A studio devoted to design, entirely on your side
H&H CONCEPT is a Parisian interior architecture studio. Our craft: imagining and preparing your project down to the finest detail, then guiding you to the best professionals to build it.

Who is H&H CONCEPT
H&H CONCEPT was born of a simple conviction: the most beautiful interiors are born of rigorous design, not on-site improvisation. Based in Paris, the studio designs apartments, houses and professional spaces for clients who value elegance, precision and peace of mind.
Our practice is nourished by the masters of the discipline — Joseph Dirand, Vincent Van Duysen, John Pawson — and by a deep taste for noble materials: marbles, European woods, brushed brass, tadelakt. We remain deliberately small: every project is followed personally, from first exchange to the delivery of the complete design file.
Why design only?
Because it guarantees your interest. When the same firm designs and builds, the design bends toward what is easy or profitable to execute. By devoting ourselves exclusively to design, we draw what is right for your project — and give you a complete, precise file on which building companies compete on identical terms. Our only interest is yours.
Why partner companies?
A beautiful project poorly built does not exist. Site after site, we have assembled a network of craftsmen whose work we know first-hand — electricians, plumbers, joiners, kitchen makers, painters, marble masons, parquet layers, home-automation integrators. We organise their consultation on your project; you choose freely, with full legal guarantees carried by the companies.
