Belasco also embraced existing theatre technology and sought to expand on it. Both of Belasco's New York theatres were built on the cutting edge of their era's technology. When Belasco took over the Republic Theatre he drilled a new basement level to accommodate his machinery; the Stuyvesant Theatre was specially constructed with enormous amounts of flyspace, hydraulics systems and lighting rigs. The basement of the Stuyvesant contained a working machine shop, where Belasco and his team experimented with lighting and other special effects. Many of the innovations developed in the Belasco shop were sold to other producers.
