David Adriaan Emaar was a Dutch architect in the Groningen town of Winsum. 

Emaar was on born on July 21, 1908 in Rilland-Bath. He trained as a carpenter at the trade school in Veendam. Immediately after the technical school, he learned the design trade in practice with the architects Evert Rozema (1892–1964) in Appingedam and Willem Reitsema (1885–1963) in Leens. Over time, he has gained practical experience in supervising works for municipalities such as Appingedam, Delfzijl and Hoogeveen. In the early period from 1928 to 1935 he works and draws for Rozema and Reitsema with the style characteristics of the Amsterdam School(in Groningen). In his work in the period around the Second World War, a modest influence of the Delft School is visible. From 1937 to 1957 he was municipal architect in the municipality of Winsum. In 1957 he chooses to continue as an independent architect. First in partnership with JG Deelman from Leek under the name of Architectenbureau Emaar en Deelman. From 1964 he continued the office alone, until his death in 1975.

In the 1960s he entered into a partnership with his colleagues H. Groefsema from Groningen, Barend Teunis Kleinenberg from Musselkanaal and JA van der Sluis from Gorredijk. They called themselves Werkgroep ECSC, the initials of their names in alphabetical order. This involves the development and application of synthetic facade components. The idea arose during a meeting of the Northern Contact Group of Private Architects chaired by JA van der Sluis. In Stadskanaal on De Weegbree (22–25) a row of houses was built as a prototype in 1967. The experiment was "a disappointing experience" for the group of architects.

He was a member of the Dutch Architects Society (NAG). His working area was mainly in the northwest of the province of Groningen: Winsum, Ezinge , Eenrum , Leens , Ulrum , Zoutkamp. 

Emaar died on December 27, 1975.
