Hello from the north,
we have been offered a quite interesting plot of land. The seller demolished an old house on this property but left the basement floor slab at a depth of about 3 meters (10 feet).
We do not want to build with a basement. Will this floor slab cause any problems for us? Does the old slab need to be removed? Should we possibly consider a special foundation?
Thank you very much in advance for your answers.
Best regards
Henrik

The area was filled in above. Good point about requesting photos, thank you. Attached is our site plan. In the background of the drawing, the old house can be seen with transparency. Without transparency is our planned house.

Site plan of a property: House with carport, plot 22/23, dimensions and outline.

If the area has already been filled, I would conduct a plate load test. This way, you can verify whether proper compaction was done and not just the top centimeters.
