Houston Developer Breaks Ground on 544-Acre Mixed-Use Mega-Project in Seguin

Houston-based NewQuest Properties has broken ground on Seguin Exchange, a 544-acre master-planned, mixed-use development positioned along the booming Interstate 35 corridor in Seguin, roughly 35 miles northeast of downtown San Antonio. The massive project represents one of the largest ground-up commercial real estate undertakings in the region, aiming to capitalize on the explosive population growth connecting the San Antonio and Austin metropolitan areas.

According to Shopping Center Business, the development firm originally acquired the sprawling land parcel with a long-term vision for regional expansion. Now, with dirt officially moving, the project is set to deliver a large-scale mix of industrial, retail, residential, medical, and hospitality uses designed to serve the influx of new residents and businesses migrating to the Guadalupe County submarket.

Key Details

• Developer: NewQuest Properties (Houston, Texas)
• Location: Seguin, Texas (northeastern outskirts of San Antonio)
• Site Size: 544 acres
• Property Type: Mixed-use (industrial, retail, residential, medical, hospitality)
• Project Status: Construction underway

The project’s program is anchored by approximately 2 million square feet of industrial space across more than 250 acres, alongside roughly 750,000 square feet of retail, restaurant, and entertainment space. Multifamily residential, medical, and hospitality uses round out the development. In a sign of early industrial demand, KTH Parts, an Ohio-based automotive supplier, has signed a 40-acre ground lease, with construction on that building expected to begin later in 2026. NewQuest is also reporting approximately 400,000 square feet of retail space in active lease negotiations. Infrastructure work—utilities and roads—is expected to be in place by end of 2026, with first retail openings targeted for late 2027 and the bulk of retail and restaurant tenants delivering in 2028.

Market Context

For commercial real estate professionals, the launch of Seguin Exchange underscores a broader trend of decentralized development along the San Antonio-Austin corridor. Often referred to as the Austintonian mega-region, this geographic zone has absorbed billions of dollars in industrial, residential, and retail investment over the past five years. Seguin, specifically, has emerged as a highly desirable submarket due to its position along the Interstate 35 corridor, combined with readily available land priced at a steep discount compared to core Bexar and Travis counties.

The retail implications are substantial. As master-planned communities and industrial users continue to populate the area, the local daytime population is surging. Retailers are actively chasing rooftops into these exurban rings. A 544-acre footprint gives NewQuest the scale necessary to create a true live-work-play destination, capturing consumer dollars that might otherwise flow into New Braunfels or central San Antonio.

Furthermore, the project highlights a competitive shift among Texas developers. While firms like Hillwood and Howard Hughes have dominated headlines with massive North Texas land plays, Houston-based outfits are increasingly looking toward the Central Texas corridor to deploy capital. Seguin Exchange will likely serve as a bellwether for future commercial absorption rates in the area, providing brokers and investors with critical data points regarding rent escalations and tenant demand in San Antonio's northeastern exurbs.
