If you're renovating or building in Australia and want to add architectural character to your facade, understanding keystones, corbels, and wall plaques is the starting point. This practical guide to decorative architectural mouldings in Australia covers what each product is, where it belongs, and how to narrow your choice for your home or project.
Homeowners, renovators, builders and designers across Australia need clear guidance when comparing architectural moulding profiles. This introduction covers the three product categories, then explains material, placement and selection considerations.
What Are Keystones, Corbels, and Wall Plaques?
Keystones, corbels and wall plaques each add a different type of decorative detail. The sections below explain where each profile is used and what visual role it can play.
Keystones
A keystone moulding sits above a window or door, framing the opening and drawing the eye upward. Originally, keystones locked the centre of a masonry arch in place.
Today, decorative exterior architectural mouldings like these are applied purely for visual effect, including on flat-headed openings where no arch exists. Whether your home features period joinery or contemporary windows, a well-chosen keystone adds visual emphasis and draws attention to the entrance. Browse our keystones collection to see the range of profiles available.
Corbels
Architectural corbels are decorative brackets applied under eaves, at gable peaks, or where a parapet meets a wall. They create shadow-line detail and a sense of visual support, without carrying any actual weight.
Corbels can define a transition beneath an eave, at a gable peak or beside a parapet. Compare the available profiles with the facade’s existing detail, whether your direction is traditional or contemporary. Browse our corbels to explore the profile options available.
Wall Plaques
Decorative wall plaques are standalone features for facades, garden walls, or feature walls. Unlike keystones and corbels, they are not tied to a window, door, or roofline.
They simply add character wherever a plain surface needs interest. A well-placed plaque can break up long expanses of blank brickwork, provide focal interest on gable ends, or add period detail to contemporary homes seeking character.

What Are These Architectural Mouldings Made From?
Exterior Mouldings keystones, corbels, and wall plaques are generally cast as reconstituted stone products, though exact material composition, finish, and suitability can vary significantly between individual profiles. Because dimensions, finish, and application details differ from one keystone, corbel, or wall plaque to the next, it is worth checking the individual product page or speaking with the Dandenong team before finalising a specification. This keeps material and performance claims specific to the product you are actually ordering, rather than assumed across the whole range.
Where Do These Architectural Mouldings Fit on Australian Facades?
Placement depends on the building's form and the effect you want to achieve. When you place architectural mouldings on an Australian facade, follow the building’s existing visual rhythm instead of adding detail at random. When installed thoughtfully, these decorative elements add visual cohesion and period authenticity to Australian homes.
Many older Australian homes lost their original detailing over the decades. Homeowners, who are restoring facades with architectural mouldings Australia, favour period keystones and corbels that bring back authentic character to Federation, Victorian, or Edwardian properties. Wall plaques offer a lighter-touch option where full restoration is not practical.
On a new build, keystones and corbels establish visual character from the start, whether classical or contemporary. Builders and designers sourcing architectural mouldings Australia, find profiles that suit everything from simple window keystones to detailed corbel brackets, reflecting the streetscape and design intent.
How Do You Choose the Right Profile?

Homeowners restoring facades with architectural mouldings Australia favour period keystones and corbels that bring back authentic character to Federation, Victorian, or Edwardian properties.
