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.

America's first Ismaili Center set to open in Houston in December

Sneak Preview

The long-awaited Ismaili Center, Houston is set to open to the public next month. The 11-acre site has been painstakingly designed and constructed to offer indoor and outdoor public spaces for Houstonians to enjoy, connect, and engage. As the only Ismaili Center in the United States — and seventh in the world — it joins its international communities in London, Vancouver, Lisbon, Dubai, Dushanbe, and Toronto.

Nearly 20 years in the making, the Ismaili Center, Houston features a prayer hall, rotating art installations, a black box theater, a cafe, numerous social halls for weddings and other events, and nine acres of outdoor space and landscaped botanical gardens. Involved parties hope that the community will see the space as an extension of the neighboring parks along the bayou, and have included a garden entrance to the north lawn and gardens at the corner of Montrose Boulevard and Allen Parkway.

While Houston is known for its many community engagement centers, the architects and designers believe that the seamless integration of indoor and outdoor spaces sets the Ismaili Center, Houston apart from all others.

“What we know is the connections between buildings, environment, quality of life, and landscape — this is nothing new,” structural and facade engineer Hanif Kara says. “But, certainly, it’s hard to see that in other developments, particularly when they are done by developers. It’s quite difficult to find community spaces, and to see how quality of life is improved for everyone. I think we’ve all experienced that kind of hope that it will play out something like this.”

Designed by Farshid Moussavi Architecture and Nelson Byrd Woltz Landscape Architects, the remarkable 11-acre site is designed both to receive LEED Gold certification and to withstand the tests of Houston’s sometimes extreme weather conditions.

Principal architect Farshid Moussavi looks forward to seeing the Houston community utilize the space she’s worked so hard to deliver: “We’ve given the hardware to the community, now the software needs to come in. So I hope that there will be music recitals, or lectures, or book fairs, or other kinds of markets that can happen—even simultaneously. This is not an experiment, it’s the seventh in the world.”

Community welcome events are scheduled for December 12 and 13, but, until then, here are 10 features and things to know about the Ismaili Center, Houston.

What is the Ismaili Center, Houston?

“The use of the building is really meant for, or our hope, is that we are able to—on an enhanced view of what the community does today—have engagement on service projects, arts and culture, interfaith dialogue, and even just in bringing people together,” Omar Samji, Ismaili Council for the United States of America, says. “The notion of bringing people together in a place where it is easy to create connections because it’s an open space, and because it’s specifically designed to be a place where people interact and where people find commonality. Because whether you’re out in the gardens, or on the environs, or in the atrium, this enables connection.”

Who is His Highness the Aga Khan?

His Highness Prince Rahim Aga Khan V is the 50th hereditary Imam (spiritual leader) of the Shia Ismaili Muslims and a direct descendant of the Prophet Muhammad. He was educated at Philipps Academy in Andover and Brown University (Class of 1995). He became Imam in February 2025 upon the passing of his father, His Highness Prince Karim Aga Khan IV.

The Aga Khan promotes an understanding of Islam rooted in values of generosity, tolerance, pluralism, environmental stewardship, and the shared unity of humanity. He also chairs the Aga Khan Development Network (AKDN), one of the world’s largest private development agencies, which works across more than 30 countries to improve quality of life for marginalized communities regardless of faith or background.

The scale

The center stretches across an 11-acre site along Montrose Boulevard, from West Dallas to Allen Parkway. The physical building is 150,000 square feet, leaving nine acres for garden spaces on both the north and south sides of the building. The south side of the property is more formal, with gardens and community spaces that flank an 80-foot reflection pool and other water features. The gardens on the north side of the building are more informal, but densely planted and vast.

The creation

The development of the Ismaili Center was led by the Ismaili Council. It was initiated by His Highness Prince Karim Aga Khan IV (1936-2025), and completed under the leadership of his eldest son, Prince Rahim Aga Khan V.

The project was designed and constructed by a team of both local and international firms. Farshid Moussavi Architecture joined forces with structural and facade engineer Hanif Kara, co-founder and creative director of AKT II. DLR Group is the architect and engineer of record, while contractor McCarthy Building Companies built the project. Thomas Woltz, senior principal and owner of landscape architecture firm Nelson Byrd Woltz, along with principal Jeff Aten taking lead on the nine acres of garden space. The project is targeting LEED Gold certification.

The focus on native Texas plants and trees

The center will be recognized as a leading cultural asset for the City of Houston, complementing nearby institutions such as The Menil Collection, Rothko Chapel, Asia Society Texas, and the Museum of Fine Arts, Houston. While the surrounding gardens will add to the other notable Nelson Byrd Woltz projects within close proximity at Memorial Park, Rothko Chapel, and Rice University.

“We’ve been building massive projects in Houston for 12 years,” Woltz says. “We know the horticultural community in the region, and we did a deep, deep dive in ecological research to understand ‘What are the native plants of whatever region?’ It’s just baked into our process. Right when we are starting any project in Houston—right to the river. Look at the soils, ‘What are the plants appropriate to that place?’ Its solar aspect, its humidity, it’s moisture in soils, the shadow of the building.

But then, this idea of taking a section across the state of Texas, so that each of those distinct ecological regions is represented by one of the terraced gardens — so it’s very clear. It’s a diagram of the state of Texas and all of its native plants. This is functioning like a botanic garden and a repository for biodiversity — this is work in service.”

The eco-friendly exterior

The exterior of the building is clad in stone, a durable material with low embodied carbon. The stone cladding is a rainscreen over in-situ ‘fair-faced’ concrete walls, exposed on the interior to minimize additional material use. The concrete mix used has replaced 35-62 percent of Portland cement with fly ash and slag, reducing CO2 emissions by roughly 30 percent compared to standard mixes. The exterior stone rainscreen uses smaller tiles to increase the stone yield, utilizing 20-25 percent more of the irregular blocks they are cut from. This reduction in waste has also lent itself to crafting the cladding in a unique way.

The tessellation of the stone pieces changes across the building's surfaces to create different patterns on different sides of the buildings and at the corners. Relief stone tiles are used to add texture to the facades.

The space for outdoor events

The north-facing botanical gardens that will accommodate the 200-year flood plain offer a 27 foot gradient toward the building. This allowed for various levels of seating and gathering areas that culminate at an elevated terrace that will act as a stage for various events such as plays and concerts. Attendees can stretch out and enjoy the shows from an extensive lawn area that is surrounded by dense gardens of native trees and plants.

The black box theater

A 2,600-square-foot black box multipurpose space which seats 125 people is found on the second floor of the building’s west wing. It can host public events, such as exhibitions, film screenings, theatrical performances, music recitals, and other artistic programs throughout the year. It will also serve as a flexible space for teaching and learning. With acoustic isolation to surrounding spaces and the mechanical mezzanine above, it is designed to operate simultaneously without disrupting other events in the building. Design includes an upper-level control room, pipe grid, and flexible drapery and seating configurations to allow for a wide variety of programming.

The cafe

The center’s café is a 1,600-square-foot, double-height space located in the west wing (Montrose side) that opens onto an enormous terrace, offering visitors the option to enjoy their coffee or food outdoors. The terrace near the cafe is lined by an exterior wall and long, trough-style fountains that aid in noise reduction from Montrose Boulevard. The second-floor wall overlooking the Café is fully glazed, creating visual connection with the levels above.

The prayer hall

The prayer hall is 12,240 square feet, featuring a unique structural system of seven interlocking squares, formed from steel beams spanning the 115-by-115-foot open space. These beams are clad in concrete to enhance durability, beneath which lies a two-layer perforated aluminum ceiling with integrated diffused lighting. Its intricate pattern recalls the traditional jālī screens of Islamic architecture creating a soft, seemingly infinite ceiling effect, adding to the serenity of the prayer hall.
