Van Campen was selective in what projects he took on. His best known works are:
As well as houses and palaces, he also designed a number of churches, such as those at Renswoude and at Hooge Zwaluwe, and the Nieuwe Kerk in Haarlem. Of that design, Pieter Saenredam made no fewer than three paintings and eight engravings. Furthermore, Van Campen designed gates and towers, e.g. for the Westerkerk and Nieuwe Kerk, both in Amsterdam. His paintings and wall decorations (such as those at Paleis Huis ten Bosch), show some similarity with the work of Paulus Bor, one of the founders of a group of painters calling themselves the Bentvueghels).
