The house has a palatial appearance and was built in the years 1791-1795. The design of the house is probably by the Aachen architect Joseph Moretti, who had previously built the Vaalsbroek castle and the Clermont house for the Von Clermonts. The original house was a wide building with a full basement, which was built in three layers above the cellars: a rez de chaussée (ground floor), above that the belle étage, a third floor and a high mansard roof that housed two attic floors. The building was built in the then popular Louis XVI style. It had a central riser on the front facade with a pediment on top, and a double landing staircase to the main entrance. The mansard attic was converted (at least before 1897) by the religious into a full-fledged fourth floor, with a single-storey attic.
More or less on the foundations of the demolished, former monastery wings, modern, slightly circular hotel wings were built on either side of the castle around 1991. No trace remains of the chapel.
