This kitchen layout accommodate an integrated island and dining table, in a linear shape. The dining table can host 6 people / seats during usual days, but in case more seats needed, the island can be transformed into extended dining area, by putting extra chairs. The chairs would be stackable wooden stool type, something simple and compact like this:
If not needed, the stools can be stored in a cabinet/wardrobe and stacked.
The rest of the design is self-explanatory (please refer to the drawings, material/finishes & furniture selections, and 3D renderings).
Thank you very much and all the best with your home project.
