In 1695, Elector Friedrich III of Brandenburg, the future King Friedrich I in Prussia, gifted the village of Lietzow to his wife of twelve years née Princess Sophie Charlotte of Hanover after she had returned her country house Schloss Caputh to him the previous year. A year later, Sophie Charlotte commissioned Johann Arnold Nering to draw up plans for a summer residence. As Nering died soon after, Martin Grünberg took over the realisation of the plans, which were later completed by Andreas Schlüter. At the time known as "Lietzenburg", the palace consisted of only one wing with two and a half storeys. The inauguration of Schloss Lietzenburg was celebrated on July 11, 1699, the 42nd birthday of Elector Friedrich III. He, however, did not spent much time at the palace as it was his wife's property and their marriage not one full of love.
Two years after the inauguration of Lietzenburg palace, Elector Friedrich crowned himself King in Prussia and Sophie Charlotte became his Queen. Architect Johann Friedrich Eosander von Göthe was soon commissioned to extend the Schloss to represent the couple's new status. And so two side wings were added to enclose a large courtyard and the main palace was extended on both sides.
