Downtown Houston has been fortunate to benefit from a transformation over the last couple of decades. Beautiful green spaces, luxury high-rises and hotels, restaurants, and updated arts and entertainment facilities are home to impressive art installations, farmers markets, major professional sporting events, and more. On the flip side of this, Houston’s central business district has seen a steep decline in commercial occupancy, struggling to bounce back to pre-COVID levels.

Houston is not alone in experiencing this situation. Nationwide, commercial vacancies are becoming increasingly noteworthy as the gap between residential rental rates and stagnant wages widens. Low-income earners, folks making between $20,000 and $30,000 annually (typically minimum wage employees, students and seniors living on Social Security), have been joining the ranks of the unhoused at an alarming rate due to the scarcity of affordable housing. Armchair economists and the like have been arguing for years that cities should repurpose these untapped resources into an opportunity to create dignified affordable housing that would keep those at risk off the streets and close to public transit options.

Pew Charitable Trust, along with international architectural firm Gensler, recently released their findings from a study on the subject — with Houston being one of two markets studied. The “Flexible Co-Living Housing Feasibility Study” found that converting Houston’s empty office buildings to communities of micro-apartments is, well, feasible.

“In the current climate of high construction costs, interest rates, building expenses, and rising rents, this project looks at the conventional office-to-residential conversion in a different way by leveraging the existing building infrastructure to reduce costs on a per unit basis,” Brooks Howell, principal architect at Gensler, tells CultureMap. “The result is a new housing typology, a co-living concept, that can provide affordable housing to the large and growing number of lower income single-person households in an urban context.”

The numbers
HUD reported that in 2024 homelessness was at an all-time high of 770,000 persons, up a staggering 18 percent from the prior year. Houston is on the low end of the national average, with a reported 3,270 homeless persons (4/10,000 Houstonians). CoStar data shows that Houston’s central business district contains 88 office buildings of over 50,000 square feet, 19 of which show reported vacancy rates of over 30 percent. As of November 2024, the median rent in Houston for an apartment was $1,297. The proposed rental rate for a furnished micro-apartment in a converted office building in downtown Houston is $700 — all inclusive, with zero move-in costs, as the units are fully furnished.

“The U.S. has a housing shortage of 4-7 million homes, which has driven rents to an all-time high and made it hard to save to buy a home,” Alex Horowitz, a project director for Pew Charitable Trust and a co-author of the study, adds. “Houston has one of the highest office vacancy rates in the U.S., but office layouts often don't work well for apartment conversions and carry high costs. This study finds that converting offices to dorm-style housing is cost-effective and can enable low rents — about $700 per month to live downtown. That could make a real difference for people struggling with high housing costs while revitalizing downtown.”

Co-living explained
Co-living is hardly a new concept. “Single room occupancy” dwellings, or SROs, were extremely common until about 1950. It’s worth noting that during the height of its popularity, homelessness was rare. The co-living model allows for a private furnished space, while bathrooms, kitchens, and laundry are shared facilities — much like a college dormitory. With 40 percent of renters being single occupants, this model promotes socialization and community, something that has been trending downward since the pandemic.

Wesley LeBlanc, principal analytics director for Gensler Chicago, adds that this elevated dorm situation is a “jumping off point for a number of models,” noting that there are six variations from the one in the study. LeBlanc encourages people to “Think beyond the conventional. A whole world of housing solutions come out of this.”

What to expect in a typical converted building
The Pew/Gensler report proposes a prototypical building standard of 24 floors, 19 of which are residential, with 60 micro-apartments per floor, or 1,140 residential units per building. Each floor would offer six shared kitchen areas, five larger shared living spaces, two smaller shared living spaces tucked into interior hallways, two central shower areas with five private shower rooms each. Two shower rooms would include toilets and sinks, plus two additional toilet rooms with four toilets and two sinks. The total comes to 10 showers, 12 toilets, and 14 sinks per floor. Two laundry rooms, each with three washers and dryers, would also be available per floor.

The high cost of converting office buildings into fully plumbed, individual studio apartments can be cost prohibitive, leading a pragmatic Howell to ask: “What if we didn’t demo everything?” The utilization of existing centralized plumbing on each floor saves an average of 25-35 percent in construction costs that would arise from running new plumbing to each unit.

The ground floor would consist of a main lobby, management office, and 10,000 square feet of retail space. Floors two through four would be reserved for parking, while the fifth floor would offer 10,000 square feet of Class B office space as well as amenities like the gym.

While subsidies will be required for the conversion, the same will not be true once the development is out of the construction phase. The co-living model is projected to cost around one-third of the cost of converting an office building to individual studio apartments or constructing new affordable housing.

Micro-apartments details
Each individual unit is designed to be 151 square feet, approximately the size of a modest hotel room. Furnishings include one extra-long twin bed (bedding included), a desk, chair, nightstand, standard-depth half-sized fridge, storage shelf, and cabinet. Units would have solid-core wooden doors and appropriate sound insulation — all for a tidy $700 per month.

Pricing has been a key factor in determining this configuration for affordable, urban housing. “Lowering the cost of housing to manageable levels enables residents to spend more on the other financial needs of their lives, which has broad implications for quality of life and well being,” LeBlanc explains.

Houston medical device startup implants artificial heart in first human patient

big win

Heart health tech company BiVACOR and The Texas Heart Institute announced that they successfully implanted the company's first Total Artificial Heart in a human at Baylor St. Luke’s Medical Center in the TMC.

The milestone is part of an FDA-approved early feasibility study that will test the safety and performance of the TAH device, which is based on a magnetically levitated rotor that takes over functions of a failing heart while a patient is awaiting a heart transplant, according to a statement from the organizations.

The "bridge-to-transplant" device could support an active adult male, as well as many women and children suffering from severe biventricular heart failure or univentricular heart failure.

"With heart failure remaining a leading cause of mortality globally, the BiVACOR TAH offers a beacon of hope for countless patients awaiting a heart transplant,” Dr. Joseph Rogers, president and CEO of THI and national principal investigator on the research, says in a statement. “We are proud to be at the forefront of this medical breakthrough, working alongside the dedicated teams at BiVACOR, Baylor College of Medicine, and Baylor St. Luke’s Medical Center to transform the future of heart failure therapy for this vulnerable population.”

BiVACOR received approval from the FDA for the early feasibility study in late 2023 and has four other patients enrolled in the study. At the time the study was approved, 10 hospitals were enrolled as possible sites.

“I’m incredibly proud to witness the successful first-in-human implant of our TAH. This achievement would not have been possible without the courage of our first patient and their family, the dedication of our team, and our expert collaborators at The Texas Heart Institute ... our TAH brings us one step closer to providing a desperately needed option for people with end-stage heart failure who require support while waiting for a heart transplant. I look forward to continuing the next phase of our clinical trial,” Daniel Timms, PhD, founder and CTO of BiVACOR, adds.

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. Globally, only about 6,000 heart transplants are performed each year, while 26 million people worldwide are affected by heart failure.

BiVACOR was founded in 2008 and maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, the company has raised nearly $50.8 million, according to CB Insights. The company raised $18 million in 2023, and $22 million in 2021.

Earlier this year, BiVACOR named a new CEO in Jim Dillon, a longtime executive in the medical device sector.

Last summer, Rogers joined the Houston Innovators Podcast to share his excitement with THI's innovations.

Houston health tech co. lands NIH grant for AI cancer prediction tool

fresh funding

Houston-based CellChorus and Stanford Medicine were recently awarded a Phase I Small Business Innovation Research grant for the company's AI platform to test how certain cancer patients will respond to therapies.

The funding comes from the National Cancer Institute of the National Institutes of Health. According to a filing, the grant totaled just under $400,000.

CellChorus, which spun out from the University of Houston’s Technology Bridge, has developed TIMING (Time-lapse Imaging Microscopy In Nanowell Grids), which analyzes the behavior of thousands of individual immune cells over time and can identify early indicators of treatment success or failure.

The company will work with Stanford's Dr. David Miklos and Dr. Saurabh Dahiya, who have built the Bone Marrow Transplantation and Cell Therapy Biobank. The biobank manages and stores biological samples from patients treated at their clinic and in clinical trials.

"Predicting which patients will achieve durable responses after CAR-T therapy remains one of the most important challenges in the field,” Miklos said in a news release. “We aim to uncover functional cellular signatures that can guide treatment decisions and improve patient outcomes.”

The project will specifically profile cells from patients with relapsed/refractory large B-cell lymphoma (r/rLBCL). According to CellChorus, only about half of r/rLBCL patients who receive CAR-T therapy "achieve a durable, long-term remission." Others do not respond to therapy or experience relapse.

“The sooner we know whether a cancer therapy is working, the better. To maximize patient benefit, we need technology that can provide a robust and early prediction of response to therapy. The technology needs to be scalable, cost-efficient, and capable of rapid turnaround times,” Rebecca Berdeaux, chief scientific officer of CellChorus, added in the release. “We are excited to work with Drs. David Miklos and Saurabh Dahiya and their colleagues on this very important project.”

CellChorus has previously received SBIR grants from federal agencies, including a $2.5 million award in 2024 from its National Center for Advancing Translational Sciences (NCATS) and a $2.3 million SBIR Fast-Track award from the National Institute of General Medical Sciences in 2023.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.

Houston quantum energy chip startup emerges from stealth with $12M round

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”
