Floor plan of a bungalow on already used land

i don't want to go through the bedroom to the bathroom

.... precisely because of that it becomes really "private", since the guest has their own shower/toilet "outside."

your windbreak would be too narrow for me as a hallway

bigger is certainly better but simply more expensive living space. - For that reason, and also with regard to your mentioned budget, the question will arise WHERE you cut something off. I think that for it is decided individually because of grandchildren, visitors, etc., so I also find it well solved. Because the open space with the gallery and the full width to the terrace pleases me and I therefore find the layout really modern. Furnishing is a matter of taste. What you probably have to watch out for is that daylight comes into the hallway area. Maybe nida also has another picture of the terrace view for themselves.

I have sketched 2 boxes for 1m, and 9-9.5m wide, inside 13m long, we have 15m long and you can put the 2m into the hallway, the supposed motorcycle️ could also fit in there

and you can get dry from the car into the house.

The topic of the utility room door in a too small utility room and hallway planning with front door, but the "I would like to enter through the utility room because then I stay dry" issue seems to come up here every week.

Think about,
- how often it rains when you want to leave the house or come home.
- why you plan a large hallway with a nice front door, only to then go through a technical room yourself
- what the technical room, which is also supposed to be a utility room here, must and should be used for, e.g., laundry washing and how the usability of drying/storing laundry fits into the process of the "second alternative hallway."

I actually also have a door (patio door) in the utility room. It is now blocked by vacuum cleaners, mop buckets, and a box of waste paper, since storage space is also available elsewhere, but the "interim storage" of the yellow bag, waste glass, and cardboard doesn’t fit into the daily rhythm in such a way that you go outside or upstairs every time for it.
In your case, besides laundry washing, the (small) laundry must also be dried – that doesn’t make it fun to contaminate the floor with dirty shoes.

I don’t want to have to walk through the living room first to get to the other rooms.

I can understand that. My example only served to reflect and zone private and open areas – I explicitly wrote about modifying, which amounts to more precise planning. For example, you could then plan the kitchen again in the west.

In your place, I would consider not having to bypass the guest area the way it is planned here. A utility room that is closer to the kitchen is more practical in everyday life and supports the idea of zoning.

Should a fixed staircase lead upstairs for you? I would plan it at least 70, better 80 cm wide so that a standard box can be safely transported there. So in a design, plan 80 cm if you include handrails and plaster.

"I want to come in through the utility room because then I stay dry" is something you feel like you hear every week here.

Just think about
- how often it happens that it rains when you want to leave the house or come home.

I see it the same way; you can create a "worst-case scenario" for any plan that then "justifies" the respective measure. I have lived very well in the house for 30 years without a garage/carport because it was converted into an office.
I cannot remember any such "worst-case scenario"

I don’t want to have to walk through the living room just to get to the other rooms.

Hm... that the bedroom comes AFTER the living room I find good, because it is then also away from the rather busy hallway. This "walking through" mostly doesn’t happen, I think you might be viewing it a bit too negatively. The bedroom door leads off the living area in a two-person household... I find that

You do have your wishes,
sketch around with pencil and graph paper, put it away and start the next one,
take it out again, correct and optimize,
the mind has to go through it.
On the way to the architect, we wanted 4 rooms, a hipped roof and a conservatory, we came back with 3 rooms, a gable roof, a kink in the gable, kitchen door and utility room door opening outwards, in summer we don’t use the front door at all. And 3 times 14 guests a year only requires extending the table. Make your house,
according to your habits and wishes

I see it the same way; you can present a "worst-case scenario" for any project, which then "justifies" the respective measure. I lived very well in the house for 30 years without a garage/carport because it was converted into an office.
I don’t recall any such "worst-case scenario"

After I had a terraced house with a carport 200 meters away and then preferred to park on the street directly on my property, I more often got wet from brushing against a wet bush. Since I have been in this forum, and as I said, the topic kept coming up repeatedly, even back then, I kept a tally for several years of how often it really rained when I came home or went out (I go in and out daily). (As a mod you have your obligations ;) ) It was in the single digits every year. Only this year did I count 12 times. That sounds like a lot? Hmm... I didn’t even get really wet because I only have 8 meters from the carport to the front door, even though I have to walk west (the weather side).

Here the house already blocks the weather side against rain. I’d say: if it fits, then you should do it, but never let the daily routine be negatively dominated by this idea if you don’t want to build 160 sqm.

The bedroom door leads off from the living area in a 2-person household

Yes, that is actually a good flow for a 2-person household.

Sketch around with pencil and graph paper,

Yes, first on paper. With a digital tool you get stuck because it takes too much effort to erase what you would delete. And repeatedly think through possible daily routines and everyday patterns.
