If you haven't come across Kendall Jenner's rather unique guest room, allow me to introduce you – but prepare for it to become your next interior design obsession.
When acclaimed designer Heidi Callier transformed Kendall Jenner's mountain hideaway, she also took on a rather unique task: converting Kendall's retro trailer into perhaps the most stylish guest bedroom you can imagine.
It might not seem like an obvious choice, but Heidi embraced a glamorous, 1970s-inspired look. By the time the process was complete, Kendall Jenner's retro airstream had become a wood-drenched, pattern-packed haven that gives a brand new meaning to the 'grandma chic' aesthetic (one of 2026's biggest trends).
Even if you don't happen to be renovating a travel trailer like Kendall's, you can steal her look using a few budget-friendly pieces. Below, I've curated an edit of my favorite grandma-style picks, from Wayfair's Tea Cabin cotton throw to Anthropologie's embroidered café curtains.
Recreate Kendall Jenner's Grandma-Inspired Guest Room
The hallmark of grandma style: a patchwork quilt. While Kendall's chic bedroom showcases a striking lime green theme, you'll spot chic olive hues in her throw blanket.
Boll & Branch;s pieces are an investment, but the brand produces some of the best bedding on the market. This crisp floral set gives the perfect nod to grandma style, without feeling kitschy.
Plaid will always bring a cozy, heritage feel to your space, and this one is finished in deep maroon hues. It's ideal for a grandma-inspired bedroom or even a living room.
Nothing says grandmacore like floral-patterned china. These plates wouldn't just look gorgeous on a dinner table, either – they're also a charming wall decor idea.
Café curtains have become rather beloved in the design world, and they're a wonderful addition to any nostalgia-driven room. You can even use them to hide bulky kitchen appliances like dishwashers.
Pay homage to Kendall's spectacular green countertops with this retro lamp. It might feel like a moody color, but it's guaranteed to bring some personality to your space.
The grandma look is all about cozy charm, but I wouldn't say it's the go-to aesthetic for small rooms. (Although it's worth noting that Kendall Jenner's entire mountain home showcases eclectic, nostalgia-fuelled design.)
Especially in a space as intimate as Kendall's airstream, wood-drenched walls and rich-toned fabrics could seem like a risk. There's a reason why the coastal grandmother trend emerged to put an airy spin on the original grandma look: this kind of nostalgic design style might feel like a warm hug, but it can easily teeter toward claustrophobia.
So, how does Kendall's small guest room perfect the art of grandmacore? To me, it's all about confidence – and a strategic use of color.
Naturally, the green countertops are inclined to steal the spotlight, but they also set the tone for the rest of the space. Combining '70s glamor with a more lived-in, vintage-inspired feel, the lime green hue serves as a breath of fresh air. To tie everything together, the patchwork quilt introduces a darker, moodier shade of green.
Naturally, pattern is another crucial element of grandma-inspired design, and this is where Kendall's space really shines. If the kitchen area is a '70s dreamland, the bed is pure cottagecore – and it's a masterclass in pattern clashing.
Once again, a bold blend of prints is a daring move in a small space; without careful consideration, it can make the entire room feel busy and cramped. Here, however, patterns are used strategically, with the quilt acting as a statement piece, while the embroidered bedding and curtains providing a more subtle nod to vintage design.
I love the addition of the patchwork bolster cushion, too. The silhouette cleverly echoes the sweeping ceilings of the airstream, while the print is the epitome of grandmacore: whimsical, elegant, and utterly timeless.
Heidi's design choices are proof that even the smallest spaces can be transformed by retro style. Cozy charm doesn't mean rooms packed full of furniture; instead, simple details can really create that warmth.
Designers say that warm, inviting spaces are what people are striving for this year – and the grandma aesthetic provides the perfect blueprint.
'There's a reason people are gravitating toward grandma chic: it feels welcoming, elevated, and timeless, rather than trendy,' says Libby Rawes, Founder and Principal Designer at Sharp and Grey Interiors. 'Traditional shapes, feminine patterns, and darker colors feel grounded and classic, like these rooms were intentionally layered and curated over time.’
Whether you spend a few hours at the flea market, take some design inspiration from your own grandmother, or simply pick up some vintage-inspired pieces from your favorite brands, this nostalgic aesthetic is within reach. And as Kendall proves, it really does make a small space shine.
