Ernst Carl Westman (February 20, 1866 - January 23, 1936) was a Swedish architect and interior designer. He was an early adopter of the National Romantic Style, but turned later to the neo-classical style of the 1920s.
Carl Westman was born in Uppsala in 1866. He studied at the Royal Institute of Technology in 1885-1889, and then at the Royal Swedish Academy of Arts in 1889-1892, in Stockholm. In 1893 he married artist Elin Andersson and moved to the United States where he practiced with architect R. L. Daus in New York City in 1893-1895.
In 1895, he returned to Stockholm to work for architect Aron Johansson (who at that time was the architect working with the new Parliament building (1895-1904) in Stockholm). In 1897, Westman opened his own architect bureau. He became a member of the Royal Swedish Academy of Arts in 1912 and in 1916 he became the chief architect of the Swedish Royal Medical Board.
Carl Westman was one of the foremost advocators in Sweden for a return to the national characteristics in architecture. He was one of the first Swedish architects who developed the new Nordic National Romantic Style, a style which took the cultural and building precedents and merged them with ideas from the English Arts and Crafts movement to create a very distinct Swedish architecture often in brick and wood.
Carl Westman's Swedish General Medical Association building in Stockholm (1904-1906) was the first building built in the National Romantic Style, with the Röhss Museum in Gothenburg (1910-1914) and (1911-1915), providing another two prominent examples. The Stockholm Courthouse has striking similarities with the medieval Vadstena Castle, and provides a dazzling sight in downtown Stockholm, though the building proves quite inflexible for its purposes.
