[3] Heussler is believed to have built his home Fernberg on that land in 1865, giving it a name of German origin that meant "distant mountain".

The design of the house is attributed to Benjamin Backhouse, an architect responsible for several substantial commissions in Queensland, New South Wales and Victoria.

Local examples of his work include other villa residences such as Baroona, Cintra House, Riversleigh (on North Quay) for Edward Tufnell and Old Bishopsbourne.

The roof is covered with slates, the verandahs and balconies being spacious, and presenting a delightful retreat for the enjoyment of pure air, shade and widespread and charming view.

The grounds are all enclosed, the timber having been thinned so to give the place a park-like appearance, and there is a shrubbery and garden around the house.

[3] John Heussler died on Saturday 26 October 1907 at his home Unthank at Christian Street, Albion (now Clayfield).
