The Radaschitz brothers are master craftsmen, having studied at The Ortwein School. Subsequently, they now own and run a family joinery business established by their great-grandfather in 1923. The workshops are based at the foot of Riegersburg Castle in Austria.

Worldwide, they have become an authority in luxury joinery. The Radaschitz brothers went on to found London-based Company INTERIOR-iD in 2006. Their precision-engineered joinery has been commissioned by respected designers such as Martin Kemp and Katharine Pooley, as well as high-profile developers including Finchatton and Candy & Candy (One Hyde Park). Bernd and Johann employ over 80 people across all of the brands. In conclusion, Bernd and Johann’s energy, flair and vision make them key figures in the world of design.

With headquarters in London and studios in New York and Vienna, we bring elevated Austrian craftsmanship to the most prestigious luxury residential spaces across the world.

Combining design, in-house manufacture, and project management, we offer a seamless, fully integrated service tailored to private clients and industry professionals alike.

From early concept to final installation, our design-led and production-led pathways provide the flexibility to suit your vision, process, and pace.

This allows us to craft bespoke solutions for every room in your home or residential project. Discover how we can create, produce, and transform your project, setting a new standard for contemporary craft.

Every project is a handmade story, and the beginning starts with you. Some clients begin in the early stages, and work with our in-house design team to collaborate on a concept, whilst others bring a fully developed design for us to engineer and manufacture.

Whether design-led or production-led, our creative and technical experts work hand in hand to bring all the elements together, from the initial brief to the completion of the project.
