Carmyle at 7 Carmyle Avenue, Toorak was erected in 1879 for prominent Scottish pastoralist, stock-agent and government land tax commissioner, Archibald Fisken. The 20 room two storey brick and stucco mansion, probably designed by noted Melbourne architect F M White in the conservative Italiante tradition was acquired by Colin Simson, a retired western district pastoralist in 1886. Carmyle at Toorak is a typical Melbourne mansion house styled in the popular conservative Italianate tradition of the 1870's and attributed to, characteristic of the work of improtant Victorian architect, F M White. The building is of local architectrual interest. Archibald Fisken, a noted pioneer pastoralist, stock agent and public identity built the mansion, but occupied it for only 7 years (1879-1886). Carmyle has been restored as a private mansion house and medical consulting rooms on a reduced site at Toorak. The building fabric is well maintained and appreciably intact externally, although enhanced internally. Of local significance.
