August Heinrich Andreae (4 December 1804, Garbsen – 6 January 1846, Hanover) was a German architect, painter, and etcher.

He first studied architecture with Diederich Christian Ludwig Witting [de] in Hanover.

[1] When he had gained some experience, he took and passed the state examination, and created several apartments in Hanover, which established his reputation.

In 1829, he succeeded Justus Gerhard Kahle (retired) as Hannover's Master Builder.

The building was heavily remodeled twice, in 1858 and 1933, and ultimately destroyed by an air raid during World War II.
