I have been thinking about a good floor this weekend.
I still intend to use a floor like this:

The easiest way to have the studiofloor decoupled from the rest of the building would be like this:

This comes with no cost adder. However, the foundations are shared, and therefore there is a flanking path from one floor to another: floor1 surface -> Tbeam floor 1 -> common foundation Tbeam floor 2 -> floor 2 surface. This technique is used for townhouses/terraced houses.
Bert suggested earlier that a decent floor should have a separate foundation. So the second option is this:

This option comes with a cost adder in additional concrete for the foundation beams, and some additional piles. Also, it is a bit more difficult to build. I have limited real estate, so the distance between the foundations must be very small, I took 4 cm in the drawing. Therefore I think I cannot pour both foundations in one go. On the other hand, I like engineering challenges
Is there any way to predict the difference in TL with the two options? I think option 2 will cost me about 2k euro's more, so it would be nice if I could justify this cost.
