Pyramid Packaging is making plans to move forward with the expansion of its current headquarters at 2901 Shermer Road, south of Willow Road. Company owner Bob Ploen says that he selected the Northbrook location in 2013 because the one acre lot was ideal should the growth of his business require more space. The two-part expansion will involve more than doubling the size of the current building to 13,500 square feet to accommodate continuing business growth. Ploen estimates the first phase of the project is expected to begin over the summer with the construction of a new 8,092 square foot building 12 feet south of the current building. In phase two, the company plans to move into the new structure, tear down its current building, and add another 5,440 square feet.
