The marriage was a big change in Pontus' life; because he had married one of the richest heiresses in Gothenburg, he became a very rich man. He was able to leave his work as a wholesaler to spend the rest of his life in his greatest interest, the arts. Pontus and Göthilda decorated a beautiful home in Brunnsparken, in the center of Gothenburg, which would later be called the "Fürstenberg Palace". He started an art collection activity in his own house, with several million Swedish crowns as start capital. Thanks to Göthilda's enormous wealth, he could develop this activity with several promised artists.
