Hmm, I think a straight handrail generally doesn’t work for a spiral staircase. It really doesn’t look very good in the picture.

What do you mean by straight?

Here’s another version with an additional bend.

I also have a space-saving staircase leading all the way up to the (converted) attic. The railing and the shape of the stairs are exactly the same as in your first picture. It works well.

It does look strange. In our case, it is solved with a curvature, but we have a half-hip roof. What does the professional say?

By "straight," I mean the straight handrails. Usually, the handrail follows the staircase's curve, but your version looks segmented and like a "cheap fix" because smaller straight handrail sections are simply joined together to follow the winding shape. In the photo, it also seems like it wouldn't be very comfortable for the stair user to grip, as the shape looks odd. So, I would really reconsider that; it’s noticeable immediately.

Also consider the other quality requirements of a handrail, whether you are walking up safely in the light or going down in the dark with a stubbed toe.

I would first ask local metalworkers and glaziers how they would approach this. It will probably be more expensive than doing it yourself with materials from the home improvement store, but it is definitely superior both visually and functionally.
