Cost/planning of an elevator for future needs in new construction

... adds the stairwell by one elevator shaft. Then your problem is solved without additional costs.

You can also plan a small storage room stacked on each floor, and just close the ceiling there with 'boards', that certainly won't cost 4,500.

What is a lifting eye? Could you explain that to me? Thanks for the ideas. :)

I would personally not install a stairlift. I experienced with my parents that they often fell when transferring from the wheelchair to the stairlift.

What is a lift eye?

A stairwell is the space between the flights of a multi-flight staircase through which you can look down from above. In movies, you see people falling to their deaths there, or an elevator running through with a cage around it. What is meant here is: create next to your stair outline (that is, in the "stairwell opening" of the ceiling) enough "air space" so that the elevator will fit in later. That way, no separate ceiling opening is needed elsewhere.

Hello Infors

I had a lift shaft installed from the basement to the upper floor. I separated the individual floors with wooden beams and parquet and use them twice as a storage room and upstairs for books. Behind the lift shaft runs my utility shaft. You have to consider with the elevator that a recess (underpass) is necessary. That costs a bit extra because the floor slab has to be formed differently. Something like a sump pit. But I consider 4,000 to be too high.
