BALTIMORE — Blueprint Robotics, a Baltimore-based company that produces wood-frame construction products is planning to build a 450,000-square-foot production facility in Windsor, Connecticut, that is said to be the largest North American industrial building erected entirely of mass timber.

The 62-acre lot on Day Hill Road in Windsor selected by Blueprint is currently vacant. It is expected the facility will cost $97 million to design and construct. The company hopes to break ground in June or July and have the construction finished in the third quarter of 2024, according to Blueprint CEO Jerome D. Smalley.

Once the plant is functional, it will fabricate mass timber components and large-scale cross-laminated timber, which reportedly is the first CLT product by the company.

Blueprint produces wood-based products for multifamily housing developments, including apartments and senior living facilities, and then delivers and installs them at the construction site. It emphasizes green building techniques, including carbon sequestration.

“We don’t produce lumber. We produce the building,” Smalley told the Hartford Business Journal. “We use lumber as our medium. We produce the structural system, the framing system, and the mechanical systems — electrical, plumbing, and fire protection systems — for an apartment building. We produce them and then we ship them to the job site and install them on our customer’s foundation.”

Smalley said the Baltimore facility is operating at full capacity, prompting the company to look at expansion options.

“The Baltimore plant has been quite successful,” Smalley said. “We are seeing increasing demand for our product and looked to the Northeast United States for a location to build a second plant. After a site search, we came upon the site that we’ve identified.”
