As an architect at the gas and electricity plants, Gustaf de Frumerie worked under fellow Swedish architect Ferdinand Boberg, who was hired by the city to design the new large technical facilities for gas and electricity production, which were built around the turn of the 20th century.[2] Gustaf de Frumerie became known thanks to the building of some large office and industrial facilities for Stockholm's gas, electricity and waterworks, where the chief architect was Boberg, whom he later succeeded in this capacity.
Among his works is the building for Stockholm's water pipeline and Stockholm's gasworks on Torsgatan [sv] (Stockholm), which he designed together with Boberg. The building was inaugurated in 1906. Today, Stockholm Water [sv] has its premises there.
In the years 1910 to 1920, de Frumerie was responsible for the expansion of Värtaverket [sv] in Stockholm and in 1929 for the extension of Kronobergsstationen on Kronobergsgatan [sv] (Stockholm). In 1913, he was the architect of Lillsjöstationen [sv] in Ulvsunda, whose facades he designed in a brick architecture with national romantic elements.[3] In 1926 he designed Högalidsstationen on Krukmakargatan [sv] (now demolished). The facility is characterized by powerful building volumes and design with classicist form elements.[4]
He was the architect of the Untraverket [sv] at Dalälven in northern Uppland, which was inaugurated in 1918 and was the first hydropower plant to supply electricity to Stockholm. Gustaf de Frumerie also designed poles for arc lamps at Norrbro and Norrmalmstorg.[5] Norrmalmstorg's golden Art Nouveau-inspired luminaires on high poles were erected in 1911 and taken down in connection with a rebuilding in 1967 for right-hand traffic. In 1994, they were put back into place. They were, in fact, copies made after Frumerie's preserved drawings, as the original luminaires were lost.[6] In the 1920s, he developed the prototype into a lamppost with a curved upper part.[7]
