304.cage is a creative design studio based in Rotterdam, the Netherlands, founded in 2023 by Bram Schlangen.

We focus on designing furniture and interiors that stand the test of time and elevates interior spaces by offering both style and innovation. With every project, our aim is to ensure that it not only serves its purpose, but also becomes an integral part of the interior spaces it inhabits. In addition to our focus on furniture and interior design, 304.cage also specialises in set design and creative direction for art and fashion projects.
