The Cornerstone Company is a commercial general contractor and land development company who employs the design-build process to offer customers a superior product that exceeds expectations. Founded in 2003 by President Terry Weeks, a graduate of the Construction Science and Management (CSM) program at Clemson University and an experienced manager of commercial and light industrial projects totaling over $45 million and including the Columbia Museum of Art, the Cassique Clubhouse on Kiawah and International Center I and II at the Charleston Regional Business Center, the company specializes in retail, office, medical, light industrial and church projects. By using the design-build construction process, with the engineers, architect and general contractor all on one team, Cornerstone is able to best meet the needs of its clients by eliminating many of the hassles associated with traditional building methods. The design-build process helps shorten project duration, reduce costs, improve communication and prevent contractor-architect disputes. In addition, The Cornerstone Company is actively involved in land procurement and development and can also assist clients who want or need to lease buildings or space. We provide complete build-to-suit services and on some properties give tenants the option to buy.
