His father was also an architect, and moved in 1804 to Munich, where young Gärtner received his first education in architecture. To complete that education, he went in 1812 to Paris, where he studied under Percier, and in 1814 to Italy, where he spent four years in the earnest study of antiquities. The fruits of this labor appeared in 1819 in some views accompanied by descriptions of the principal monuments of Sicily (Ansichten der am meisten erhaltenen Monumente Siciliens).
After a visit to England, Gärtner was appointed, in 1820, professor of architecture in the Academy of Munich. His work as a practical architect began with this appointment. In 1822 Friedrich von Gärtner was appointed artistic director of the Nymphenburg Porcelain Manufactory. Gärtner eventually became head government surveyor of buildings and from 1842 director of the Academy of Fine Arts in Munich.
