"There was a lot of forethought that went into this building that made it more expensive but gives flexibility for the county in the future," David Kelly, a managing director and co-founder of Serra Real Estate, told CoStar News.The garage is also an example of how the fast-growing greater Dallas-Fort Worth region, already the nation's fourth-biggest metropolitan area, is considered by some as a good testing ground for future technology that can change real estate. Retailers are testing drones in the suburbs to deliver online orders to doorsteps, while Kroger has an advanced robotics warehouse in the region. As for the future-focused garage, all 1,228 parking spaces are prewired to charge electric vehicles — cars and trucks that weigh much more than gasoline-powered versions. For example, the 2024 GMC Hummer EV pickup weighs more than 9,000 pounds with its battery adding about 2,900 pounds, while the 2024 GMC Sierra 1500 Crew Cab, a full-size pickup reliant on gas, weighs less than 4,800 pounds, according to Kelley Blue Book. With that weight differential in mind, Serra Real Estate ensured the garage's reinforced concrete support beams were designed to support at least 11 million pounds. That's the weight equivalent of 55 blue whales, the world's heaviest mammal at about 200,000 pounds. The garage's design secures its viability for the next half-century to accommodate heavier vehicles, as well as any EV charging innovations, Kelly told CoStar News.
"The uses of garages are changing with electric vehicle charging," Kelly said. "With EV batteries weighing more than gasoline, we have prestressed the garage, so you can check 1,700 electric vehicles into a hotel and it does not collapse. We are future-proofing real estate."The garage also marks a risk: There's no guarantee there are enough electric vehicles to fill all the spots, meaning the investment in the equipment may not be fully realized.
"Generally speaking, there's a 20% increase in the cost of development to future proof" a garage like the Dallas County one, Gonzalez said, and costs go up more when planning for development on top.
"The biggest problem that a garage designed for EVs is the utilities bringing in power can take a lot of space in a mechanical room," Gonzalez of WGI said.Dallas County is expected to ultimately decide what might be built atop the parking structure, but the air rights it can acquire gives it the ability to put a 15-story tower on the property. Kelly said a hotel could make sense as the structure is near to what is expected to be a new convention center.
"The county is looking to the future," he added.Serra Real Estate, under the direction of Dallas County, has begun receiving potential hotel interest in the site atop the parking garage. The county, which receives all parking revenue or any potential EV charging revenue from the garage, will ultimately make any decision on future development at the property. The parking garage has six passenger elevators and one service elevator with infrastructure built into the garage to accommodate two additional elevators if the county wants to add them. Serra Real Estate is working on potential projects such as the Dallas County garage with similar proposals involving municipalities in the Carolinas and Alabama. Serra Real Estate is a municipal advocacy group, said Kelly, who is the former chairman of the Teacher Retirement System of Texas and is a director on the board of Invesco. He has developed over $3.5 billion of real estate in his 35-year career, helping finance more than $50 billion in capital market deals.
