Well, first of all, you don’t necessarily have to cook in a kitchen, for which I would consider 1.20m depth important (plus countertop overhang, yeah yeah). For a prep island, 1m depth is enough. The distance to the row should be 1-1.20m (let the professionals correct me), otherwise it gets too far to handle pots etc., and the sliding door is open in practice anyway. Aside from that, letting go of this island dogma is incredibly freeing (and saves the budget). Otherwise, there is currently a trend to flank islands with two rows. So a row at the top of the plan, an island horizontally, and a row at the bottom of the plan again. That might work for you too. I find it terrible, but just wanted to mention it.
