 It is a rare, intact, and fine example of a suburban estate; its evolution over several stages (the earliest believed to date from the 1860s) well illustrating the development of Brisbane and one of its earliest suburbs, Hamilton.The place demonstrates rare, uncommon or endangered aspects of Queensland's cultural heritage.Arguably unique and indeed highly idiosyncratic Lochiel comprises a substantial house, outbuildings, and large established garden situated on the lower slopes of Toorak Hill overlooking the Brisbane River.
