He made early trips in France and Italy where he studied the new baroque forms of architecture.
In 1646, he received a royal scholarship for three years and began an international trip to study architecture.
For Magnus Gabriel de la Gardie he planned the remodeling of the Karlberg Castle in the capital.
Other notable examples of his work are the castle of Skokloster, the Palace of Bonde (now the seat of the Supreme Court) and the remodeling of the Wrangel Palace (now the seat of Svea Hovrätt, the Svea Court of Appeal), both on Riddarholmen in central Stockholm.
His daughter, Margaret de la Vallée, was married to architect and master builder Mathias Spieler (c. 1640–1691).
