ᐅ Requesting opinions and experiences regarding the choice of interior stairs

Hello dear forum members,

our interior construction plans for a semi-detached house are well underway. The staircase is now the focus, and since we are not experts, we are very interested in professional opinions.

Floor Plan

The stairwell is planned in the middle of the semi-detached house. Two staircases extend over three floors (basement, ground floor, upper floor). The staircase is designed as a double quarter-turn staircase. Here are the floor plans for each level.

Our Requirements for the Staircase

• The staircase should have both treads and risers
• Stringers or beams should be minimally visible or "invisible" if possible

Staircase Options

The current selection includes the following staircases (and ideas):

• Double-stringer staircase (standard). This is included in the purchase price.
• Applied stringer staircase with folded framework design and railing. The additional cost for the complete staircase system is about $14,000. Example images:







• Another idea: double-stringer staircase between walls with LED spotlights on the wall side and a handrail on one side. Similar to these images:







• Another idea: recessed stringer staircase between walls with LED spotlights on the wall side and a handrail on one side. Similar to these images:

Our Questions

We don’t really like staircase option 1 (standard) very much. We have a few questions about the staircase options:

• Regarding option 3: Our staircase builder mentioned in a brief conversation that a double-stringer staircase with risers can sometimes be noisy (occasional creaking). He recommends a stringer staircase when risers are used. Is this true? Does anyone have experience with this?
• Regarding the staircase between walls (options 3 or 4): Walls naturally reduce light penetration. Does the lack of light impact our floor plan significantly? Should option 2 be preferred instead?
• Do you have other ideas?
