Assignment Follows Interra Capital Group's Acquisition of Class A Property in Houston's West Loop
September 29, 2026
HOUSTON – Transwestern announces it has been retained by Interra Capital Group, to provide Agency Leasing services for Park Towers, a two-building, 552,250-square-foot Class A office complex located at 1233 and 1333 West Loop South in Houston.
Transwestern’s leasing team, led by Senior Vice President Jack Scharnberg and Executive Managing Director Doug Little, will continue to oversee leasing at the property following Interra’s recent acquisition of Park Towers from Regent Properties.
The assignment continues a successful leasing campaign that increased occupancy to approximately 90% under prior ownership and helped stabilize the asset with a roster of high-credit tenants, including Ryan and Huntington Bank.
“We are pleased to be retained by Interra to continue leading the leasing at Park Towers,” said Scharnberg. “Having helped guide the property’s successful lease-up to stabilization, our team is uniquely positioned to build on that foundation. We look forward to working alongside Interra to strengthen the property’s market position and continue attracting high-quality tenants.”
Located just inside Loop 610 at the intersection of West Loop South and Post Oak Boulevard, Park Towers provides convenient access to many of Houston’s most sought-after neighborhoods, retail destinations and business districts. The property features two fitness centers, a casual lounge, a tenant lounge with a state-of-the-art golf simulator and wine storage, a conference facility, Amazon Lockers, an on-site Starbucks and a deli.
“Park Towers is a well-located, well-leased Class A asset in one of Houston’s premier office corridors, and we see meaningful opportunity ahead,” said Jack Polatsek, Founder and CEO of Interra Capital Group. “Transwestern’s team knows this property and its tenants better than anyone, and continuity in leasing was a priority for us from day one. Combined with our hands-on asset management approach and our commitment to continued investment in the property, we are confident Park Towers will remain a destination of choice for high-quality tenants in the Galleria and West Loop.”
