Curved walls and arches are returning to Australian homes, bringing softness and flow back into interior spaces. Where once straight lines and sharp corners dominated, curves now offer a more elegant and organic feel that’s also visually striking. From arched doorways to sculpted bulkheads, these shapes are being used to add character and depth to otherwise simple layouts. Thanks to flexible plasterboard, these elegant features are now quicker and more cost-effective to build without the bulk or cost of traditional masonry or solid plaster. Read on to discover why curved walls are trending again and how you can bring them into your renovation.
Why Curved Walls are Trending Again

Curved interiors are resonating with more than just design lovers. They’re shaping how spaces feel. Soft, rounded forms bring a sense of calm and flow that sharp corners lack. In busy urban homes, curves introduce a more welcoming and restful vibe that balances out harsh lighting, modern finishes, and boxy floor plans.
The resurgence of curves is influenced by Mediterranean and Art Deco aesthetics, but it’s also being reimagined in contemporary design. Arched corridors, circular niches, and sculpted bulkheads are statement features that help define zones in open layouts or draw the eye in simple places. Whether you’re renovating a terrace in the Inner West or upgrading a modern home in the Hills District, curves add a touch of luxury without overpowering the space.
What is Flexible Plasterboard?
Flexible plasterboard is a lightweight material designed specifically for creating curved walls, bulkheads, and design features. It’s typically 6 mm thick, which allows it to bend smoothly around tight radii without cracking or breaking. This makes it ideal in modern home renovations where curves are part of the design vision.
Products like Gyprock Flexible and Siniat CurveShield are some of the most commonly used options. These boards are installed over a curved frame and then set, sanded, and finished just like standard plasterboard. Compared to timber cladding or traditional masonry or solid plastering methods, flexible plasterboard is faster to install, less messy, and significantly cheaper as a result. The result is a smooth, modern finish that looks high-end but is easy to build.
Where to Use Curves in Home Renovations

Curved walls can be both functional and decorative, adding a unique flow to everyday spaces. Whether you’re renovating a period home or updating a newer build, there are plenty of ways to work curves into your layout. Here are some popular ideas:
- Arched hallway entrances and doorways. These instantly elevate transitional spaces, adding a soft, classic touch that feels welcoming and intentional. Perfect for older homes or new builds with character.
- Curved feature walls in living or dining areas. A gentle curve can turn a plain wall into a standout design feature. It draws the eye, helps define open-plan zones, and adds depth without needing loud colours or textures.
- Rounded bulkheads or ceiling transitions. Curved ceiling details create a smooth flow between rooms and can be used to conceal lighting, ductwork, or changes in ceiling height in a more elegant way. Different bulkhead designs can suit the room’s layout, ceiling height, or overall style of the space.
- Curved stairwell walls or balustrades. Instead of boxed-in stairs, a curved wall can give your staircase a sculptural feel. It adds movement and softness to what’s often a rigid architectural element.
- Bathroom niches or curved walls in showers. In bathrooms, curves add visual interest and can create spa-like enclosures that feel more open.
- Curved walls in home theatres or media rooms. Soft curves can help improve how sound moves through a space. It’s a smart way to blend form and function in rooms designed for immersion, and a great addition for improving home theatre acoustics without compromising on style.
Ideal for Sydney Renovations

Curved walls are a clever way to elevate Sydney homes of all shapes and sizes. From character-filled terraces in the Inner West to the modern builds in the Northern Beaches, curves help soften rigid layouts and add a custom, high-end feel without blowing the budget.
Many Sydney homeowners are looking for ways to make their interiors feel more unique and considered. Curves can be a standout feature that adds personality without needing major structural changes. And when handled by a professional, the result blends style with lasting quality that suits older properties and contemporary spaces alike.
Why a Specialist Plasterer Makes All the Difference
While flexible plasterboard makes curves more achievable, getting them to look smooth, symmetrical, and crack-free is a whole different story. Working with curves requires a level of precision and experience that goes beyond basic plastering. Even the smallest error in framing or joint setting can lead to visible seams, uneven curves, or future cracks.
A professional plasterer understands how to prepare the framework correctly, handle the delicate board without over-stressing it, and set the joint so that it blends seamlessly into the curve. Tools, timing, and technique all matter. Without the right skill, the result can look rough or unfinished, which defeats the purpose of adding a curve in the first place. If you’re investing in curved features, it’s worth working with a professional plasterer in Sydney who knows exactly how to bring them to life, from the first bend to the final sanding.
Add Value and Style With Curves
Curved walls have officially stepped back into the spotlight, and with modern materials like flexible plasterboard, it’s easier to bring this design trend into your home. Whether you’re after a soft statement piece or a full architectural feature, curves instantly elevate the way a space looks and feels.
The key is making sure they’re done right. A clean finish, smooth radius, and long-term durability all come down to expert installation. If you’re planning a home renovation, curved plasterboard can be included as part of your renovation plastering plans to help create a smooth, high-end finish.
