Dubbed the first major design trend of 2024, our latest lookbook collects cosy, lived-in interiors that embody the "bookshelf wealth" aesthetic movement taking over social media.

While using books for interior decoration is not a new idea, it has been brought back into focus by a now-viral TikTok video posted in December by San Diego-based interior designer Kailee Blalock.

In the video, Blalock explains that "bookshelf wealth" is not just about creating perfect book displays, but instead about capturing the warmth and homeliness of book collections to curate "a whole home vibe".

"Bookshelf wealth", which the Financial Times called this year's "first major design trend", suggests pairing bookshelves with mismatched interior patterns, cosy seating areas and layered, loosely organised art pieces to create a tastefully eclectic space for reading.

Despite their contemporary qualities, the projects in this list capture the intimate atmosphere of "bookshelf wealth", from colourful bookshelves that span an entire room to subtle reading nooks for deeply personal collections.

This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration, see previous lookbooks featuring spaces punctuated by structural columns, rooms embracing the "unexpected red theory" and playful homes integrating indoor slides.

Mayfair home, UK, by Child Studio

London-based Child Studio designed this entertainer's home in Mayfair with mid-century modern furniture and deep-toned material finishes, aiming to enhance the art deco atmosphere by carving bookshelves into dark mahogany walls.

"We worked closely with the client to create a space that reflected his personality and interests, encompassing art, design, literature and travel," Child Studio founders Che Huang and Alexy Kos told Dezeen.

"This approach made us think of Saint Laurent's salon – an eclectic interior where design objects and art pieces from different eras and parts of the world are assembled together, forming a highly personal environment."

Santa Monica Proper Hotel, USA, by Kelly Wearstler

The Santa Monica Proper Hotel by American designer Kelly Wearstler includes reading niches with artwork and furniture by local artists and artisans.

A brimming bookcase flanks low-lying lounges and walls covered by misaligned artwork, with Wearstler explaining that the idea was to connect the original building's Spanish colonial revival style with the new contemporary building.

"Everything's connected to somebody that is local in the city," Wearstler explained. "We're so lucky to be in Los Angeles, the talent pool here is extraordinary."

Kew Residence, Australia, by John Wardle Architects

Remodelled by John Wardle Architects for the founder's own Melbourne home, Kew Residence leans into the informal and cocooning atmosphere of "bookshelf wealth" in its wood-clad first-floor study.
