Because of the huge number of comments around the world about my floating staircase design I explain the mystery which people want to know.

First of all, this stairs goes to a small maintenance loft zone for climatic systems, there is another type of staircase to go to the bedroom zone. I design this type of staircase thinking in a sculptural solution because it is situated in front of the principal entrance of the house and we don’t want a collapsible staircase which some designers use for zones with difficult entries, we want something different.

This loft zone it’s 2,40 m height and combines wall and glass wall. Is there, between these two types of walls where I’ve done a width change that people can use like a handrail. It is not appreciated in a front view but you can notice it in a side view. This camouflage handrail will see you to the 1,20 m height which corresponds to the half of the staircase.

Steel is the material which we use to construct the staircases, 100 mm thick and each of them is welded to a 250 mm thick beam. The secret is putting reinforcements to prevent the inertias that can be generated and another one is lean the beam on two walls: the front wall and the lateral.

The staircase is 65 cm wide and it can support 200k, consequently we get the minimal flexion. To obtain the minimal vibrations too, we line the lateral walls with a carton plaster plaque.

This is the result of my floating staircase design.
