Berend Tobia Boeyinga was born in 1886 in Noord-Scharwoude as the son of a reformed ('Gereformeerd') minister. Originally his name was spelled Boeijinga. After having worked as a carpenter he moved to Amsterdam in 1909 where he studied to become an architect. During this period he worked as an overseer for the offices of Eduard Cuypers, Charles Estourgie and Michel de Klerk. He graduated in 1919 with a design for a new parliamentary building. In 1921 he became an architect for the Amsterdam municipality; in this function he became involved in several large housing projects. This rather anonymous way of working didn't satisfy him, and after having participated in several competitions he left his function in 1926 to become an independent architect.
Although a versatile architect, Boeyinga is especially important for his churches in Expressionist style; he was one of only a few architects of the Amsterdam School who designed churches. In Boeyinga's case in first instance for the Gereformeerden for whom he built 15, plus three for the Hervormden. In 1926 a conflict in the church over the interpretation of the history of creation made him leave his denomination, after which he joined another one in 1930 which in 1946 merged with the Hervormden. Shortly before he died he returned to his old church.
Boeyinga's religious architecture was greatly influenced by his faith. He was a great admiror of leader of the Gereformeerden movement Abraham Kuyper and his ideas about art and architecture. More than any other architect of this denomination has Boeyinga tried to design optimal centralized churches. After having designed in Expressionist style for many years in the late 1930's he experimented with other styles as well. After World War Two he restored several churches as well as building several new ones.
