E-Commerce and Last-Mile Fulfillment Construction in Ennis, Texas

Online retailers that need next-day reach into the Dallas core look for sites south of the city where a building can be larger than anything in the urban grid, and Ennis fits that search. On the east edge of Ennis, Interstate 45 has exits numbered 247 to 255, while U.S. 287 wraps the southern side. A fulfillment operator can load trucks bound for the metro, for the Gulf Coast route or for the east, all from one yard.

Loloi, Inc. gives the market a recent marker. Governor Abbott announced on December 19, 2025 that the company will place a distribution facility of over 1 million square feet in Ennis, with $20 million invested and 380-plus new jobs. A building of that scale shows what a modern e-commerce user wants: high clear height, a long dock wall, wide truck courts and a big parking field for shifts. Developers who want to compete for similar tenants need shells that can meet those specifications.

We build that kind of space and price it from the truck court inward. If you are evaluating a site and have not picked a tenant, our fulfillment and e-commerce center work shows the layouts we start with. Because parcels and returns often move through the same building, we also plan space for return processing, pack stations on a mezzanine, and a surge area for the weeks around peak.

Hitting a peak-season delivery date

E-commerce tenants plan around the holiday peak, and the date they must have racking and conveyor installed is fixed long before a building is finished. We work backward from that date. The sequence runs from permit to site work, slab, panel erection, roof, dock equipment and power, and we mark the point at which the racking contractor can begin.

Long-lead items decide more schedules than weather does. Electrical gear, dock levelers and overhead doors can take months, so we release them as soon as the budget is approved. Turnover is staged where it helps, with the main floor handed over first and offices or mezzanine finished while the tenant fits out the operation. A last-mile user may also want a parking lot for delivery vans ready before the building, and we can reorder the paving to suit.

Blackland Prairie soils and the Bardwell watershed

Ennis sits in the Blackland Prairie, known for dark, expansive clay. Lake Bardwell, built for flood control within the Trinity River Basin, is southwest of the city. Those two facts shape site work: heavy clay needs moisture conditioning and carefully detailed slabs, and drainage planning must account for runoff moving toward the Trinity system.

We rely on the geotechnical report to decide how deep to treat the subgrade and how to build the truck court. Retention and detention basins can take a surprising share of a site, so we lay out the building, the court and the basin together, rather than fitting one around the others. Highway 34 threads the town center and offers a local alternative to the interstate, which helps when a driveway has to sit away from the ramps.

Where an Ennis fulfillment budget goes

For a large e-commerce box, the largest budget lines are the structure, the slab, the electrical service and the site. Slab quality matters more for fulfillment than for plain storage, because automation and narrow-aisle equipment need flat, level floors. Our super flat floor slabs detail how we control.

Power is the second watch item. Conveyors, sorters, charging stations and lighting add load, and the utility may need time to extend service. A tenant's automation plan should be known at budget time, or the electrical allowance should be generous. Paving is the third: a field of employee parking and a deep truck court can add up to a large share of the site cost, so we price them as separate lines.

Who uses space in Ennis

Industrial neighbors give a clue to the labor and freight mix. A 205,000-square-foot IKO roofing plant on a 42-acre site came online, per a July 17, 2025 report, as one step in a phased $60 million program that could add up to 90 positions. Plants like this ship by truck and sit near distribution users who want a stable workforce.

Our e-commerce fulfillment and retail distribution clients are the largest group, followed by manufacturers who store finished goods and carriers who stage freight. We design flexible buildings so a user can change product lines without moving walls.

Building the shell before the tenant signs

Some developers in Ennis will start a shell without a user, because a ready building wins deals. We help them set a design that serves the broadest tenant group: 36-foot clear height, wide interior bays, ESFR-ready sprinklers and plenty of dock positions. Cost control comes from simple geometry and repeatable details, and the second building on a site can reuse the first one's drawings.

On a build-to-suit, we move faster by sharing the tenant's layout with the design team from the start. In both cases, we schedule, coordinate and inspect the trade partners and give the owner a clear weekly report.

Rail, docks and yards

Union Pacific alone runs trains through Ennis, keeping a yard there that serves as the local base for the Ennis Subdivision. Rail is not necessary for most e-commerce users, but it matters for those shipping heavy goods or bulk materials, and it affects land value. If rail is part of your plan, we coordinate track, switches and loading doors early.

Truck-side services are more common. We price dock equipment and levelers, trailer parking and lighting as part of the main package, and we can phase yard expansion for when the volume grows. Owners comparing nearby sites should also look at Mesquite, where rail and highway meet closer to the city, and at Grand Prairie.

Common Questions

How big can an e-commerce building be in Ennis?

The Loloi announcement involves more than a million square feet, so large buildings have a place in the market. Smaller buildings of 150,000 to 400,000 square feet are common for regional operators. We size the building to the product, the automation and the labor plan.

Does Interstate 45 matter for last-mile delivery?

Yes. It provides a direct route toward Dallas, and the connection to US 287 adds options. Drivers and dispatchers care about how many minutes a route saves, so we map actual access before recommending a site.

Can clay soils be built on without problems?

Yes, if the design addresses them. We use treated subgrade, moisture control and joint layout based on the geotechnical report. Skipping those steps risks cracked floors and uneven pavements, and the repair usually costs far more than the treatment would have. We also keep records of the subgrade work so the owner has proof for the lender and the tenant.

How long does a fulfillment building take?

A typical shell takes 10 to 14 months from permit to turnover, depending on size, weather and equipment lead times. A phased turnover can let the tenant start earlier.

Should I build a speculative shell in Ennis?

If you have land, capital and a view of tenant demand, it can pay. We price the shell with options for later tenant work and help you decide how much to include up front.
