The Tech campus, which covers approximately six acres, was built in several construction projects. The first three-story section was completed in January of 1917 on the corner of 12th Avenue and 7th Street. In 1938, the size of the school was nearly doubled with the addition of the second three-story section to the north. Clark Field, named for Miss Elizabeth Clark, the first principal of Tech, was constructed in 1942. In 1954, the H.B. Gough addition, named for Harry B. Gough, superintendent of Schools from 1930 to 1958, was completed to the north along 12th Avenue. The first two floors of the west wing across 13th Avenue were completed in 1963, and the third floor was added in 1965. Finally, the athletic wing, which houses the gymnasium and swimming pool, was completed in 1975.

Although Tech has grown to a complex encompassing over 550,000 square feet of floor space, it is more than just bricks and mortar. Tech is a total learning experience. The friends you make and the experiences you have here will remain a memory with you for your entire lifetime.
