The mezzanine has many assets. It saves space or dress in a very elegant way a high ceiling. Most often open space installed above the living rooms, the stairs leading to the mezzanine must combine accessibility and aesthetics.

Some simple rules to choose the stairs of your mezzanine

As for any staircase the choice of a model and shape stairs leading to a mezzanine depends on any other consideration of the place you have.

Under the mezzanine height must be at least 1.20 m. So you will not feel overwhelmed by this mezzanine. On the mezzanine itself, 1.90 m is the minimum to be able to move at ease.

These heights of bases laid, it is now necessary to see what volume the staircase can occupy in the room of the ground floor. Depending on the available space, the climb and of course the descent will be more or less steep. As much as doing this little, avoid sacrificing comfort to aesthetics, especially if you have to borrow this staircase several times a day.

How to calculate the ideal height of a staircase?

The rule was given by an architect of the eighteenth century, Jacques-François Blondel. And do not neglect the experience of the old, this prescription is still relevant even if it can be somewhat adjusted depending on the circumstances and especially depending on the available space.

A staircase will be all the easier to assemble and even more so to descend if it respects the following proportion:

2 X H + G = 63 cm

H being the height of a step that is multiplied by 2.
G being the lap, that is to say the width between two nosings (this corresponds in fact to the useful width where we can put the foot)

The ideal staircase to a walking height of 17 cm and a step of 29 cm:

17 cm X 2 = 34 + 29 cm = 63 (an angle of about 30°)

Choosing a staircase that saves space for a mezzanine

Unless your mezzanine is installed in an old industrial building converted into a loft or a barn, the real problem to choose the stairs of a mezzanine is to be able to occupy the least space possible.

Fortunately, several solutions are available to you:

  • The miller ladder: It's the simplest. A flight of straight steps without risers. In addition each step is more or less superimposed on the next which allows to limit almost half the footprint of the stairs.
    On the other hand, the miller's ladder forms an angle which is at about 70°, compared with the 30° angle of the ideal staircase... But it remains quite practicable.
  • The staircase with Japanese steps or staggered steps: This is actually a ladder miller whose steps are cut so as not to overlap. Thus the first step is wider on the right than on the left and conversely the second step is wider on the left than on the right and so on. You just have to start on the right foot, otherwise it's really complicated...
  • The spiral staircase or spiral staircase: The steps are wrapped around a central core. It can be square or circular. Elegant, it seems to take up little space. Paradoxically, compared to the miller ladder or the Japanese step ladder, it requires a hopper at least 1.30m in diameter and it occupies the same volume on the ground.

On the other hand, it is useless to think of passing Aunt Adélaïde's old solid wood wardrobe by such a staircase. While you do not move every day but the day comes, it will not make it easy.

In conclusion: Once you have chosen the shape of the stairs leading to your mezzanine, the different materials available will allow you to adapt it to your decoration and your budget. Wood remains a noble and timeless material. Steel, aluminum and stainless steel bring you lightness and modernity. Concrete and stone need space unless you choose a suspended staircase. The glass is bright. Or combine the qualities of each material to create YOUR mezzanine stairs...
