Cells by EeStairs

Cells™ stairs, an exclusive innovation by EeStairs, combine art and geometry in an elegant and unexpected way. The organic open weave design of Cells™ steel balustrades are derived from computer-generated Voroni tessellations, which form a flowing ‘weave’ of laser-cut steel cells.

As a result, no two Cells™ balustrades are the same, guaranteeing that every Cells™ staircase is unique. And the balustrades form a strong integrated structure with stringers, treads, or floor edges.

Designers can choose the density and shape of the cells – for example, polygons, bubble patterns, or a range of cell sizes to produce balustrades that have a delicate or monumental character.

The advantages of Cells™ balustrades:

  • Shapes. Cells™ balustrades can be straight, curved, spiral, elliptical, or asymmetrically radiused.
  • Stylish. 2 Cells™ balustrades create a stylish and artistic effect.
  • Unique. The pattern of each Cells™ balustrade is individually unique.

Customising Cells™ stairs

Cells™ stairs can be customised in the same way as EeStairs customises more familiar stair types. The cellular balustrades can be seamlessly and securely attached to steel stringers, or directly to metal or wood stair treads or floor edges.

The steel balustrades can have irregularly shaped polygonal cells or irregular bubble patterns, and they can be factory-painted in any RAL colour, or given different patination treatments. Designers can also specify the size of the cells – for example, smaller cells at the base of the balustrade which rise to more open cells, or a random array of small and medium sized cells to create a more monumental balustrade.

Cells™ stairs can also be designed and made as a ‘double-act’ with a glass, wood or solid metal balustrade on one side of the treads, and a Cells™ balustrade on the other.

Because Cells™ balustrades are made of steel, designers can specify tighter radiuses on the stringers without compromising the strength of the stair structure as a whole.

Can I specify a general type of cell pattern, such as angular or circular?

Yes, EeStairs can make almost any form of Voroini cell patterns.

What is the geometry of Voroni diagrams?

Voroni diagrams are produced by randomly positioned points on a plane which create asymmetrical cells around them.

Is every Cells™ balustrade unique?

Yes, because the cell pattern is randomly generated for every project.

What is the Cells™ balustrade made of?

The balustrade is made of steel.

Can I choose any colour?

EeStairs can apply any of the 200-plus RAL colours.

Can the Cells™ balustrades be curved?

Yes, and relatively tight radiuses are possible.


Cells™ stairs are ideal for domestic, commercial, and office interiors where the designer or specifier wants stairs that combine elegance, strength, and Wow Factor. EeStairs have made and installed Cells™ stairs in stylish homes in cities including Paris, London, and Moscow. In Amsterdam, EeStairs installed a multi-stage Cells™ office staircase at Amsterdam’s Schiphol Airport.

The unique aesthetics of Cells™ balustrades, and their steel structure, means they can be used at the edges of floors, such as the perimeters of atriums, stairwells, and patios to make a strong design statement.

Installing Cells™ stairs

The installation of staircases with Cells™ balustrades is straightforward and has no cost premium: they are installed in exactly the same way as EeStairs installs all of its other types of stairs.
