Soon becoming an associate in Fles's firm, he created several sculptures in gypsum for the Military Hospital in Bucharest.

[5] That same year co-founded a German-oriented cultural society in Bucharest,[5] and designed and executed two akroteria for the faç of the National Theatre; the theater was damaged beyond repair in the Luftwaffe bombardment of Bucharest on August 24, 1944 (see Bombing of Bucharest in World War II),[6][7] but the akroteria survive in the collection of the Frederic and Cecilia Cuțescu-Storck Art Museum[5] ("the Storck Museum").

[5] Besides creating a variety of sculptural elements for several churches,[8] Storck designed and, with his team (most notably, Paul Focșeneanu [ro][5]), sculpted the pediment for the main building of the University of Bucharest (1862),[8][5] damaged beyond repair in the Allied air strikes of April 4, 1944, during World War II.

[14] The most notable of the seven who survived was Frederic Storck (1872-1942), who would go on to be one of the leading Romanian sculptors of the first half of the 20th century, and who would marry Cecilia Cuțescu-Storck, a prominent artist who became Europe's first female art professor.

In 1866, after a brief period of political turbulence, Romania became a kingdom under the Hohenzollern monarch Carol I. Storck's career continued apace.

al. say was the first factory to make terracotta tiles specifically for façades of houses,[16] sold four years later to Anton Weigand.

[14] The most notable of these, a sculpture in Carrara marble at the hospital now known as Spitalul Clinic Colțea [ro], was later lost—literally—during the widening of Bulevardul Ion C.

[14] After another period of travel and study in Vienna and Florence, he returned to Bucharest, and in 1871 executed the double stairway in Carrara marble in the garden of the Stirbey Palace [ro] in Buftea, 20 kilometres (12 mi) from Bucharest; he executed this project in conjunction with a team from the atelier of Italian sculptor Filippo Grossi.

For most of these, he executed the original versions (typically in gypsum) but the monumental marble versions would be completed—some after his death—by his son Carol and by Carl Teutsch: the massive Carrara marble statue of Domnița Bălașa [ro] (commissioned 1881;[14] unknown date of completion; the current marble statue is a reproduction dating only from 1992); the statue of Ana Davila [ro] (commissioned 1882,[17] completed 1890); the staircase of honor, columns, and the balustrade of the balcony of the Romanian Athenaeum (commissioned 1883,[17] completed 1888); the statue of Protopopul Teodor Economu [ro] (commissioned 1884[17]); and the staircase of honor leading to the throne room of the Royal Palace (commissioned 1885;[17] the Royal Palace from that era does not survive[18]).
