Terra CO2, a technology company developing a low-carbon cement, has broken ground on a new headquarters and advanced materials testing and R&D facility at 1341 Avery St. in Golden.
The project officially broke ground in June, according to Terra. The 30,167-square-foot facility will consolidate and expand the company’s Golden operations, providing additional office space, an expanded materials laboratory and space for up to three pilot plants. Terra currently operates a single pilot plant.
The project is being developed by Terra CO2, with Intergroup Architects serving as the architect.
The facility is expected to significantly expand Terra’s R&D capabilities. Terra said its queue of candidate customer feedstocks has at times grown to as much as 12 months, driving the need for additional pilot capacity.
The building will also serve as a demonstration of Terra’s low-carbon concrete technology. A significant portion of the concrete will incorporate Terra’s proprietary OPUS SCM™, a supplementary cementitious material designed to replace a portion of traditional Portland cement. Eagle Materials, a major investor in Terra, will supply the concrete from one of its local ready-mix plants.
Terra expects concrete pours to begin in August, with completion anticipated in the first quarter of 2027. The company says the project will be the first building in the Denver metro area constructed with low-carbon concrete utilizing its OPUS SCM™.
Terra previously announced plans for the Golden headquarters in May, when it said the facility would include advanced materials-testing laboratories and expanded pilot-scale R&D facilities. At the time, the company estimated the building at approximately 32,000 square feet.
The project represents an investment of more than $7 million in Terra’s Golden operations, according to a 2025 letter the company submitted to the City of Golden Economic Development Commission.
The company also continues to advance its footprint with the retention of a $52.6 million grant award from the U.S. Department of Energy’s Office of Critical Minerals and Energy Innovation, supporting the planned deployment of a facility in the greater Salt Lake market.
