Granite Properties is a Plano, Texas-based real estate investment and development company, operating as a limited partnership (Granite Properties, LP), co-founded by Stacy Schusterman in 1991 and led by her as Chairman and CEO. The company specializes in the acquisition, development, leasing, and management of premium Class A office properties, with a primary focus on the Dallas-Fort Worth metropolitan area. It has developed major projects including the Granite Park campus, a 400-acre master-planned business community in Plano featuring high-end office towers, hotels, and retail spaces. Granite manages a portfolio of millions of square feet leased to Fortune 500 companies and other blue-chip tenants, emphasizing sustainable building practices and architectural excellence. Recognized as one of Texas's largest privately held commercial real estate firms, it benefits from the Schusterman family's extensive resources following the 2011 sale of Samson Resources to Berkshire Hathaway. The organization maintains a low public profile but has been involved in significant transactions, including property sales and joint ventures with institutional investors.
