Sorry, I haven’t been following everything so closely anymore. Why exactly is the utility room placed so centrally on the upper floor? I would rather think in this direction:
It just happened that way. Better than having a huge hallway. The floor plan discussion is already over anyway, since the shell construction starts next/next week.
The earthworks have been completed since Easter. The precast concrete slabs arrived today and the in-situ concrete will come next week. Progress is steady.
