Roger Tallon’s helicoid spiral staircase

Tallon staircase, with unusual rail

This disassemblable spiral staircase by French industrial designer Roger Tallon is, not surprisingly, in the design collection of the MOMA. It is both ingenious in engineering terms and beautiful. Tallon is one of those prolific and versatile designers responsible for a diverse collection of projects. Among many other things these include the Wimpy chair, cutlery, TVs, sinks, France’s streamlined TVG high speed train, and more recently he was the design director for the Eurostar trains as well. Yet oddly he’s not all that well-known outside France—for example there’s no Wikipedia entry for him in English. This is strange when you take the breadth and quality of his projects into account. How does that happen?

This 1964 staircase, officially called the “model M400 adjustable helicoid spiral staircase,” has a central steel column on which are strung ten cast aluminum steps, one wide landing stair and the spacers. The M400 is still being made, and if you are sitting on a lot of disposable income you can have one. The top image of the staircase is a recent photo by an auction house, and it shows a very nice after-market hand rail. The staircase comes with no rail so there were many interesting custom made solutions to the rail problem, not usually as nice as this one. I recently found photos of the staircase as installed in a modernized 60s room in an old Paris house, below, in the 1973 decor book 1601 Decorating Ideas for Modern Living.

    I really love the idea of a spiral staircase, but have always wondered how you get a wardrobe, chest of drawers, or bed up to the bedroom. Any ideas?

  2. admin Says:

    John, I know. It would require either magic, or a crane. I think a spiral stair has to be a secondary staircase, up to a reading platform or something, and then you’d also have a regular staircase as well. (Or you just buy a cherrypicker and hoist everything in through a big upstairs window.) However my aunt has a spiral staircase in her handmade house, and a big mezzanine balcony at the top. She took smaller pieces of furniture up the stairs, and the larger ones they just hoisted up from the balcony. For her, the spiral staircase was a big space-saver.

    I have 2 pairs of Roger Talon cast aluminum staircases each 12′ tall that I would like to sell. They are in Sarasota Florida.

    From someone who builds a lot of staircases for a living, Roger Tallon’s spiral staircase has a wonderful design to it. I like how simple and clean it is, and how it doesn’t take up a lot of space.. But I agree it would be pretty hard trying to lug a dresser or something up them! From an aesthetic view point, however, this staircase is wonderful.
