Concurrently with the onset of the industrial revolution, the [[Swiss Federation]] planned to establish a [[Institute of technology|polytechnical]] school. As the principal judge for the [[architectural design competition|competition]] held to select a design for the new building, Semper deemed the submitted entries unsatisfactory and, ultimately, designed the building himself. Proudly situated (where fortified walls once stood), visible from all sides on a terrace overlooking the core of [[Zürich]], the new school became a symbol of a new epoch. The building (1853–1864), which despite frequent remodeling continues to evoke Semper's concept, was initially required to accommodate not only the new school (known today as the [[ETH Zurich]]), but the existing [[University of Zurich]], as well.

In 1855, Semper became a professor of architecture at the new school and the success of many of his students who attained success and renown served to ensure his legacy. The Swiss architect [[Emil Schmid]] was one such student. With his income as a professor, Semper was able to reunite his family, bringing them to Zürich from Saxony. The City Hall in [[Winterthur]] is among other buildings designed by Semper in Switzerland.

In 1861, Semper and his family were awarded Swiss citizenship by the Swiss municipality of [[Affoltern am Albis]] in return for the planning and construction of their main church's bell-tower.<ref>{{cite web |last1=Bussmann |first1=Monica |title=Wie Gottfried Semper Schweizer wurde |url=https://etheritage.ethz.ch/2016/09/02/wie-gottfried-semper-schweizer-wurde/ |website=In: ETHeritage.

Semper provided [[Bavaria]]'s [[King Ludwig II]] with a conceptual design for a theatre dedicated to the work of [[Richard Wagner]] to be built in Munich. The project, developed from 1864 to 1866, was never realized, although Wagner 'borrowed' many of its features for his own later theatre at [[Bayreuth]].
