The estate consists of a castle, an old granary renovated into a museum, a circular threshing machine, a neo-gothic chapel and the Jelačić family tomb.

During the process of disintegration of larger Susedgrad-Stubica seigniory, Novi dvori (Curia Nova), are mentioned as independent entity as early as the beginning of the 17th century.

[8] In the second half of the 18th century Peter Troilo Sermage turned the manor house into a castle and added several economic buildings such as barns, granaries and circular threshing machine to the estate.

Although the law of the Triune Kingdom of Croatia, formally obliged each candidate for the position of Ban, to possess its own estate on Croatian soil, this criterion was briefly ignored upon Jelačić's appointment due to the Revolutions of 1848.

This was subsequently commented by Jelačić using the following words: "I have always lived for my Homeland and everything I did, I did out of loyalty and fidelity, not for those 400 000 forints that I spent for buying the land estate in sense of our Constitution, which asks for Croatian ban to also be the landowner in our Kingdom.

The same year, on Christmas, Josip Jelačić's wife - countess Sofia, gave birth to their daughter Anica on the estate, for which occasion, the banner was raised on top of the manor.

[11] In 1919, countess Vera Jelačić donated the family collection of weapons and paintings from Novi dvori, to what was then Croatian People's Museum.
