What is Treillage? Designers discuss the classic, garden-inspired style that's making a comeback in 2025

Designers and brands are constantly providing us with new inspiration, and it feels like every week we are met with a new trend. And while we all love discovering new looks, deciding what's just a passing fad and what styles have longevity can be tricky. So when we see a 'trend' that's actually a tried and tested look that's been around for centuries, we are interested.

While the name may not be familiar to all, you'll certainly recognize this quintessential style as it's been featured in homes for decades. Taking its form from a garden trellis, the 'treillage' style has inherently classical roots. Its signature lattice-style construction is inspired by historic architecture, reminiscent of a traditional conservatory or tea room.

Designers have long been using the style in their projects due to its ability to elevate rooms relatively easily, as treillage tends to be all about the wallpaper. But it's definitely having a resurgence for 2025 as we continue to love characterful interiors, so we've turned to the experts to help us define the treillage design trend and offer tips on how to incorporate it into the everyday home.

What is treillage?

'Treillage' is a French word inspired by the classic lattice construction usually found on a trellis. Traditionally, treillage would be composed using vines, woven together, and layered using latticework. It's a deeply historic technique that's become convention and can usually be found in a backyard, most commonly seen on fences, arbors, or garden porticos.

It's long been popular to 'bring the outdoors in' by creating nature-inspired interiors designed to uplift the spirits and provide tranquility through the beauty of nature. There are so many interior design styles that encompass this ideology, from landscape murals to botanical wallpaper, you'd have likely seen some form of the outdoors weaved into the everyday home. Treillage is one of these many forms and is unique in its individuality. It's an instantly distinctive style that feels grand yet calming, making it a one-of-a-kind choice for home design.

House of Hackney has been inspired by treillage for many of its designs, as Katrina Dalley, the brand's Interior Design Executive explains of their prints, 'The design is neo-classic and romantic. It's inspired by Madeleine Castaing – one of the 20th-century decorating greats and has a French, mid-century feel.'

Why is treillage making a comeback in 2025?

With designers returning to characterful, maximalist decor, it's hardly a surprise that treillage is making a comeback in 2025. It's definitely not a style that falls under the realm of minimalism, so as we witness a shift away from pared-back spaces we expect to see more and more of this classic lattice-style look.

And the look is very in line with spring decor too, so we are seeing plenty of treillage-inspired designs in the new collection. Wallpaper and fabric specialists, De Gournay has recently launched a wallpaper collection in collaboration with PINTO which takes inspiration from treillage. The collaboration features two wallpapers. The Woven Trellis (pictured above) depicts 'the interlocking weaves of natural wicker.' The latter is La Cabane (pictured below) which 'conjures a beautiful trompe l’oeil effect in its rendition of trailing vines and darting swallows amidst an ornate trellised arbor.'

Treillage-style wallpaper has been featured in Graham & Brown's collection too. Paula Taylor, Head Stylist & Trend specialist at the brand, puts the resurgence of this trend down to its timelessness.

'It's a look that never goes out of fashion as it doesn’t follow any particular trend – it is timeless!' she explains. 'It combines longevity with beauty creating a sophisticated look that never goes out of style. The repetitive nature of the design calms and soothes away tension, calms the mind, and helps create the perfect relaxing backdrop.'

How to embrace the treillage trend

While many treillage looks make a bold statement, there are many subtle ways to incorporate the pattern into the home. From wooden paneling to printed wallpaper, it's entirely up to you how far you take the look.

'A neutral palette would suit styling with natural woods and layered textures to create a serene look.' says Paula. 'Or in a bold dramatic interior, it would add a calming respite to maximalist patterns on furnishings whilst still adding a touch of drama with beaded detailing.' Referring to their Treillage Bead Wallpaper, Paula adds that the texture brings a 'new dimension thrilling the haptic senses with their wonderful tactility.'

Treillage has previously had a formal, fussy status which can easily be avoided with the right styling and decor choices. Katrina Dalley of House of Hackney recommends keeping things cohesive and matching the key colors of the wallpaper to your furnishings. She explains, 'You could go bold with the accessories and use bright pops of red to match the flowers in the Cinnabar colorway and they can add playfulness to the room. There are also warmer, more yellow tones in this print so you can feed into this palette with some warm neutrals.'

We can see why treillage has such a vast history, being used in interiors across the globe for decades. Its ability to add calm yet embellish a space is why designers have incorporated it in their designs and why we're seeing a revival of the style in 2025.
