Floor plan help needed for bungalow

For a bungalow, a very bad layout! This is not a bungalow layout, as the "secondary staircase" is given way too much importance. Even the improvement is no improvement. I think there are many layman thoughts attached to the twisted arrangement of the rooms, which are to blame for everything somehow not being as intended.
In my opinion, the plot is also not bungalow-friendly.
But okay, if that is the wish, then I would at least ensure that living and recreation areas face south or west. More openness (for two people… over 65… you usually don’t need corridors), questioning a double garage on a narrow plot if no one urgently needs to leave the parking space in the morning.
The idea of a door from the utility room/garage doesn’t make sense because the gate is directly at the front door. A bedroom directly opposite the front door causes discomfort, a kitchen with 15 sqm and very few running meters of countertop is less than some 10 sqm kitchens.
There is still a lot of potential on the plot for a single-story house… but not for this one. I consider this design inferior and not a basis.

Living/dining room facing south/west does not necessarily have to be.

My parents are also not necessarily in favor of large windows.

The only thing is, the double garage is mandatory

We know the plot is not optimal, but unfortunately there was no better one.

They don't really care about the orientation.

My mother would like a covered terrace.

The main reason they are building is to have everything on one level.

A terrace facing east is also something they like. (Unlike most people)

And with the windows came the clear argument that they have to be cleaned too.
