Floor plan 200m² single-family house, raised ground floor, existing plot, double garage

I have taken a look at the matter and can understand the architect's reluctance. The arrangement of the house with the garage leads to unpleasant and uninviting rooms. Accessing a 13m long house via the narrow side necessarily results in an insanely long corridor or, as in your case, a mega living room. The rest has to be squeezed in alongside. This leads to having 200 sqm and rooms that are either too long and narrow, too large, or too tight for their intended use. What still fits quite well at 150 sqm is no longer ideal at 200. If the orientation of the house must be this way, access should be from the east side. To make this possible, the garage must be pushed all the way to the fence on the south side. With a depth of 13.50m, this is just feasible for a garage measuring 7m x 7m.

1. Greater distance to the existing building 1.1 Terrace on the west side

1.2 Lower temperature load, because our current balcony on the south side is much too hot to stay there during the day

1.3 Warmer longer in the evening, because the sun shines on the terrace a little longer

2. The remaining lawn area is rather square and therefore better usable than a long, narrow stretch

3. Since you are rather at home in the evening, there is longer sun in the rooms because more area faces west

I see some contradictions and corsets already presented to a draft. 1. and 1.1 contradict each other: if you want distance to the neighboring building, you do not place the outer living area there (here in the west). You are not planning a balcony anyway. A terrace can also be designed to be drafty. A south terrace also gets west sun. 2. is rather more lawn area in the south if you position the house sideways. But to specify that exactly, the measurements are missing. 3. The season that benefits from west sun in the evening, you are rather busy outside. The season between O and O [East and East], the sun is not even in the west because it has already set before.

if you want distance from the neighboring building, you don't put the outer living area there (here in the west)

That was also my first thought. Plus the photovoltaic system in the west instead of the south. The heat will be almost as bad in the west as in the south, since the southern sun also blasts onto the west side. If you want a shady spot, this plan is definitely not the solution. What is also annoying is the endlessly long wish list that they want to squeeze onto 2 floors. The planner has already hopelessly placed the technology in the garage on the ground floor, and what's going on on the upper floor doesn't even need commenting anymore. Everything is supposed to be huge as well. Basically, that's okay if you can afford it. But if the space is limited in area and you also need a 7m wide garage, then the idea naturally moves to the 3rd floor.

2. what does the architect do professionally,
3. why are you showing his plans redrawn instead of the original, and

Architect with 40 years of experience and at least for the objects not an artist.
I don't have a plan where I can find the current exterior dimensions with garage on the property again. I have only received the design for the interior so far.

You want to build 200 sqm and then it fails because of money for a kitchen island?

Well, somewhere you have to cut costs and I find a kitchen island more "showy" than useful. And I don't want to spend money on showy things.

I took a little look at the matter and can understand the architect’s reluctance. The arrangement of the house with the garage leads to unsightly and uninviting rooms. Accessing a 13m long house via the narrow side inevitably results in a crazily long corridor or, as in your case, a mega living room. The rest has to squeeze in beside it. This means having 200 sqm but rooms that are either too long and narrow, too big, or too tight for their use. What still fits quite decently at 150 sqm is simply not ideal at 200.
If it absolutely has to be this orientation of the house, the access should be via the east side. For that to work, the garage must be pushed all the way to the fence to the south. With a depth of 13.50m, just barely possible for a 7m x 7m garage.

Thanks for this constructive contribution. Now I finally understand what the problem is. Really, thanks again!
We had discussed access from the west side. Then the main entrance of the existing house would be opposite the new building. The architect discarded this with the reasoning:
Entrance not directly visible → people get confused when they enter the property
Entrance is hidden → you just don’t do that
People walk towards the light → entrance in the west doesn’t make much sense

Regarding the house orientation itself, sure, that was my idea. I have already named reasons, but that doesn’t mean I won’t be convinced otherwise if there are reasons.

I see some contradictions and preset corsets for a draft.
1. and 1.1 contradict each other: if you want distance to the neighboring building, you don’t place the outer living area there (here to the west)
You’re not planning a balcony anyway. A terrace can also be designed to be drafty.
Even a south terrace gets west sun.
2. is rather more lawn area in the south if the house is placed crosswise. But to fix it exactly, the measurements are missing.
3. The season that benefits from the west sun in the evening is when you are usually busy outside. The season between O and O (east and east?), there is no sun in the west at all, because it has already set.

I find there is a difference whether I consciously stay on the outdoor living area where I am freely visible, or in my own four walls, where someone looks through the window.
I am trying to get the measurements ... even if you don’t believe it, I am really trying very hard...

That was also my first thought. Plus the photovoltaic system on the west instead of the south. The heat will be almost as bad in the west as in the south, because the southern sun also hits the west side. If you want a shady spot, this plan is definitely not the solution.

What is also annoying is the endlessly long wish list that you want to squeeze onto two floors. Out of desperation, the planner has already put the technology in the garage on the ground floor, and what is going on upstairs doesn’t even need to be commented on. Everything is supposed to be huge as well.
Basically, that’s fine if you can afford it. But if the space is limited and you also need a 7m wide garage, then the idea naturally goes to a third floor.

Well, you have many wishes, and I don’t think it is wrong to express them, because maybe there are ways to integrate them all. But until now, no one has said where the problem areas are. Of course upstairs the number of rooms is a problem, but that’s why we thought with 100 sqm area it can be tackled.
Now I have also learned why there are problems with an entrance on the narrow side ...
I hope you understand what I mean :)

We had discussed the development of the west side.

That would really be absurd here.

I think there is a difference whether I am consciously on the outdoor seating area, where I am freely visible, or in my own four walls, where someone looks through the window.

It is always easier for everyone involved to make suggestions when you understand the motivation. Who exactly is not supposed to look through the window now? I assume the neighbor to the south?

I am trying to get the measurements ...

The best thing is to go to the property and roll out the 30m tape measure. You especially need the measurement from the path to the south fence.

Who is not supposed to look through the window now? The neighbor to the south, I assume?

That is meant ironically, I assume? Maybe also a hint that you are simply better off with a south-facing orientation including photovoltaics and windows facing the field.
