Inspired by biomechanics, the project is based on the structural principle of a spine. Along a helical concrete beam, « vertebrae » (the term chosen to designate the steps) rest against one another to form a complete staircase system. Each step consists of a module that can be replicated indefinitely. Made of UHPFRC (Ultra-High-Performance Fiber-Reinforced Concrete), it is carefully designed to optimize the amount of material used from a sustainability perspective. The core of the modules is hollowed out to reduce mass, creating a graphic, almost weightless aesthetic.

Born from a very simple idea—that of a concrete wall being peeled away layer by layer— »Peel Concrete » is a staircase that is both graphic and minimalist.

Although made entirely of concrete, we sought to bring a sense of flexibility and lightness to a material that is traditionally rigid and massive.

A system of factory-prefabricated modules simplifies installation through an interlocking mechanism. The suspended wire-rope railing reinforces this concept of lightness while increasing the structure’s physical strength.

Getting back to basics, living in the moment. How can we use a staircase to disconnect, if only for a few seconds?

Through this project, we advocate for a return to the very essence of the object, pushing the reflection on « what we have right now » to its absolute limit. A staircase, no matter how innovative, must not fail its primary function: moving from one level to another.

We therefore based our concept on its core definition—creating a simple element that retains its original purpose while blending design and science. By pushing the material to its absolute limits, the form naturally reveals itself.

We view the staircase as something that belongs entirely to its context and the space it occupies; it is this synergy that creates a whole. This is why we chose to design a semi-recessed staircase, allowing it to adapt into various forms.
