ABOUT US

KADER - Alexander Mercer

KADER DESIGN is an internationally oriented online gallery offering a distinct collection of high-end antiques, true vintage furniture, and art from the early 1900s to the rise of European Modernism and beyond. Our focus lies in sourcing rare, timeless pieces — often designed by architects — that stand out for their visual appeal, historical relevance, and quality.

What sets us apart is a rare collection built over more than a decade: objects with a story, often under-recognized, always carefully selected. We work with interior designers, architects, collectors, and museums around the world — clients who come to us for our eye, our consistency, and our reputation for being ahead of the curve. 

KADER DESIGN exists to inspire, to preserve, and to be that rare place where discovering something truly valuable is never by chance. We believe in lasting quality. In aesthetics that hold their ground.

The gallery is shaped by founder Alexander Mercer (1984), whose background in art and design, combined with a collector’s sensibility, forms the core of KADER DESIGN. His approach is rooted in history and sharpened by experience. His signature aesthetic is met with appreciation all over the world.

Research is essential in our practice. Throughout the years, KADER DESIGN has developed an extensive archive of reference material, monographs, and authentic catalogues, providing invaluable context to the collection at large. We are always interested in exchanging thoughts and knowledge.
