Ochiltree House, built in 1882, is one of the most flamboyant of all the mansions built in south-east Adelaide, and one of the many built for pastoralists. It has a Victorian Italianate look, but its most unusual feature is its mansard roof which reflects a French influence. Ochiltree was built in 1882 by G. Joachimi for the well known pastoralist John Rounsevell, who came to South Australia in 1839 with his family on the ship City of Adelaide.

Rounsevell was a pastoralist and founder of a coachline that plied routes throughout South Australia. He held title to many properties and land in the Hutt Street area, and was responsible for the construction of three large mansions in the south-east corner of the city that included Ochiltree House. His most notable venture was the purchase of the enormous Moolooloo Station in the Flinders Ranges and he held public office as Member for Light and Gumeracha.
