Why limit your trim to just one spot? Our door frame additions can wrap neatly around windows, and they’re just as stunning on cupboard surrounds and built-in robes common across Perth.

Plain cornices cover the gap where the wall meets the ceiling. That's it.

Decorative ones pull your eye upward, so the ceiling reads higher than it actually is.

Most people assume switching means tearing the old ones out. It doesn't. Ours fit onto your existing cornices, and they're made from polyurethane making them lightweight and perfect for a weekend DIY project.

Want to upgrade your plain cornice?

Removing cornice can be a daunting and tricky task, as the ceilings can get damaged in the process, and cause additional and unecessary expense.

We have been asked if our cornice profiles fit right over the entire existing cornice and the simple answer is 'no'. To be able to cover the entire depth of the existing cornice will require a very large profile which is fine if you have high ceilings, but if you don't, there lies another problem 🤔 as it can suffocate the room making it look a lot smaller than it really is.

But this isn't a problem with our 'Easy Cornice' as they fit onto the edge of the existing cornice at the top (on the ceiling) and on the bottom (on the wall). No large, intrusive profiles dragging the room in, no risk of damaging the ceiling, and with a range of profiles to suit every taste, jazzing up your plain cornice has never been easier.

Door frame additions that do more than doors! ✅
We designed these to sit perfectly on door frames, but they also look fantastic on any edge with a rebate, like these window shutters 🏡✨

Plain white cornice? Most Perth homes have one, courtesy of the cookie-cutter builds that went up during the boom.

You don't have to rip it out to change it. Our cornice additions have a rebated edge that sits straight onto what's already there.

They cover the cracking too. Permanently 😉

Are You Settling for Plain Cornices? - Authentic Additions Unfortunately, many people settle for plain cornices, unaware of the transformative power these decorative accents can bring.

Installing Gyprock or Plasterboard Walls - Authentic Additions 18/09/2026

Installing Gyprock or plasterboard might seem simple, but a rough or incorrect installation can lead to ongoing cracks, visible joins and extra maintenance down the track.

For a clean, professional finish, the boards need to be installed properly, secured correctly, flushed tightly and sanded once dry. It’s the kind of detail that makes all the difference once the wall is painted.

At Authentic Additions, we’ve seen plenty of DIY 🛠️ mishaps over the years. Read our blog for some tips on how to get a professional finish.

If you’re unsure about any part of your wall installation, getting professionals like us, involved can save you time, stress and costly repairs later.

Installing Gyprock or Plasterboard Walls - Authentic Additions Installing Gyprock or plasterboard on walls may look an easy task, but we can assure you that it’s not that simple.

Not all homes (or ceilings) are the same and that’s why our cornice mouldings come in multiple sizes.
Whether you want a subtle refresh or a more ornate finish, Andy designed them so that you can attach them to the top and bottom of your existing plain cornice or just one side for a tailored look. 🛠️📐
The right choice depends on how ornate your home is and the height of your ceilings. If you ever need any guidance, we're always happy to help!

In an industry that hasn't always got the strongest reputation, and where competition is fierce, especially when it comes to pricing, we have stayed 100% true to ourselves, our principles and our work ethic.

We are so grateful when customers take the time to offer us feedback, and this recent one is no exception.
Thanks and with gratitude 🙏

Need to separate a large room, create a study nook, divide an office space or make better use of an open area?

Gyprock and plasterboard walls are a practical way to create new spaces, but the framework and finish need to be done properly to avoid cracks, movement and uneven joins later.

At Authentic Additions, we install our own stud/framework before attaching the Gyprock plasterboard, helping the job run smoothly from start to finish. Get in touch today about your next project and we'll be happy to help!
