JK3D’s 3D printed ‘Cactus Homes’ reimagine low-cost housing
Cactus Homes were part of ICON's Initiative 99 design contest
In the construction sector, 3D printing has been touted as a promising solution to building low-cost and more sustainable housing. Based on this premise, 3D printing construction specialist ICON launched Initiative 99 back in 2023, a contest that invited all manner of designers and architects to come up with 3D printed home designs that could be built for $99,000 or less. JK3D, the design studio founded by artist and 3D printing expert Julia Koerner, was awarded Honorable Mention in the contest for its Cactus Homes concept.
JK3D’s Cactus Homes are designed to be built using ICON’s construction 3D printing technology and integrate elements of nature into their design. As the project name reveals, the specific design inspiration was cacti. “The Cactus Homes takes inspiration from the natural intelligence of succulents, creating a series of homes that blend organic beauty with functionality,” JK3D elaborates. “The cactus-shaped units, each designed to reflect individuality while fostering a strong connection to nature.”
The Cactus Homes project has undergone an evolution within the context of ICON’s design competition. In the contest’s first phase, JK3D proposed a six-unit layout, which consists of varying pleated cactus-shaped structures, and a multi-function roof designed to collect rainwater and provide shade. In this configuration, the six units share a central utility wall that services all the kitchens and bathrooms for greater efficiency. In the second phase of the design contest, JK3D came up with a new layout: a two-unit duplex with enhanced efficiency and functionality. This duplex configuration also prioritizes the community aspect, while integrating features like operable skylights, storage and flexible room dividers for optimal customization.
ICON’s construction 3D printing technology (available in both its original Vulcan and new Phoenix platforms) is central to the Cactus Homes, which integrate 3D printed walls, as well as a 3D printed rainwater storage tank and various printed architectural features. The 3D printed structure of the affordable home is completed with non-printed elements, like LVL framing for the intermediate roof, insulated metal roof panels that rest on the LVL framing, roof-mounted solar panels and an operable skylight and windows.
JK3D’s Cactus Home design was selected as an Honorable Mention among a wide number of submissions from over 60 countries around the globe. ICON named six projects as winners: the three Phase I (open category) winners were Guerin Glass Architects, MTSpace Studio and ConCave; and the Phase II (open category) winners were MTSpace Studio, For Everyday Life and Beta Realities. JK3D received honorable mentions in both contest phases. Whether or not we see the Cactus Homes come to life in the future, the innovative nature-inspired designs are part of the undeniable 3D printing revolution that is taking hold in the construction industry.
