 Developers eventually bought the lots that composed Mount Osmond but once again interest in the suburb was minor . Attempts to bring in settlers culminated in the construction of Mount Osmond Road in 1882 . It wound around the hills from where it began as an offshoot of Mount Barker Road in the South . Developers broke down the three large lots into roughly two hundred 1 @-@ acre ( 4 @,@ 000 m2 ) ones in the hope of sales . A few lots were sold to quarrymen and gardeners around Mount Barker Road , but the vast remainder was leased to stockowners as pasture for their livestock . Much of Mount Osmond , along with a large portion of the surrounding area , was bought in 1907 by Ernest C. Sanders . His family made great use of the land , with his sons building houses on the vast property while raising sheep and growing hay . Considerable time was spent by the Sanders family in naming and mapping the area .
