The thought process was that in the original version many compromises had to be made, such as
- relocating the office to the upper floor
- removing the direct house entrance from the garage
- smaller living area, etc.
to fulfill our wishes.
Of course, the staircase design was a problem..
In this version, in my opinion, one is more flexible.
By the way, there will be no cost savings, but that was not the main focus.
