Robotic home-builder Reframe Systems, a company founded by former Amazon Robotics executives, will use a new $40m tranche of equity financing to build a second automated component factory in Massachusetts.
Inside the factory, robotic arms build panels and modules guided by software to automate repetitive steps like measuring, cutting, fastening and material handling.
The components are then transported to the prepared site where field teams assemble them and complete the connections and finishes.
The company calls it a “microfactory” because the idea is to make them mobile and easy to set up near a house-building site in a spare, empty building.
Reframe Systems’ chief executive Vikas Enti told GCR that a microfactory can be set up in an existing 50,000-70,000-sq-ft building in around 100 days and be equipped for less than $5m.
The company claims its system can build homes three times faster and 35% cheaper than traditional methods.
Enti said the system can work with more traditional construction techniques based on what each project requires.
“The goal is to augment the entire construction process, making it more predictable and efficient while building on the methods and expertise that already work,” he said.
“Our software incorporates local zoning, terrain, climate and architectural requirements, then automatically generates the production files and field instructions used to build each home.”
New factory to replace the first
So far, Reframe has one operational microfactory, FAB0 in Andover, also in Massachusetts. The new one, FAB1 in Billerica, will replace FAB0 when it starts operating in October.
FAB1 is designed to produce up to 500 multifamily units or 250 single-family homes a year.
Reframe has completed 10 homes so far and aims to complete 114 by the close of 2026.
One of the new homes is a wildfire-resilient bungalow and accessory dwelling unit in Altadena, California, for a family who lost their house in the wildfires of January 2025.
Its owners Jonathan and Marisol Talbot said: “After the fires, we were being told that a traditional construction rebuild could take years and could cost far more than we could afford. Reframe streamlined the process, secured the permits, coordinated with a contractor, and is completing our new wildfire-resilient home in months at a cost that worked for our family.”
