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.

Air taxis network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” She added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.
