Belgian designer Bieke Casteleyn, who studied in Ghent and Milan, founded her studio in 2012, driven by a passion for exploring space, form, and materiality. Her 'Out of Line' collection, launched in 2015, showcases a blend of craftsmanship and sustainability, with cement plaster as its core material, paired with wood, suede leather, and glossy lacquer finishes. In 2024, the collection grew to include a sofa line featuring exclusive fabrics, and in 2025, new furniture pieces will be added. 'Out of Line' defies rigid lines, merging organic textures with refined elegance to create timeless, sculptural designs.

ALPI is a leading manufacturer of decorative surfaces made of reconstituted wood. Being the first to industrialise this process, ALPIlignum veneer is made of real wood by taking apart and putting back together a tree–trunk. This creates a material that is not printed, and so designable as to offer limitless aesthetic effects. ALPI represents an undisputed gold standard in wood technology. The ALPIlignum Collection is FSC® 100% certified (FSC–C004666), thanks to full control of the supply chain.
Profound synergy between ALPI and the design world has given rise to long–standing collaborations with design talents. Piero Lissoni has held the role of art director since 2015. ALPI products are distributed in more than 60 countries.
