"With 47 floors of living space it was intended to be the tallest residential building in Europe…The towers were originally designed to be only 20 floors high, but ambitious developers decided to double the scale of the project midway through.
A lift exists for the first 20 floors, but beyond that there is only the stairs. And reports seen by Spain’s El Pais newspaper suggest there is no more space for another lift or motor equipment."
I can only assume that the developers had no particular moneteray incentive in the units being sold. This obviously can’t be any kind of mistake, so whoever had this built probably knew he would get some profit just from building it, regardless of whether it could be inhabited or not. The alternative (nobody in charge noticing that elevators were missing and that it would be a problem) seems impossible.
It is an unusable building. It will have to be torn down and re-built. I’d hate to be the architect, or whoever decided to change the building from 20 to 47 floors.
We live on the sixth floor and routinely walk up. It’s about the only exercise we get. I’d say that’s about the limit. If we were on the 7th floor, I might be taking the elevator.
