30th October 2025 Complete Guide to Curved Mouldings for Sophisticated Interiors Curves are leading the way in interior design. Their soft, organic forms bring comfort, flow, and calm to various interiors – from grand French Provincial aesthetics to minimalist, contemporary spaces. Yet beyond the furniture and lighting trends lies the unsung hero of graceful curvature: premium timber mouldings. Engineered for flexibility, curved timber mouldings in Australia — including curved architraves, concave mouldings, and curved skirting boards — are the perfect solution for elevating complex spaces. Whether framing dramatic archways, accenting feature windows, or enhancing curved staircases, custom curved skirting and architraves add both craftsmanship and continuity to any interior. At Intrim, we craft premium curved timber mouldings that blend form with function. In this guide, discover how curved mouldings can transform your design style — from timeless elegance to contemporary organic —alongside design inspiration and top tips for your next project. What are curved mouldings and where are they used? Curved timber mouldings are specially constructed trims designed for use in curved spaces. This curved effect can be created in several ways: Using flexible polyurethane material Kerfing MDF to increase pliability Applying concave panelling to curved spaces Unlike standard profiles, which are predominantly straight, angular, or flat, our curved skirting boards and custom-made curved architraves are tailored to create smooth, flowing transitions in rounded spaces. Both practical and aesthetically appealing, curved mouldings can accentuate architectural features or expertly conceal joints. The most common applications of curved moulding trim are: Staircases and balustrades – ideal for following the natural sweep of stairways and handrails Entryways and hallways – perfect for emphasising elliptical arches to create inviting transitions between rooms Curved ceilings – beautiful accents to make focal points of barrel-vaulted, tray, or domed ceilings Rounded windows – bay window architraves add elegant detailing to feature windows Wall panelling – to create seamless continuity and make a feature of curved walls Types of curved mouldings at Intrim At Intrim, we know that no two projects are alike. That’s why we offer a range of different moulding options to help you craft a bespoke, curved finish that truly complements the space. Here, we’ll outline the three core types of curved Intrim mouldings, their typical applications, and some recent designs to inspire you to get creative with curves. Curved Architraves Curved architraves are the perfect choice for accenting windows and arches. Custom-made in-house to your unique specifications, curved window moulding architraves draw the eye towards focal bay windows and feature archways, enhancing architectural features while covering gaps and joints where curved walls meet windows or doorframes. Popular Profiles: All of our architraves can be customised into curved profiles, ideal for matching with skirting to ensure a seamless flow throughout. Some of our favourites are Intrim SK1063 architrave for Victorian interiors and Intrim SK60 curved architrave for French Provincial glamour. Curved Architrave Inspiration Curved architectural moulding lends itself perfectly to luxury interiors like this French Provincial Mansion. Designed by Sarah Remaili House of Design and built by Phil Borg at B & C Projects, this magnificent design incorporated Intrim SK961 curved architrave throughout to bring signature French ornateness to stairways, windows, and openings. Concave Timber Mouldings Where custom curved architraves are ideal for accenting existing curved features, concave moulding is used to create curves. These eye-catching profiles feature semi-circular recesses that add stunning texture and architectural intrigue to your space. They can be used on curved walls or flat surfaces to create an attractive and stylish finish on walls, benches, islands and more. Popular Profiles: Intrim CC50 concave timber panelling is a standout for scalloping details. Concave Moulding Inspiration To see the CC50 profile in all its glory, check out Meraki Collective luxury hair salon. Used as vertical panelling around the whole circumference of the reception desk, our concave timber mouldings bring natural texture and shape to the salon’s contemporary, minimalistic aesthetic. Curved Skirting Boards Choosing the best skirting board for curved walls takes your interior design to the next level. Perfectly moulding to the natural flow of curved walls, our flexible polyurethane skirting board material adds effortlessly sleek detail to rounded spaces. From curved rooms to spiralling staircases, a curved skirting board enhances the architectural appeal of dynamic spaces. Popular Profiles: We can create any skirting board profile in a curved design using flexible and durable polyurethane. For modern contemporary interiors our Intrim Shadowline® skirting, which is manufactured in MDF, can be curved by kerfing. For a more classic style interior choose a detailed profile such as Intrim SK245 skirting board. Curved Skirting Inspiration Inspired by the form, function, and flow of nature, the Willow Residences project, designed by BayleyWard and built by Minicon, exemplifies the effortless beauty and sophistication of curved architecture. Sleek, contemporary, and luxurious, this design uses Intrim Shadowline SK800B curved skirting to emphasise the gentle curves of shared spaces to create a beautiful, continuous flow throughout the building. Benefits of Curved Mouldings Curved mouldings give your design scope and flexibility where traditional, straight profiles won’t work. From sweeping staircases to porthole windows to feature panelling, curved wall moulding enhances interiors in the following ways: Emphasises the visual flow between rooms and shared spaces Complements existing architectural form Gives the illusion of a larger space Adds a luxurious, bespoke feel to interiors Which interior design styles work best with curved architraves? Characteristically elegant, curved timber mouldings align best with interior design styles that value softness, organic shapes, or refined details. Our favourite styles for elevating with curves include: French Provincial – this style is all about curvaceous lines and elaborate mouldings to exemplify timeless, lived-in interiors. Classic and Neoclassic – curved doorway mouldings and skirting complement the ornate arches and grandeur of Georgian, Edwardian, and Victorian interiors. Contemporary/Minimalist – a warmer approach to sleek, clean lines, curved trim enhances the organic comfort of rounded spaces. Coastal – curves exemplify the relaxed, natural, and airy aesthetic of coastal interiors, softening the transition between outdoors and in.
