Building a modern L-staircase with a landing - difficult?

[Panelmannen]

I am working on a new build and need an L-shaped staircase in a modern style with hidden stringers. I'm thinking I can cut three stringers and glue MDF as treads during construction, then cover it with Ash or Oak laminated planks that are then oiled. That way, I have both a construction staircase and a finished staircase when it’s time to move in. Like in the picture but with a landing and L-shaped Any thoughts on that? What is important to consider?

Have no answers to give, but I'm interested in what you write.
I'm going to have such a staircase this fall, so I'm considering now whether to buy or build it myself.

I built this out of plywood and during the renovation, covered it with paneling and oak parquet. Made my own stair nosings.
