Casting entrance stairs - hollow/polystyrene/EPS for lower weight?

[fredrik_pe]

Perhaps it is somewhat visible in these pictures, I made the blocks "hang" a little more outside each other for each layer to get them under the door. I started the first layer by cutting out one corner to get over the drainage strip, and then continued.

I have "only" put reinforcement rods between the bottom and second layer. Right or wrong, I don't know...

Planning a new staircase, model "pyramid staircase," for a house with a basement foundation after drainage about 2 years ago. This makes it a relatively large piece.

Whatever and however you make the staircase itself, I have a serious piece of advice:
Put up railings/handrails that lead from ground level up to the front door!
Older wobbly people, and sometimes even younger ones, need some support to hold onto when they wobble up or down such stairs.
It must not be open on three sides without something to help visitors stay on their feet and maintain their course!

Older unsteady persons, and sometimes even younger ones, need something to hold on to for support when they wobble up or down such a staircase.

the idea was to have a railing (wrought iron) diagonally in one corner or along one side of the facade, we shall see!

Moving forward

New driveway and the stairs are being covered. First laid a thin layer of fine concrete. Came across a cheap batch of 60x90x3 cm granite (second grade) at flisby, a lot of cutting but it feels worth it!
