Bungalow floor plan design - ideas?

I have circled the unnecessary corners here...

I am fully aware that this is no longer a classic corner bungalow.

?? It is a classic corner bungalow - just not with the well-thought-out orientation to also design a house corner as a cozy oasis.

Which wall do you mean with the two doors?

I mean the imaginary wall above the hallway with the bedroom and guest room doors.

For example, I could imagine swapping the corner storage room, utility room, kitchen, and living room, but how???

It's not so easy to fit the area with rooms, some rooms are still too small for him. However, I didn't want unnecessary traffic areas either. Everything has to be maintained.

The rooms are not too small. They are decent sizes!
I think thinking about good planning NOW AFTER the building application is too late.
You are going in circles – this discussion has already happened, and I actually miss your arguments why this or that has become the way it is now. Instead, it is now said:

Currently, I have reached the point where nothing works anymore. The planner apparently doesn't understand me, so the plans go back and forth several times before anything changes at all.

Today I will enjoy my Sunday and try to clear my head of deadlocks.

The deadlock can be seen quite well here, in your starting plan:

The guest room did get a different place at least, but otherwise the living room remains a trapped room.

You have already received some good approaches here, back in April! Planner or not. Kerstin had good approaches... and every household must create rooms that must serve as storage space (or in your case commercial use). Some in the house, others at the garage or as an intermediate building section. However. Deadlocked means being unable to free oneself from the orientation.

If it weren’t sad, one could be amused about it, but you are sinking several hundred thousand euros into the property. There is no going back once construction starts.
Therefore, be critical of yourselves and take the kitchen planning, which is already not working, as a reason to change the basics.

So, and now sketched into the site plan. Garage with utility room indicated with external dimensions of 7x9 m.

I prefer your approaches from ##21,22 from April... and somewhere you could still fit in the commercial space

Basically, I like the Swedish version: the living area in the middle, one wing for parents and guests, the other wing for children and commercial use. Comes with a 5 sqm entrance hall and a mini corridor for each wing.

.. basically for me too, basically for me too. But I wanted to keep the requirements here like "children's room, children's bathroom, and guest room together and possibly separable."

And, probably a very important requirement, the position of the house connection room, because that's where all the utilities somehow come in. I have roughly kept the position. And I simply don’t know enough about what could be moved elsewhere advantageously.

And, probably a very important specification, the position of the house connection room, because somehow all the utilities arrive there. I have roughly maintained the position now.

What specifications were there, Kerstin? I somewhere didn't pay attention and overlooked it

Said to be effective sometime, I believe since yesterday and on page 6. I had also asked whether relocation has already been checked, but no explicit answer to that.

I thought so, connections from the street side, not from the alley...

But you could also place commercial areas in the east, where later the access to the garages will be.

Oh... sigh... there was and is enough input.
