A 32-story office tower with a curving, glass-wrapped facade is headed for the stretch of Westheimer Road between Uptown/Galleria and River Oaks, where Broadview Real Estate wants to replace a recently shuttered hotel with more than 520,000 square feet of trophy workspace. The developer has released renderings of the project, which it has named O27, and is eyeing a 2028 completion date.
A Sinuous Design for a Prime Westheimer Corner
The project, covered by Houston Business Journal, takes its name from the surrounding 77027 ZIP code. Austin-based STG Design is the architect behind the tower, which is planned with a fluid, curved facade wrapped in triangular glass panels meant to resist the rigid verticality of a typical office block, according to Realty News Report. The design leans into a hospitality- and luxury-retail-inspired look rather than a standard corporate box.
The 1.66-acre site at 4701 Westheimer Road currently holds a former Extended Stay America Suites hotel that closed in 2025. Long before the hotel, the parcel spent more than three decades, from 1966 to 1998, as the home of Tokyo Gardens, one of Houston's early Japanese restaurants, the outlet notes.
Neighboring a Wave of Westheimer Redevelopment
O27 would rise directly across Westheimer from Greenleigh, an ongoing commercial redevelopment converting the former Hotel Derek, the same reporting shows. Another Westheimer project is 100 Park Place, a 17-story, 250,000-square-foot speculative office tower at 4100 Westheimer Road where Stonelake Capital Partners broke ground this autumn, as Hoodline previously reported in its coverage of that nearby project breaking ground.
Broadview's push into ground-up Houston development follows its move deeper into the city's commercial lending market. In December, an affiliated entity, Broadview Capital LLC, issued a $13 million loan maturing in January 2027 to help keep downtown Houston's vacant 44-story former Exxon tower at 800 Bell out of foreclosure, a deal Hoodline covered at the time.
Why a Developer Is Betting Big on Trophy Space
The O27 proposal arrives amid a split market. Overall Houston office vacancy has stayed above 20% in 2026, but direct vacancy in top-tier trophy buildings fell to between 8.5% and 9.1%, its lowest level in a decade, driven by strong flight-to-quality tenant demand, according to Avison Young. That scarcity has pushed pricing power upward: trophy office asking rents reached $56.70 per square foot by mid-2026, the firm found.
Supply constraints are compounding the trend. Houston's total office construction pipeline dropped to a record low of 1.3 million square feet in the third quarter of 2026, with more than 85% of that space already pre-leased, according to Oxford Partners. With so little uncommitted trophy inventory in the pipeline, Broadview and Stonelake appear to be wagering that premier, amenity-rich space between Uptown and River Oaks can draw elite occupiers away from aging buildings elsewhere in the metro.
