This week's lookbook rounds up eight interiors with furnishings and surfaces finished in burl-wood veneer, allowing its swirly, psychedelic graining to serve a decorative function.

Burl wood is a rare and expensive wood, often only available in thin sheets of veneer. That's because it is derived from the knobbly outgrowths of tree trunks and branches – also known as burls.

Like the botanical equivalent of a callous, these outgrowths form in response to different stress factors and grow unpredictably, creating complex unexpected grain patterns behind their gnarled bark.

Burl wood has been experiencing a renaissance over the last few years, with interior designers including Kelly Wearstler using it to evoke the bohemian flair of its 1970s heyday.

Mixed and matched with other patterns, the material is now used to communicate a kind of organic understated luxury, much like natural stone.

From a Michelin-starred restaurant to a home that was designed to resemble a boutique hotel, read on for eight examples of how burl wood can provide textural richness to a modern interior.

This is the latest in our lookbook series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring rooms with net floors, interiors with furry walls and homes with mid-century modern furniture.

Botaniczna Apartment, Poland, by Agnieszka Owsiany Studio

This tranquil apartment in Poznań was designed by local firm Agnieszka Owsiany Studio to give the owners a reprise from their high-pressure medical jobs.

Koda hair salon, Australia, by Arent & Pyke

This hair salon in Sydney's Queen Victoria Building was designed by Australian studio Arent & Pyke to be "best appreciated from seated height".

Opasly Tom restaurant, Poland, by Buck Studio

Buck Studio employed a limited palette of colours and materials to create visual continuity throughout Warsaw restaurant Opasly Tom, which occupies a split-level building that was broken up into a series of rooms of different sizes.

Coral-orange chair cushions mirror the hardware of the totem-like pendant lights, and several burl-clad cabinets are dotted throughout the eatery. These match the kaleidoscopically patterned panelling in the hallway and the private dining rooms.

"This contemporary, minimalistic design approach produces the impression of coherence while creating a powerful aesthetic impact," explained the Polish studio, which is headed up by Dominika Buck and Pawel Buck.

Warsaw apartment, Poland, by Mistovia

Elsewhere in Warsaw, Polish studio Mistovia designed an apartment for an art director and her pet dachshund to resemble an "elaborate puzzle" of contrasting patterns.

Walnut-burl cabinets dominate the kitchen, with their trippy swirling pattern offset against monochrome tiles, brushed-metal drawers and a terrazzo-legged breakfast bar.

Imperfecto, USA, by OOAK Architects

Upon entering Michelin-starred restaurant Imperfecto in Washington DC, diners are greeted by a custom-made maître-d stand clad in panels of burl-wood veneer, creating a mirrored tortoiseshell pattern across its surface.

The interior, designed by Greek-Swedish studio OOAK Architects, sees neutral tones paired with splashes of blue and white that nod to the restaurant's Mediterranean menu.
