The building was based on the contemporary architecture of Dutch classicism in its external form, with its vertical orientation and the turrets on the side wings.
From 1689, the Electress' son, Frederick I, who loved splendour, had the palace and gardens enlarged, influenced by Italian and French baroque architecture.
He changed the facade of the corps de logis and added two north rear wings with final pavilions, connected by a walk-in arcade, and thus a second courtyard.
His son Frederick William I only lodged occasionally in Oranienburg, and just the most necessary funds were granted for the maintenance of the palace.
His son Frederick II transferred the estate to his younger brother Prince Augustus William of Prussia on the occasion of his marriage in 1742.
