The house at 45 Balac1ava Road, Caulfield North has architectural importance as an early example of the work of Edward F. Billson, whose work demonstrated the influence of the internationally distinguished American architect Frank Lloyd Wright and his one time colleague, Walter Burley Griffin with whom Billson worked in partnership for a period. It is presumed to be the earliest important example Billson's work and attains special importance as an early example of modern architecture in Australia, the earliest work of Griffin preceding it by only five years.
A large cruciform on plan house with attic storey in the Wrightian manner with dominant gables distinguished by their overhung eaves, increasing in depth top the ridge line and with vertical emphasis achieved by the use of protruding piers defining glazed sections. Windows have patterned glazing and louvred treatments characteristic of Wright's work and including opalesque panels, the entire composition developing characteristic geometric shapes. Masonry surfaces have a rough cast treatment; the roof has terra cotta tiles and the gutters are concealed giving emphasis to the fascias and barges.
