A full city block in eastern Downtown Houston that has functioned for years as little more than an open-air parking lot is about to become a 12-story parking garage with 2,053 spaces, electric vehicle charging stations, and a skybridge linking it directly to one of the district's tallest towers. The site at 1215 Walker Street, known as Block 95, spans 64,601 square feet and is bounded by Walker, Rusk, Caroline, and San Jacinto streets.
Stream Realty Partners announced the project, which is expected to break ground in 2027, as reported by Chron. The company acquired the site from a Dallas entity affiliated with Parking Systems of America, according to Realty News Report, which detailed the block's precise dimensions and seller background. The garage will feature full-size parking spaces, wider drive aisles, enhanced lighting and security, a parking guidance system, and modern finishes with improved wayfinding, per Chron's reporting.
The new structure will also include a skybridge connecting it to the 46-story 1 Houston Center, tying the garage directly into the broader Houston Center campus that Stream Realty Partners and joint venture partner AustralianSuper acquired in 2025. Kyle Valentine said the acquisition of Block 95 represents another significant investment in the long-term future of Houston Center and downtown Houston, and added that the planned garage will meet the campus's long-term parking needs and accommodate a broader range of tenant requirements, according to Chron.
A Decade-Old Surface Lot Finally Gets Its Turn
Block 95 has been eyed for major development before. Back in 2014, Crescent Real Estate Holdings announced a proposed 30-story, 600,000-square-foot office tower called 6 Houston Center for the same site, complete with a nine-level garage, but the project never broke ground, the same Realty News Report account noted. The block instead sat as a surface lot for more than a decade before Stream Realty Partners' current plans emerged.
This time, the ground level won't be given over entirely to cars. Plans for the 12-story structure include ground-level retail and restaurant spaces designed to keep pedestrian activity alive along the Walker and Rusk street corridors, addressing a common concern that parking garages can turn into blank-walled bunkers in dense urban cores, per Realty News Report.
No City Mandate, Just a Bet on Downtown's Future
Notably, nothing in city code required this garage to be built at all. Under Houston's Market-Based Parking policy, the Central Business District is exempt from mandatory off-street parking minimums, according to the City of Houston, which expanded similar market-based exemptions into Midtown and East Downtown back in 2019. That makes the 2,053-space garage a voluntary commercial investment by Stream Realty Partners and AustralianSuper rather than something the city required.
Once complete, the garage will expand Houston Center's campus parking capacity to a ratio of roughly two spaces for every 1,000 square feet across the 4.6 million-square-foot complex, which includes four Class A office towers — 1, 2, 3, and 4 Houston Center — along with The Highlight at Houston Center, a 200,000-square-foot indoor retail and dining facility, according to a joint venture announcement covered by Bisnow. AustralianSuper, an Australian pension fund, took ownership of the campus in May 2025 after previously supplying a $219 million mezzanine loan to former owner Brookfield Properties back in December 2017, per that same reporting.
Filling Space Left by Departed Tenants
The parking push comes as Houston Center works to recover from a wave of high-profile tenant departures. Chemical giant LyondellBasell vacated 358,000 square feet at 1 Houston Center in 2023, and law firm Norton Rose Fulbright left 350,000 square feet at 3 Houston Center, according to The Real Deal. Those departures left significant vacant space across the campus's four towers even as ownership pursued a broader repositioning strategy.
There has been some leasing momentum since. The Real Deal reports that Stream Realty Partners signed energy provider NRG Energy to relocate its corporate headquarters into 245,000 square feet at 3 Houston Center, a win amid an otherwise soft downtown office market. Real estate market data from Partners Real Estate showed Downtown Houston's office submarket facing a 31.8 percent vacancy rate in the first quarter of 2026, among the highest in the region, the outlet's later coverage found.
Downtown Houston's broader commercial real estate market has seen steep repricing amid these pressures. Hoodline previously reported on a cut-rate deal in which the 40-story Jefferson Towers office complex and its adjacent garage sold for $66 million in January 2026, a steep drop from its previous $120.4 million tax appraisal.
Who's Leading the Project
Blake Bell and Ramsey March will oversee development of the Block 95 garage, according to Chron's reporting, while Matt Asvestas and Ryan Barbles will continue to lead leasing efforts for Houston Center. Open questions remain about the project's total construction cost and what specific design approvals the city will require before the 2027 groundbreaking, details that have not yet been disclosed publicly.
