This year's holiday shopping season is keeping online retailers hopping. Commercial real estate services provider CBRE predicts holiday e-commerce sales in 2020 will exceed last year's by a whopping 40 percent.

But even before Americans were focusing intently on buying holiday gifts, e-commerce had taken off amid pandemic-generated shopping constraints. In the second quarter of this year, online sales skyrocketed by 44.5 percent compared with the same period in 2019, according to the U.S. Census Bureau. E-commerce accounted for a record-high 15.1 percent of total retail sales from April through June.

A forecast from commercial real estate services provider Avison Young indicates the U.S. upswing in e-commerce sales will benefit one segment of Houston's real estate sector more than any other in 2021 — industrial. Riding this year's e-commerce wave, Houston's industrial market will "remain solid" next year, the forecast says.

"Industrial continues to outperform all other asset types," Avison Young's report reads, "but higher vacancies and larger rent concessions will continue in 2021 as the new supply outpaces immediate demand. Online shopping is strong, and national retailers are building large distribution centers and last-mile facilities throughout the metro."

The forecast cites several industrial projects underway or recently leased in the Houston area:

• A 1 million-square-foot spec warehouse under construction in Baytown, near the Port of Houston. It's said to be one of the largest spec industrial facilities underway in the U.S. The developer is Hunt Southwest Industrial Real Estate. The warehouse is set to open in March.
• A 1.5 million-square-foot distribution center under construction in New Caney for home improvement retailer Lowe's. The $65 million project, which will be the largest industrial facility in Montgomery County, is supposed to be ready for occupancy in July.
• A newly completed 402,648-square-foot facility that online retailer Costway is occupying in Pasadena, near the Port of Houston.
• Dunavant Distribution's expansion into a 784,000-square-foot leased property in Deer Park, near the Port of Houston.

Various e-commerce players are relying more and more on regional distribution centers, last-mile distribution facilities, and micro-fulfillment centers throughout the Houston area, according to Avison Young. E-commerce behemoth Amazon is driving a lot of this activity. For instance, the retailer is planning a 1 million-square-foot fulfillment center in Missouri City. That space is scheduled to open sometime in 2021. Meanwhile, an 850,000-square-foot Amazon fulfillment center is on tap for nearby Richmond.

In a third-quarter report, Avison Young noted that 15.1 million square feet of industrial space was under construction in the Houston area and 4.1 million square feet of industrial space had been completed, with net absorption of 1.1 million square feet.

The Port of Houston is helping propel many of the moves in Houston's industrial market. In October, the port notched its busiest month on record, with cargo activity sailing 15 percent above the same period in 2019. Operators of the port hope to begin work on widening of the Houston Ship Channel in 2021.

Nationally, this year's spike in online shopping rocked the retail boat. This surge has produced new generations of retailers and consumers, Avison Young says, and has put pressure on the entire supply chain. Furthermore, it has accelerated chatter about the road ahead for last-mile delivery and brick-and-mortar retail.

"Existing retail space, which was either redundant or surplus to requirements, is being repurposed to facilitate 'click and collect' models," per the report. "Retailers are adjusting the 'front end' consumer-facing component of the store for showroom or experiential space to complement traditional browse-and-buy activity. In-store staff, coupled with technology investments, are being channeled into order picking and back-of-house fulfillment activities."

"Traditional stores were always a combination of the retail and logistics functions; recent trends suggest a renewed recognition of this dual role," the firm adds. "As surplus retail space becomes cheaper and more available, innovations around hyperlocal delivery will be a key part of reimagining the future of retail."
