 Although the original plan was more modest in scope, involving light industrial buildings with a motor hotel along Tresser Blvd.and an open-air shopping promenade planned for East Main Street, the city and the redeveloper took advantage of an opportunity to capitalize on corporate moves out of NYC.Although One Landmark Square was completed in 1972, a 300,00 SF office building which for 37 years was the city's tallest, it was the completion of the GTE World Headquarters in 1973 that became the catalyst for downtown office development, setting an example for other corporations seeking a less expensive labor pool, a more favorable income tax structure and lower operating costs.
