Short answer: on 13 October 2026 the Canadian company Promise Robotics announced a multi-year agreement with D.R. Horton, which it calls the largest homebuilder in the US by volume. Under the agreement D.R. Horton will use the Factory-as-a-Service model to produce more than 1,250 homes in the US. The robots and AI work in a factory that makes walls and floors, and these are brought to the site ready-made. The claims about speed are the company's own words. Below is what was announced, what remained unclear about the timing, and what to ask such a supplier if you build homes.

What was announced

There is one source: Eugene Demaitre's article in The Robot Report dated 13 October 2026. This is a retelling; I did not read the company's own page.

  • The agreement. Multi-year, with D.R. Horton, for producing more than 1,250 homes in the US. Promise Robotics calls D.R. Horton the largest American homebuilder by volume and the first major US homebuilder to use its platform.
  • What "Factory-as-a-Service" means. According to the company's description, a homebuilder gets access to production infrastructure without the cost, complexity and risk of building and operating it itself. The company operates in Toronto and was founded in 2021.
  • What is produced. Floor sections 45 feet long (about 13.7 metres) and walls 20 feet long (about 6.1 metres) with windows and doors, as well as stair cages that are dropped into place whole. The sweet spot, according to the founder, is townhomes of three or four storeys. For taller buildings, in his words, more sprinklers, bracing and metalwork are needed.
  • Speed. Attar said the company can build a two-family home with two storeys, a basement and a garage in one day, not counting electrical work, window installation and plumbing. He added that this process usually takes two to three weeks. The text does not make clear what that period refers to: the whole house or the work not included in the one day.
  • Where. The company is setting up its first Factory-as-a-Service facilities in Edmonton and Calgary in Canada and in Phoenix. The company runs the systems itself to get fast feedback.
  • How it works. The company's software reads existing home designs, produces production plans and instructions for the robots, runs the manufacturing and connects it with installation on site. According to Attar, it includes computer vision, large language models for the initial preparation of data flows, and a domain-specific reasoning model. At present the company works with its own cloud simulations and KUKA industrial robot arms, but is not tied to one robot maker.
  • Data. According to Attar, for every home built the company gets 300 new images and 5,000 new tactile data sources.
  • Codes. The fastening algorithms can be set to local building codes, for example for fastener spacing. Attar gave an example: in Phoenix 50 percent less sheathing and different bracing were needed than in the harsh conditions of Canada.
  • The customer's words. Brad Conlon of D.R. Horton said the company is always looking for innovations to speed up cycles, raise production capacity and bring more predictability.

What is not stated

The article has no price, payback period or information on how many homes have already been built under this model. There is no information on when deliveries to D.R. Horton start or on what share of the 1,250 homes the components cover and what share remains traditional construction. The speed claims are the company's own, and the article contains no independent verification.

Checks for a construction company

These are my suggestions, not data from the article. They apply to any supplier of ready-made walls, floor systems and modules.

  1. What the time frame includes. The phrase "in one day" without a list of work is misleading.
    • Who does it: the project manager together with your site foreman.
    • How to check: ask for a written list of what is done at the factory and what on site, and the time for each item. Add them up yourself.
  2. Compliance with your codes. Codes differ from region to region.
    • How to check: ask for a document in which the supplier shows how its construction meets the codes of your region, and have the designer responsible for your documentation read it.
  3. What happens if capacity runs short. According to the article, a homebuilder can buy as much capacity as it needs.
    • How to check: ask what the contract says about delivery times and about the supplier's penalty for delay.
  4. How the parts fit together on site. The finished walls must be set in the design position.
    • How to check: ask to be shown the dimensional tolerances and a trial assembly of one section before the contract is signed.

What this costs

The calculation uses conditional numbers; substitute your own. Suppose that checking the list of work and the timing takes a project manager 4 hours at 3000 roubles, a lawyer reads the contract for 3 hours at 4000 roubles, and a designer checks the codes for 6 hours at 2500 roubles. That is 4 × 3000 + 3 × 4000 + 6 × 2500 = 12,000 + 12,000 + 15,000 = 39,000 roubles once. Compare this with the cost of a week of idle crew time on site. If you do not know that cost, work it out before talking to the supplier.

When this does not concern you

If you do not build homes and do not supply the construction industry, the announcement does not directly affect you. If you are building a single house rather than a series, the article does not say whether such a model is available to you: it is described for a homebuilder with a large volume.

Summary

On 13 October 2026 Promise Robotics announced a multi-year agreement with D.R. Horton to produce components for more than 1,250 homes under the Factory-as-a-Service model. The claims about speed come from the company itself, the article has no independent verification, and the "in one day" figure does not include electrical work, windows and plumbing. A builder should request a written list of work with timings, check the codes of their region, agree on a penalty for delay and see a trial assembly.
