Furniture and painting restorer. Antiques dealer. A life devoted to things that outlive us.
Whoever steps into the workshop at Wittgensteinstraße meets a man who reads furniture the way others read books. Isai Liven has devoted his working life to antiques: as a furniture and painting restorer who cares for private and state collections, as a dealer with an unerring eye, and as an appraiser whose judgment is sought and trusted.
His focus: restoration, consulting, transport, and storage of fine everyday and art objects from all eras. His workshop is a certified Meisterbetrieb — but those who know him would say his real qualification is simpler: he cannot bear to see a beautiful thing suffer.
“I am not the owner of these pieces. I am one chapter in their story — and my job is to make sure the story continues.”Isai Liven
His desk stands beneath a monumental tapestry, surrounded by Art Nouveau lamps, amethysts, and paintings — not staged, simply grown over the years. Here he receives collectors, curious neighbors, and anyone who brings an old piece with a question.
Conversations here rarely stay short. They begin with a piece of furniture and end with history, craft, and the question of why some things are made to last.
Between restorations, the easel comes out. Isai Liven paints — and whoever restores paintings understands them differently when he makes them himself: how a stroke sits, how pigment ages, where a picture breathes.
It is the quiet side of the same craft: the restorer preserves what the painter knows how to create.
Whether you are looking for a piece, own one that needs care, or simply love old craftsmanship — the door at Wittgensteinstraße 13 is open.
