The structure was designed by Augustyn Wincenty Locci. The architecture of the palace is a unique example of different building traditions - reminiscent of Polish aristocratic mansions with side towers, the Italian suburban villa and French palaces entre cour et jardin with two oblong wings on each side of the cour d'honneur.During the first stage of construction, between 1677 and 1680 it was a typical Polish manor house with four alcove towers attached to the one-storeyed square building. Between 1681-1688, the building was enhanced and two gallery wings ending with towers were added. This new appearance was probably inspired by Palladio's Villa Montagnana. Shortly after the king's death the third stage of the reconstruction was accomplished. Between 1688-1696 the pavilion above the main building was erected and the towers were covered with baroque spires, all resembling the Villa Doria Pamphili in Rome (especially its initial design by Giovanni Francesco Grimaldi)
