Medical office and life sciences projects are making a big splash in Houston’s commercial real estate sector in 2023.

The 42Floors commercial real estate website ranks five Houston-area medical office buildings among the country’s 20 largest medical office projects set to open this year. Meanwhile, 42Floors identifies two Houston developments among the 20 biggest U.S. life sciences projects on tap to debut in 2023.

Leading the list of the largest U.S. medical office buildings scheduled to be completed this year is the $1.3 billion, 400,000-square-foot O’Quinn Medical Tower. Set to open April 14 at the McNair Campus of Baylor St. Luke’s Medical Center, the outpatient facility will adjoin the McNair Hospital Tower, which opened in 2019.

The O’Quinn tower will serve as the new clinical home of the Dan L Duncan Comprehensive Cancer Center. The center is a federally designated facility for cancer care and research.

Highlights of the 12-story O’Quinn tower, southeast of the Texas Medical Center, include:

  • Ambulatory surgery center with 12 operating rooms and 10 endoscopy suites
  • 80-bay setup for infusion therapy
  • More than 70 exam rooms
  • More than 850 parking spaces

In all, five medical office properties in the Houston area made the 42Floors list, representing the highest concentration of major projects in any U.S. metro area that are scheduled to open this year. The four medical office properties joining the O’Quinn tower on the list are:

  • Houston Methodist Sugar Land Medical Office Building 4, 159,252 square feet
  • Kelsey-Seybold Springwoods Village Campus, 157,983 square feet
  • Kelsey-Seybold Ambulatory Surgery Center in Clear Lake, 116,000 square feet
  • 1715 Project in Friendswood, 107,000 square feet

A separate 42Floors list ranks Dynamic One, part of Baylor College of Medicine’s TMC Helix Park, as the second largest life sciences project in the U.S. set to come online this year. Houston’s TMC3 Collaborative Building lands at No. 19.

The 12-story Dynamic One project will feature lab space, offices, restaurants, and stores. It represents the first of four buildings planned for the 37-acre, five-million-square-foot TMC Helix Park, which is projected to generate an economic impact of $5.4 billion.

The 42Floors list puts the square footage of Dynamic One’s north tower at 365,000. Organizations involved in the project cite the square footage as 355,000.

The Baylor College of Medicine has signed up as Dynamic One’s anchor tenant. It will occupy 114,000 square feet of lab and office space.

“Baylor College of Medicine is a major force in life sciences discovery and commercialization at TMC. Their move to TMC Helix Park will serve as a catalyst for enhanced collaboration with TMC’s other esteemed Institutions, as well as with industry leaders from around the world,” Bill McKeon, president and CEO of TMC, says in a news release.

Also located at TMC Helix Park, the four-story TMC3 Collaborative Building will span 250,000 square feet. It will contain research facilities for MD Anderson Cancer Center, the Texas A&M University Health Science Center, the University of Texas Health Science Center at Houston, and TMC.

In addition, the TMC3 Collaborative Building will house life sciences companies, the TMC Data Collaborative, the TMC Venture Fund, the Braidwell hedge fund, and venture capital and private equity firms.

Innovation Labs @ TMC set to launch for early-stage life science startups

moving in

The Texas Medical Center will launch its new Innovation Labs @ TMC in January 2026 to better support life science startups working within the innovation hub.

The 34,000-square-foot space, located in the TMC Innovation Factory at 2450 Holcombe Blvd., will feature labs and life science offices and will be managed by TMC. The space was previously occupied by Johnson & Johnson's JLABS @TMC, a representative from TMC tells InnovationMap. JLABS will officially vacate the space in January.

TMC shares that the expansion will allow it to "open its doors to a wider range of life science visionaries," including those in the TMC BioBridge program and Innovation Factory residents. It will also allow TMC to better integrate with the Innovation Factory's offerings, such as the TMC Health Tech accelerator, TMC Center for Device Innovation and TMC Venture Fund.

“We have witnessed an incredible demand for life science space, not only at the TMC Innovation Factory, but also on the TMC Helix Park research campus,” William McKeon, president and CEO of the TMC, said in a news release. “Innovation Labs @ TMC enables us to meet this rising demand and continue reshaping how early-stage life science companies grow, connect, and thrive.”

“By bringing together top talent, cutting-edge research, and industry access in one central hub, we can continue to advance Houston’s life science ecosystem," he continued.

The TMC Innovation Factory has hosted 450 early-stage ventures since it launched in 2015. JLABS first opened in the space in 2016 with the goal of helping health care startups commercialize.
