Floor plan access from kitchen to pantry / storage room

but rather like in the 3D visualizations.

Considering that yellow bags are also stored there, possibly also beverage crates, the 80 cm between the island and the tall cabinet should perhaps be slightly increased. The kitchen is a bottleneck, and then it leads into the enclosed pantry.
The counter is also a bit shallow in depth.
maybe the 2nd of the 4 variants after all? That way you would gain a few centimeters as a passage and wouldn’t disturb the person cooking dinner when taking out the trash.

Look there at the finished kitchens, climbee has such a door and others. Ask in the subforum "Küchenmöbel".

Decisive is the kitchen width, which you have not mentioned.

It is good to avoid corners, i.e., in your case an L + a tall cabinet row at the top of the plan would be ideal.
Calculate the room width minus plaster trims on the right and left of the tall cabinets (at least 2cm each), the depth of the base cabinets is just under 60cm.

Just make a door/sliding door on the entrance side as well. Then you have access from both sides. It doesn’t get more practical than that!

Stupid question, but why have a pantry at all? With such a small kitchen, I would rather remove the wall and plan for more cabinets – more workspace and a more suitable counter. Side by side fridge and the yellow bag in the garage.

Mainly for drink crates, vacuum cleaners, and other bulky items (e.g. vases, toilet paper, paper towels, [Thermomix] that one doesn’t need daily, etc.). For supplies alone, a medium-sized kitchen would certainly be sufficient.

Exactly for that. We also have a freezer in there. A wine rack will also be added :).
