justin posted these stairs recently with the following caption:
The model M400 adjustable helicoid spiral staircase, designed by Roger Tallon in 1964, has a central steel column that supports ten cast aluminum steps and one wide landing stair with spacers. 84”h, steps: 23”w x 10.75”d, landing: 20.5”d. Disassembles for moving. Made to measure and distributed by Sentou in Paris.
initially it occured to me that they might be installed upside down? wouldnt a landing be at the top? better it should be interchangeable as any good modular design. the sentou site linked crashes my browser every time i go there to check so...
