With its opulent architecture and largely intact decoration, Labassa is one of Australia's most outstanding 19th century mansions.

The house as we see it today, reflects the work of architect John Augustus Bernard Koch who was employed by Cobb & Co. millionaire Alexander Robertson to create a lavish setting for grand social occasions.

In realising this ambition, Koch chose a design that brought together a French Renaissance (or Second Empire) style with Germanic and Hellenistic influences. For the interiors, the finest embossed wallpapers and mahogany timbers were used and a rare illusionist ceiling enhances the stairhall.

Externally the mansion features Corinthian columns, arcaded verandahs, classical decoration and inset Italian marble panels.
