I will however make an update on what happend last Saturday after i posted my previous blog post, because the crew was working on the stairs foundation and I wanted to share some photos of the progress.
The construction was done using three concrete beams, that was anchored at the new base and at the mezzanine floor. The beams were then filled with light foundatoin stones - as you would do if you were creating a ceiling/floor devider between two apartments.
Then a mesh iron wos added on top of the beams and the whole thing was filled with concrete. The stairs will be built on top of this foundation.
