One Shell Plaza, a prominent office tower in downtown Houston, is set to undergo a $50 million renovation aimed at revitalizing the property and enhancing its connection to the surrounding area. The redevelopment of 910 Louisiana Street, formerly known as One Shell Plaza, will be managed by global developer Hines. The project is expected to be completed in 2027.
The planned upgrades include replacing the building’s ground level with glass walls, adding retail spaces, and introducing green areas. These changes are part of an effort to address high vacancy rates and meet tenants’ increasing demand for more natural light and amenities.
Hines originally constructed the 50-story skyscraper in 1971 as its first major office development. Although Hines sold the property years ago, it has remained involved as manager. Busycon Properties currently owns the building, while Partners Real Estate handles leasing activities.
Shell previously occupied most of the building’s 1.6 million square feet but relocated westward some time ago. Since then, Shell’s former space has been subleased to companies such as NRG Energy. With that lease expiring in December and NRG preparing to leave, occupancy is projected to drop from 86 percent to about 35 percent early next year.
“It’s a conundrum that all landlords are dealing with,” said Mark Janssen, Hines property management director. “Since COVID and working from home, ‘office’ has almost become a dirty word among investors.”
Despite these challenges, Busycon Properties remains optimistic about downtown Houston’s future prospects. According to initial construction filings, the renovation will cost $49.6 million and feature floor-to-ceiling glass facades for increased transparency along street edges intended for food and beverage tenants. Plans also include landscaping improvements with curved paths and shaded seating areas.
Additional amenities will comprise a 5,000-square-foot terrace and tenant lounge overlooking Smith Street, an upgraded fitness center, and a new conference facility spanning approximately 9,000 square feet.
“The redevelopment is focusing on the street life experience in and around the building, which is what tenants are craving,” said Chip Colvill of Partners Real Estate.
Busycon joins other downtown Houston landlords investing heavily in their properties amid changing market demands.
