The Millen House is an Amsterdam-based gallery and project space founded by architect and curator Niek Schoenmakers. The gallery specialises in carefully selected post-war and contemporary art and collectible design, bringing together works that reveal the enduring dialogue between art, design, and architecture.

The gallery's curatorial vision is rooted in the belief that the strongest collections are built through meaningful relationships between objects rather than through categories or chronology. Historical and contemporary works are presented side by side, creating unexpected connections through geometry, material, craftsmanship, and spatial thinking. This approach encourages collectors to discover new contexts and acquire works that resonate beyond a single discipline.

Alongside internationally recognised artists and designers, The Millen House is dedicated to rediscovering overlooked figures whose work deserves renewed attention, while supporting a new generation of makers with a distinctive artistic voice. Research, provenance, and connoisseurship form the foundation of the gallery's programme, offering collectors carefully vetted works with lasting cultural significance.

Through exhibitions, installations, and curated presentations, The Millen House seeks to inspire thoughtful collecting—where art and design are not viewed as separate fields, but as part of a shared cultural and architectural narrative.
