A local newspaper, "The Bacchus Marsh Express" of Saturday 14 October 1876 on page 2 stated that "here we may say that the contractor for the building — Mr. P. Colquhoun — has been the chief designer, assisted by Mr. Fox, architect, and by the Messrs. Chirnside themselves."

"The Bacchus Marsh Express" of Saturday 7 July 1877 on page 3 stated that "Mr. Huckson .... has had a good deal of the management of Mr. Chirnside's new house".

[6] The Melbourne newspaper "The Age" of Saturday 15 Dec 1877 on page 5 stated "There is on exhibition, in the window of Mr. W. R; Stevens, 78 Swanston-street, a picture, which is indicative of the immense fortunes made by some of those who have been lucky or clever enough to aggregate large treats of land in this colony.

It is a representation of a mansion erected by Messrs. T. and A. Chirnside on their estate at Werribee Park, which appears to be one of the finest buildings of the kind in Victoria.

The building was commenced between three and four years ago, and was designed by Mr. James H. Fox, architect, of this city, who has also had the superintendence of the works.

The design is of the modern classic style, and reflects great credit on the architect, whose name is well known in connection with several other large houses, notably that of the late Mr. John Moffatt, at Chatsworth, in the Western district."

Rooms in the house were used for American-based film The Pirate Movie, starring Kristy McNichol and Christopher Atkins.

In December 2007, the Werribee Park Mansion hosted two Elton John concerts as part of his Rocket Man Solo Tour.

It was renowned for its peaches, grapes, apples, quinces, pears, a variety of plums and several other fruits, as well as walnuts and olives.
