5858 Westheimer in Houston’s Tanglewood submarket trades to new owner

HOUSTON, Nov. 19, 2025 –  JLL Capital Markets announced today that it has arranged the sale of 5858 Westheimer, an eight-story, 130,735-square-foot office building in Houston, Texas.

JLL represented the seller, a special servicer, in the transaction. Geirin LandPark Westheimer, LLC purchased the asset for an undisclosed amount.

This acquisition marks the second office asset acquired by Geirin LandPark in this immediate corridor, following its recent purchase of 2603 Augusta, a 16-story Class A office tower located directly across Augusta Dr. Together, the two buildings create a complementary, two-building portfolio along Westheimer, positioning the ownership team to capture tenant demand across both properties and contribute to the continued revitalization of the Galleria/Uptown office market.

5858 Westheimer was built in 1981 and is currently 47% leased to diverse rent roll of 10-plus tenants. The Class B building features a 300-space parking garage and surface parking. New ownership plans to implement a targeted repositioning program at 5858 Westheimer, including lobby and common-area upgrades, refreshed branding and signage, move-in-ready spec suites and coordinated amenity enhancements with 2603 Augusta.

The property is positioned on a 2.08-acre site at the intersection of Westheimer Rd. and Fountain View in Houston’s Tanglewood submarket, just west of the Galleria and Uptown neighborhoods. 5858 Westheimer is convenient to many of the city’s most affluent residential neighborhoods, including The Villages, River Oaks, Briar Forest and Memorial. In addition, the property is easily accessible to the greater Houston area via Interstates 10 and 610, Highway 69 and the Westpark Tollway.

“With the acquisition of 5858 Westheimer, we now control two highly visible buildings along this key stretch of Westheimer and can offer tenants everything from efficient, value-oriented office space to fully amenitized Class A environments across our 5858 Westheimer and 2603 Augusta properties,” said Bill McGrath, Founding Partner of LandPark Advisors. “Our plan is to modernize 5858 Westheimer and integrate it into the broader amenity package underway at 2603 Augusta.”

Management and leasing will be handled by LandPark Commercial.

JLL Capital Markets’ Investment Sales and Advisory team representing the seller was led by Senior Director Rick Goings and Analyst Dawson Hastings.
