Filigree architecture

Filigree architecture is a modern term given to a phase in the history of Australian architecture. The phase was an embellishment of the "Australian verandah tradition", where the verandah evolved from its functional usages to become highly ornamental.

The filigree style was a vernacular tradition of buildings possessing prominent verandahs that screened the facade, cloaking the exterior in an ornamental veil that obscured the rest of building. On filigree style buildings, the verandah was the dominant visual element. The term "filigree" refers to the intricate texture of this verandah screen, which was often perforated to let air and light pass through, creating dazzling displays of shadows.

In the Victorian era, the style exploded into popularity. Double- and triple-storey verandahs lined the main streets, with some rare examples reaching up to four storeys. Victorian Filigree style verandahs were made almost exclusively from cast iron, and their delicate appearance gave rise to the term cast iron lacework. In the Federation era, the style evolved into the Federation Filigree style, when timber eclipsed cast iron as the predominant material of choice and the shape and form of the verandah became more novel.

The style was mainly popularised by speculative builders, but it did not have a class consciousness, being used both on humble workers cottage developments and grand mansions, as well as by prominent commercial architects such as Richard Gailey and Andrea Stombuco. Neither was it reserved for a single setting, being used on domestic, commercial and governmental buildings, becoming particularly well associated with Australian terrace houses and pub verandahs.

These strong associations have led to the filigree style being "regarded as distinctly Australian." While ornamental cast iron verandahs can be found elsewhere in the world, Australia possesses a unique interpretation of the design and form of this style, as well as a prevalence unseen elsewhere.
