[1] Work commenced on Casa Grande as a home for the then General Manager of Mount Isa Mines, Julius Kruttschnitt II, in 1949.

It was a "grand house", designed by the prominent Brisbane firm of Donoghue, Cusick and Edwards, but reflecting the influence of Kruschnitt's time spent in both Arizona and Mexico.

[1] Kruttschnitt tackled Mount Isa's problems with relentless energy and after more capital was raised through overseas financiers, ore production commenced again in 1931.

Casa Grande was designed by the prominent Brisbane architectural firm of Donoghue, Cusick and Edwards, probably incorporating the ideas of their client, Julius Kruttschnitt.

In 1951 when badges were presented to employees of MIM who had served twenty years with the Company, a dinner was arranged for the 80 men and their wives by Mrs Kruttschnitt.

[1] Julius Kruttschnitt resigned as Chairman of Directors in 1952 but did not return to the United States, settling in Brisbane at his home Casa Ita.

[1] Casa Grande reflects the period in the life of Mount Isa Mines when the first dividend was paid, and the Company, after years of struggle, was becoming profitable.

The white walls contrast with the dark timber framed sash windows and doors, and the building has terracotta roof tiles and balconies.

[1] The large, U-shaped, two storeyed house, encloses a courtyard which is overlooked by surrounding verandahs supported by roughly hewn timber posts.

The encircling drive and luxuriant gardens, a striking feature in such an arid area, add considerable distinction and presence to the house, emphasising the social standing of the Chairman of Directors within the community.

Casa Grande, built on the original Mineside settlement, demonstrates the development of the Mount Isa as a mining industry town.

Casa Grande has a close association with MIM Directors, Julius Kruttschnitt and George Fisher, both of whom are men of international reputation.
