This Mash-Up Design Style Will Be Your Home Decor Crush Soon

We've scoured markets and feeds to spot the standout looks shaping home style next year. From "Covecore" to bold colors, stripes, and DIY projects, see every trend we're calling in our full New/Next List.

At the start of 2020, Apartment Therapy predicted the resurgence of Art Deco style. The movement’s centennial anniversary felt like the moment for the interior design world to look back at Deco’s soft curves, shiny finishes, and streamlined geometric motifs to recast them anew. And that’s kind of what happened: Over the past few years, sofas have become increasingly curvy, pared-down graphic patterns have stayed popular, and Pinterest proclaimed bold chrome the “it” finish of 2024 after years of brass being dominant.

But what we didn’t totally clock — until now — is how this 21st-century Deco might itself evolve (and potentially in retrograde). Because in the past year or so, we’ve been seeing a style that’s seemingly a shift back to what the original Art Deco movement was a reaction against: Art Nouveau. But it’s not Art Nouveau in its purest form. What we’re seeing is a trend blend we’ve dubbed “Retro Nouveau.”

Retro Nouveau is a mashup design style that takes the organic motifs, stained glass, and ornate shapes of Art Nouveau and melds them with retro (and even Deco-coded) touches like bold colors and geometric patterns. Examples of these interiors certainly include vintage and vintage-inspired touches, but modern and contemporary pieces can be mixed in, too. 

This might not be the first time you’re hearing about Retro Nouveau. Back in December 2024, for Apartment Therapy’s The State of Home Design designer survey for 2025, we soft-sounded 154 designers on what they expected to be an emerging design style for the year. Almost half — 44% — of respondents chose Retro Nouveau for its vintage-inspired, quietly luxurious, and borderline fancy aesthetic.

Trying to spot this style in the wild? From what we can tell, the magic is in the mix. Think putting a very Nouveau Tiffany lamp on a carved buffet depicting greenery and animals next to a very 1950s-looking piece of artwork, as renter Francesca Grace did in her former LA apartment. 

You can follow pro designers’ leads, too. Mix a bold animal print wallpaper with a faceted mirror and custom-cut, bowtie-shaped stone vanity backsplash, like designer Dara Beitler did in the powder room above. Or hammer home the retro vibe even more à la designer Amanda Jacobs in her bar project below. There, she mixed classic checkerboard floor tiles with Cesca-esque chairs and punchy colors (think: teal walls and Deco-inspired, channel-back mustard banquette-style seating).

Taking a step back from these specific examples, though, the Retro Nouveau interiors we’ve been spotting seem to share some of these characteristics:

• Nature-inspired patterns that are highly stylized and whimsical (vs. realistic) 
• Stained glass windows, doors, and accents
• Gilded and high-shine finishes
• Sinuous shapes and ornate details/ornamentation
• Darker woods and bolder colors like pinks, maroons, browns, blues, and greens
• Retro-meets-Deco design elements like checkerboard floors and geometric prints
