The staircase was completely tailor-made,
including everything from the diameter
to the depth of the steps to the size of the

adapt the staircase to it."
Though the staircase is popular in
homes, it has its fans in the commercial and
retail arena as well, she adds. In 2016, the
Concorde received a special mention in the
building products and access category at the
Architizer A+ Awards.
When it comes to lighting up the room,
Marretti's Compon is the staircases of choice.
The staircase can be supplied with a closing

creates an illuminating glow. "Our customers can't get enough of this staircase," Marzi
