The largest homebuilder in the country just made one of the biggest bets yet on robots in home construction. On October 13, 2026, D.R. Horton announced a multi-year agreement with Promise Robotics, a Toronto company that uses AI-guided robots to build the structural pieces of a house inside a factory. The deal covers more than 1,250 homes.
You may have seen the headline going around that robots can now frame a two-story house in 8 hours. That is close, but the full story is more interesting, and it says a lot about where new construction is heading.
What the deal actually is
- Who: D.R. Horton, the largest U.S. homebuilder by number of homes closed, and Promise Robotics. D.R. Horton is Promise's first U.S. customer.
- How many homes: more than 1,250, mostly single-story, single-family homes.
- Where: the Phoenix, Arizona area. Promise is opening its first U.S. factory there, with production expected to start in early 2027.
- How it works: Promise calls it "factory as a service." Promise owns and runs the factory, robots and software. D.R. Horton sends its existing house plans, and Promise delivers finished components that crews set in place on the lot.
- Money: financial terms were not disclosed.
For scale, 1,250 homes is about 1.5% of the roughly 84,900 homes D.R. Horton closed in fiscal 2025. This is a pilot, not a company-wide switch.
Can a house really be framed in 8 hours?
Here is where the headline needs a little context. Promise's CEO, Ramtin Attar, told HousingWire that framing a typical 1,800-square-foot, two-story home with a basement and attached garage takes about eight hours. That figure covers putting the structure together, not building the whole house. Plumbing, electrical, roofing, drywall, finishes, inspections and everything else still follow.
The reason it goes so fast is that most of the work has already happened in the factory. Robots build the wall panels, floors, stairs and roof pieces indoors, with every stud and opening cut to the plan. On site, the crew is assembling large finished pieces instead of cutting and nailing individual boards.
Also keep in mind that the 8-hour example is a Canadian-style home with a basement. The Phoenix homes in this deal are mostly single-story, so the work will look a little different there.
Is this new?
Not entirely. Promise has already completed more than 200 homes in Canada for builders including Mattamy Homes, Brookfield and Hopewell, from factories in Edmonton and Calgary. It is under contract for just over 2,500 homes across several builders. What is new is a builder the size of D.R. Horton signing on. The company says it plans to add HVAC, plumbing, insulation and drywall to what its factories produce over time.
Why builders want this
D.R. Horton described its goals as faster build times, more production capacity, and more consistent, predictable results. Framing is one of the trades most squeezed by the construction labor shortage, and a frame built indoors is not waiting on the weather. Fewer delays on framing can shorten the entire schedule.
What has not been shown yet is whether any of this lowers the price of a home. Neither company has released cost or labor savings figures, and the first Phoenix homes are not expected until 2027.
What it means for South Florida buyers
Nothing changes here tomorrow. This deal is limited to Arizona, and much of South Florida's new single-family construction uses concrete block walls, at least on the first floor, along with strict wind-load rules for hurricanes. Factory-built wood framing would have to work within those requirements before it shows up in a Port St. Lucie or Palm Beach County subdivision.
Still, it is worth watching. D.R. Horton builds in Florida, and if the Phoenix pilot shortens build times, other markets will follow. For buyers, faster and more predictable construction means firmer move-in dates and less time paying rent while you wait for your new home.
Whichever way a home is framed, the basics of buying new construction stay the same. Get your own independent inspection at each stage, read the builder's warranty carefully, and understand what the base price includes before you sign.
