130 m² bungalow for 2 people

Here are my comments.

The planned room is 540cm deep plus about 10cm more in the area of the patio doors.

The wall line on the left side is about 60cm deep, minimum aisle width 110cm, island minimum 90cm deep, leaving 290cm space for table and chairs.

If you calculate 90cm depth for the table and 60x60cm per chair, the space is sufficient. If you sit like we do at the narrow ends of the table (when there are two of you), the passage between the patio door and table is enough if it is a sliding door.

It is nicer if the island could be 100cm deep and the aisle width 120cm, the latter because of age.

Drawers extend 45cm into the room, an XXL door 64cm, HS doors 60cm. These distances should be tested, either in the current apartment/house or with boxes.

Because it protrudes too far into the room, the island cannot be longer than 280cm (including end panel/cover panel) so that the passage at the kitchen entrance is at least 90cm. The island would be a bit short for the cooktop and sink. 310cm island length (including end panel/cover panel) would be better, for that you would have to shorten the corridor wall by about 40cm.

this is an island 3m long, 90cm deep plus deck side/cover panel. The corridor wall is shortened to have at least 90cm distance between the island and the corridor wall.

The door properly [Schlafbereich] makes it very impractical and uncomfortable
