she chose a simplified colour palette of green, white and terracotta and fixtures that play off the natural materials," ICON said.

The open-plan spaces have a neutral palette, with wood cabinetry, woven rugs and touches of greenery.

Zinnecker also incorporated glazed saltillo tiles from her collection for local company Clay Imports into some of the homes.

Flooring downstairs is finished with a concrete overlay, while engineered wood is used upstairs. Double glazing, tankless water heaters and variable capacity AC systems are all included to help with energy efficiency.

Of the small development, the two-bedroom properties are currently under contract, but both of the four-bedroom houses are still available.

3D-printed homes are popping up all over the world, built using a variety of materials that range from bioplastic to clay, and even waste from rice production.

ICON's 3D-printing technology is also being used to build a prototype habitat for Mars, designed by architecture firm BIG in collaboration with NASA.

The company is also working with the space agency on robotic construction techniques for the Moon, and planned a community of affordable printed houses in Latin America with Fuseproject.
