I have the info now, but smarter than this morning I am not because of having the info now.
This is due to the following:
We did not do any storage planning because the current kitchen is smaller.
With that, everything you could gain as an advantage from the 6-unit grid is not present.
The point is that the 3-drawer units, which are often planned (drawer - 2-drawer pull-out, 3-drawer pull-out in your case) are much less useful than you might think. This height is needed for large bottles (vinegar/oil, water/beer crates) and large pots. Everything else is then stacked into these funny multiple stacks again to use the excess air space, and you have to unstack every time to get to the bottom. At the same time, you have lots of small stuff lying around (in deep pull-outs or in the famous storage can on the countertop) because normal drawers are missing.
It all still works. Ergonomically far from optimal though.
That raises the question about usage behavior. For heavy users of a kitchen like me, it would be a no-go to spend that much money if I had to accept such circumstances. The priorities there seem a bit strange to me – whether I get enough kitchen for the money (which was your question) does not depend only on the cubic meters enclosed by cabinets?
Others will not be bothered by this at all. Only you can know that. Just as only you can know whether the counter attachment is needed. From my experience, that is purely an optical gimmick that annoys more than it helps. You can sit on stools at the countertop as well, but without the counter you can do even more (working on both sides, for example), which the counter prevents. A seating counter at stove and extractor hood is a fail for cooking, especially frying. Unless the island is 1.2m wide.
You live in an open space and the dining table is right around the corner. My crystal ball says: Coffee will rarely if ever be drunk there, eating certainly not. Of course, no guarantee.
As I said, personally I would follow Kerstin’s suggestions because that is structured more sensibly. I would also have fewer 3-drawer units and instead zone 1-1-2-2 drawers in the 6-unit grid. But I would never have set your kitchen budget without thinking it through first – no offense. There is really enough other stuff to do when building a house.
The forum is like the floor plans here – after reaching the Pareto optimum, people keep fine-tuning the last 20% intensely. Legitimate, and it should not be mistaken for the fact that no kitchen ever pleases anyone.
What the kitchen fitter offers as standard is often simply not very ergonomic and sensible once you know what really works.
