Houston is putting itself front-and-center to help make sustainable, affordable housing a reality for 80 homeowners in an innovative scalable housing community. Developer Cole Klein Builders has partnered with HiveASMBLD to pioneer what’s touted as the world’s first large-scale, one-of-a-kind, affordable housing development using 3D printing technology — merging robotics, design, and sustainability.

Located across from Sterling Aviation High School, near Hobby Airport, Zuri Gardens will offer 80 two-bedroom, two-bathroom homes of approximately 1,360 square feet, situated in a park-like setting that includes walking trails and a community green space.

Homes in Zuri Gardens will hit the market in early summer of 2026. Final pricing has yet to be determined, but Cole Klein Builders expects it to be in the mid-to-high 200s.

Interestingly, none of the homes will offer garages or driveways, which the developer says will provide a cost savings of $25,000-$40,000 per home. Instead of parking for individual units, 140 parking spaces will be provided.

Each two-story home is comprised of a ground floor printed by HiveASMBLD, using a proprietary low-carbon cement alternative by Eco Material Technologies that promises to enhance strength and reduce CO2 emissions. The hybrid homes will have a second floor built using engineered wood building products by LP Building Solutions. Overall, the homes are designed to be flood, fire, and possibly even tornado-proof.

The "Zuri" in Zuri Gardens is the Swahili word for “beautiful,” a choice that is fitting considering that the parks department will be introducing a five acre park to the project — with 3D-printed pavilions and benches — plus, a three-acre farm is located right across the street. The Garver Heights area is classified as a food desert, which means that access to fresh food is limited. Residents will have access to the farm’s fresh produce, plus opportunities to participate in gardening and nutrition workshops.

Cole Klein Builders created Zuri Gardens in partnership with the Houston Housing Community Development Department, who provided infrastructure reimbursements for the roads, sewer lines, and water lines. In return, CKB agreed to push the purchase prices for the homes as low as possible.

Zuri Gardens also received $1.8 million dollars from the Uptown Tourism Bond, 34 percent of which must be used with minority-owned small businesses. Qualified buyers must fit a certain area of median income according to HUD guidelines, and homes must be owner-occupied at all times. Zuri Gardens already has an 800-person waitlist.

“They’re trying to bridge that gap to make sure there is a community for the homebuyers who need it — educators, law enforcement, civil workers, etc.,” Cole Klein Builders’ co-principal Vanessa Cole says. “You have to go through a certification process with the housing department to make sure that your income is in alignment for this community. It has been great, and everyone has been really receptive.”

Cole has also brought insurance underwriters to visit the site and to help drive premiums below regular rates for Houston homeowners, as claim risks for one of the 3D homes are extremely low.

Tim Lankau, principal at HiveASMBLD, notes that the 3D hybrid design allows for a more traditional appearance, while having the benefits of a concrete structure: “That’s where the floodwaters would go, that’s where you can hide when there’s a tornado, and that’s where termites would eat. So you get the advantages of it while having a traditionally-framed second floor.”

It’s important to note that Zuri Gardens is not located in a flood prone area, nor did it flood during Hurricane Harvey — being flood-proof is merely a perk of a cement house. The concrete that Eco Material Technologies developed is impervious. The walls are printed into hollow forms, which house rebar, plumbing, and accessible conduits for things like electrical lines and smart house features. Those walls are then filled with a foamcrete product that expands to form a “monolithic concrete wall.”

David McNitt, of Eco Material Technologies, explains that his proprietary concrete is made of PCV, and contains zero Portland cement. Instead, McNitt’s cement is made from coal ash and is 99 percent green (there are a few chemicals added to the ash). Regardless, it’s made from 100 percent waste products.

“This is a product that has really been landfilled before,” says McNitt. “It’s coal ash, and it’ll set within 8-10 minutes. It’s all monolithic, and one continuous pour — it’s literally all one piece.”

Eco Material Technologies’ concrete product is impressively durable. A traditional cinderblock wall will crush at around 800 psi, while this material crushes at about 8,000 psi.

“It’s ten times stronger than a cinderblock wall that can withstand hurricanes,” claims McNitt. “I don’t think you’d even notice a hurricane. It’ll be really quiet inside, too — so you won’t get interrupted during your hurricane party. It’s way over-engineered, it really is.”

The second story is built using weatherproof and eco-friendly products by LP Building Solutions. Their treated, engineered wood products come with a 50 year warranty, and their radiant barrier roof decking product blocks 97% of UV rays, and keeps attic temperatures 30° cooler than traditional building materials. These materials, combined with the concrete first floor, will keep heating and cooling costs low — something the folks at HiveASMBLD refer to as “thermal mass performance.”

Texas startup receives $9M to build affordable 3-D printed houses

High-tech homes

In the not-too-distant future, a Texas company's 3-D printed homes will be popping up across the world for a fraction of the cost of traditional homes.

"It's our mission at ICON to reimagine the approach to homebuilding and construction and make affordable, dignified housing available to everyone throughout the world," says Jason Ballard, co-founder and CEO of Austin-based ICON LLC. "We're in the middle of a global housing crisis, and making old approaches a little better is not solving the problem."

The 3-D printed homes startup just raked in $9 million in seed funding from a host of investors, including Fort Worth-based homebuilding giant D.R. Horton; Vulcan Capital, a Seattle investment firm launched by Microsoft billionaire Paul Allen, who died October 15; Austin startup accelerator Capital Factory; Austin real estate developer Cielo Property Group; and San Francisco venture capital firm Oakhouse Partners, which is the lead investor.

At this point, ICON executives aren't sure when their homes will be popping up around town. However, Ballard tells CultureMap, "serious conversations" are underway about bringing these homes to Austin and other places around the world.

In March, ICON reaped tons of press when it unveiled a 350-square-foot 3-D home at SXSW — the first home of its kind to receive a construction permit in the U.S. At the time, ICON executives said the home — constructed of concrete and printed in less than 48 hours by 3-D printing robots — cost less than $10,000. By contrast, the median price in September 2018 of a single-family home in the Austin metro area was $302,250.

ICON's first batch of homes is planned for a project in impoverished El Salvador that's being developed in conjunction with New Story, a San Francisco nonprofit that seeks to eradicate homelessness. The first homes there are scheduled to be printed next year.

ICON is targeting a per-home cost of $4,000 in El Salvador. Relying on technology upgrades, ICON hopes to create each 3-D home in less than 24 hours.

"While prices to print homes will vary from country to country and state to state," Ballard says, "the big takeaway is that downloading and printing a home has the potential to cost half of standard construction costs."

Homes at the development in El Salvador will measure 600 to 800 square feet — around the size of a typical one-bedroom apartment. Eventually, ICON aims to print homes in the 1,500- to 2,000-square-foot range.

Among the advantages of 3-D printed homes cited by ICON are:

  • Speedy construction
  • No manual labor
  • Little generation of leftover construction materials
  • "Tremendous" design freedom

There's a positive environmental impact with this construction process as well.

"Conventional construction is slow, fragmented, wasteful, and has poor thermal properties that increase energy use, increase operating costs, and decrease comfort," Ballard says. "Also, conventional materials like drywall and particleboard are some of the least resilient materials ever invented."

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”

Houston startup raises $6M to scale home-based healthcare platform

fresh funding

As healthcare systems race to expand care beyond hospitals and into the home, investors are placing bigger bets on the infrastructure needed to make that shift possible.

This month, Rosarium Health announced it has raised $6 million in seed funding led by Kalos Ventures, with participation from ResilienceVC, Rock Health Capital, Symphonic Capital, Black Tech Nations Ventures and others.

The investment will help the Houston-based startup continue to build its platform, which features a national network of 800-plus clinicians and 3,000-plus contractors to coordinate home accessibility upgrades and modifications for seniors and people living with disabilities.

For founder and CEO Cameron Carter, the company’s mission grew out of firsthand caregiving experiences.

“From my own personal caregiving experiences, I realized that the benefits exist on paper, but not in reality,” Carter said in a news release. “Families are being left to figure out the paperwork and installations all on their own, which shouldn’t be how this works.”

While Medicare Advantage and Medicaid plans have expanded coverage for home-based services and accessibility modifications, the logistics behind delivering those services often remain fragmented.

Rosarium’s platform coordinates the entire process, from clinical assessments and referrals to contractor management, documentation, reimbursement and installation.

“A clinician can document that a home isn’t safe and a plan can approve a benefit, but there’s no one that’s responsible for making sure the work actually gets done,” Carter says. “We built the missing piece.”

The company was founded in 2021 as Rose Health and was a 2023 participant in the Texas Medical Center’s Accelerator for HealthTech program. It has scaled quickly, building a network of more than 800 clinicians and 3,000 contractors across 34 states.

Rosarium is currently in-network for 1.2 million Medicare and Medicaid lives, with projected coverage expected to reach nearly 4 million by the end of the year, according to the release.

“We’re excited to back Cameron because he and the team at Rosarium are building the infrastructure healthcare needs right now to make the home a safe and comfortable place of care,” Kate Ballinger, investor at Kalos Ventures, added in the release.

As part of the recent investment, Ballinger will join Rosarium’s board of directors.

With eyes on the future, Rosarium plans to grow its partnerships with Medicaid and Medicare Advantage plans, including CalViva and Community Health Plan of Imperial Valley, strengthening its presence in California while expanding access to underserved communities.

Additionally, Carter predicts that home-based healthcare will be part of a broader transformation happening across the industry.

“There’s a growing recognition that health outcomes are shaped by what happens in the home,” he said in the release. “The future of healthcare isn’t just treating people after something goes wrong. It’s creating environments that help prevent those problems in the first place.”
