Broadview Real Estate has announced plans for O27, a 32-story office tower spanning 520,000 square feet at 4701 Westheimer Road in Houston. The project involves demolishing an existing extended-stay hotel at the 2-acre site.
Why it matters
The developer identified a gap in the local office market for high-capacity space, marking a significant addition to the Westheimer Road corridor. This project represents the first office building over 500,000 square feet in Houston since 2021.
The proposed 32-story O27 tower covers 520,000 square feet, significantly larger than recent regional projects like the 266,000-square-foot tower at 4100 Westheimer Road. Completion is expected in 2028.

The Home Front
Large-scale office developments in Houston have been sparse since the 2021 completion of the Texas Tower. O27 represents a return to significant, large-footprint construction projects in the city's commercial hubs.
Residents near Westheimer Road should anticipate construction traffic and activity on the site starting after the hotel demolition. Future updates regarding the project timeline may impact local traffic patterns near the Galleria and River Oaks District.
The takeaway
Large-scale commercial projects like O27 can influence neighborhood character and property logistics long before construction begins. Monitor local city notices for updates on road closures or construction schedules as the project progresses toward 2028.
