Sydney Opera House
The cost of the project so far, even in October 1966, was still only $22.9 million, less than a quarter of the final $102 million cost. However, the projected costs for the design were at this stage much more significant.
Babworth House
The estimated cost of the work was from A£30,00040,000. The house was on a grand scale with high quality finishes and it appears that it was not until 1915 that Samuel Hordern and his family took up residence in their new home, called Babworth House. Its style and location were sure marks of a class of commercial entrepreneurs which had established itself as part of the Sydney social elite.
