Wooden staircase for a plaster house?

[Genvägen]

We have an old entrance stairway with a steel frame and cast risers.
The house is white stucco with black fascia boards, etc.
The steps have served their time, and it's time to remove them.

Will it look okay to replace them with pressure-treated wood instead? I'm thinking of using 34mm or 45mm boards.

The alternative is to cast new steps or hire someone to build with stone.
The budget probably doesn't quite allow for that.
At the back of the house, there's a wooden deck.

What would you do?

Spontaneous: It won't look good, but if it's a question of a temporary solution, it'll have to do. The risk is that it'll drag on for several years if you don't do it properly right away. I have a friend who made a temporary staircase (4 steps) out of unpainted particleboard, down to the living room. It stayed there for over ten years!

I haven't seen a staircase like yours, but shouldn't it be possible to cast your own risers. If the shape of the risers isn't complicated, it should be easy to shape and cast (don't forget the reinforcement!). A hilti usually doesn't cost much to rent if it's needed to remove the old steps. Take the opportunity to repaint/touch up the frame when it's free from concrete. (if rust: rotating wire brush, sand, Work in the primer thoroughly with brush, then you can roll. If there's severe rust, "tap" first, before the wire brush.)

There is pigmented wood oil from Jotun, among others, which I believe can be almost black. Could be ok. But absolutely best to cast steps yourself in concrete with iron oxide, so you also get black steps.
