WESTMINSTER, MD. — Construction has begun on a 30,000-square-foot building within Carroll County Commerce Center, a 32-acre business community located at the intersection of Interstate 97 and Maryland Route 140 in Westminster. The single-story facility is slated for completion this fall, and will feature spaces starting at 2,100 square feet. Tenants within the larger 96,000-square-foot business park, which will be expanded to total approximately 200,000 square feet of office, warehouse and industrial space by the end of the project, already include the Carroll County Chamber of Commerce, the U.S. Department of Agriculture and Carleton Technologies. After completion of the latest phase, three additional buildings, including a two-story office project are planned. Robert Rosen, acting as owner and developer, has selected Townson, MD.-based NAI KLNB to handle leasing activities for the park.
