HOUSTON – Transwestern announces two leases totaling 54,248 square feet at 811 Main, a 974,884-square-foot, Class AAA office tower in downtown Houston. Transwestern’s Eric Anderson and John Heard represented ownership, BG Holdco, LLC, in the negotiations.
Two Sigma signed a 27,485-square-foot direct lease, transitioning from its previous position as a subtenant within the building. Latham & Watkins expanded its space by 26,763 square feet, bringing the global law firm’s footprint to 103,336 square feet. Both transactions were negotiated on behalf of the tenants by CBRE, with Jon Lee and Claire Douthit representing Two Sigma and Scott Gamber and Craig Reicher representing Latham & Watkins.
These leases add 54,248 square feet of positive momentum to the property, following the recently announced 187,492 square feet of new leasing activity. Currently 93% occupied, the building highlights the sustained flight-to-quality trend, as well as a clear preference among tenants for highly amenitized properties backed by strong, hands-on ownership.
“The conversion of an existing subtenant to a direct lease, alongside the expansion of a globally recognized law firm, underscores both the quality of this asset and the confidence tenants have in its ownership,” said Eric Anderson, Executive Managing Director at Transwestern Services. “We continue to see organizations make long-term commitments to premier office environments that support employee experience and operational performance.”
Located at 811 Main Street in the center of Houston’s CBD, the property benefits from exceptional connectivity and accessibility. Situated at the convergence of the Metro Rail Line, directly across from Finn Hall, and featuring full tunnel connectivity, the building offers strong walkability and convenience for tenants and employees alike.
811 Main features a robust amenity offering, including a Level 21 amenity center with a 150-person auditorium, conference facilities and a tenant lounge, as well as a fitness center and onsite food options. The tower is LEED Platinum certified and WELL Health and Safety certified, further enhancing its appeal to organizations focused on sustainability and employee well-being.
