Historic Windsor Lab Getting Major Expansion, Upgrade

WINDSOR, CT — A major renovation and expansion project is getting underway at the Connecticut Agricultural Experiment Station’s Valley Laboratory in Windsor.

Gov. Ned Lamont joined state officials, scientists and labor partners Tuesday for a groundbreaking ceremony at the site. Officials said the work will modernize the facility and expand space for research tied to plant diseases, insect pests and soil health.

The project includes renovations to the historic Valley Laboratory building along with construction of a new three-story addition. In total, about 24,800 square feet of laboratory and support space will be added to the existing facilities.

Plans also call for modular greenhouses, utility upgrades and other site improvements. A geothermal well field will also be installed to provide energy-efficient heating and cooling.

The Valley Laboratory provides research and diagnostic services for commercial growers, municipalities and homeowners across Connecticut. That work includes identifying plant diseases and insect pests, improving soil health and supporting sustainable crop production and landscape management.

Connecticut Agricultural Experiment Station Director Dr. Jason C. White said the project will give scientists the modern labs and infrastructure they need to keep delivering those services. He said the agency’s work supports farmers, growers, municipalities and residents across the state.

The project is being administered by the Connecticut Department of Administrative Services. DAS Commissioner Michelle Gilman said the work is also an investment in public research infrastructure and the state’s long-term climate goals.

She said the project will combine historic preservation with modern research space and energy-efficient design. Gilman said features such as the geothermal system and high-performance building standards are intended to reduce environmental impact while supporting scientific work.

Construction is expected to reach substantial completion by August 2027. When finished, officials said the upgraded Windsor facility will better position the station to respond to agricultural and environmental challenges facing Connecticut.
