Floor plan single-family house 1 full floor technology and daylight

There it is again: the NoGo wall. But honestly? You can do without it here.

So here is the latest draft. Actually, we had said to leave the upper floor as before, but alright. As for the ground floor, I'm not sure.

Which "before" - post #27? The house connections would have to be made in the utility room; in the technical room, the problem of being built over would arise. The chicken ladder to the attic is more uncomfortable to climb than a pull-out ladder - at least for shoe size over 29 [hheh]. Should the designer only improve the degree to which you like the floor plan (and may sacrifice all other planning quality features for it), or how does this, I would say, bad planning come about?

Yes, I could cry

Which "before" - post #27?

"We" = architect and us. The architect had suggested creating 2 sketches of the ground floor (without many details), and leaving the upper floor as it was in the previous design (except for the stairs to the upper floor). Now I only have one design with all the details.

The chicken ladder to the attic is more uncomfortable to climb than an extension ladder - at least for shoe size 29 and above

The attic stairs are rather secondary at the moment, our folding one has about ~12 cm tread depth, so 23 cm should be more comfortable. It’s probably intended as a space-saving staircase.

The house inlets should be placed in the utility room, putting them in the technical room would cause a problem with overlapping.

What overlapping, technical room? The tech goes in the utility room (so not at the back in the garage, although it is still drawn there), we already discussed that.
What I don’t like spontaneously is the entrance to the cloakroom and guest WC going through the entire hallway and around the corner. Also, the island might be tight, if I calculate correctly, it looks like 4.52m including outer wall, so with 1.20m distance to the wall only 1.66m remains for the island with just the cooktop. Hmm. So honestly, this doesn’t really warm my heart.

Is the planner supposed to only improve the degree to which you like the floor plan (and may sacrifice all other planning quality features for this) or how does this, let’s say, bad planning come about?

Maybe it’s the synergy, as already pointed out. So far, we have never drawn and discussed together in the same room, but I was always only allowed to "review" what the technical draftsman put together (of course already with our room program).

Are the 9.50m ridge height in the architect’s plan fully utilized? Is there a section for it?

As you can see, almost fully utilized at 45°.

In the meantime, I had tinkered a bit more with the draft. I'll post the latest version.

Without the staircase to the attic, you could probably build noticeably smaller without significantly losing living quality.

Well, I would forego the conservatory and rather just continue the wall. What I’m really curious about, though, is how the office would fit facing north (e.g., above the entrance) and what size it would then have. I can’t imagine sitting there all day either in full sun or completely darkened in the south. Do you mean "noticeably smaller" because the staircase in your plan just continues into the attic? I can imagine that.

"We" = architect and us. The architect had suggested making 2 sketches of the ground floor (without many details), and leaving the upper floor as it was in the previous design (except for the stairs to the upper floor). Now I only have one design with all the details.

My question was then which version of the design was meant by this "previous", how you thought to leave the ground floor.

Maybe it’s due to synergy, as @ypg already noted. Until now, we have never drawn and discussed together in the same room, but I was only allowed to "review" what the technical draftsman had put together (of course already with our room program).

What kind of superstructure, technical room? The technical equipment goes into the utility room (so not at the back in the garage, although it is still drawn there), as we already discussed. What I don’t like spontaneously is the entrance to the cloakroom and guest WC through the entire hallway and around the corner. [...] So honestly, it doesn’t warm my heart at all.

The corona lockdowns are over, no one has to do video conferences with their planner, and especially not a ping-pong of misunderstandings. By the superstructure I meant that house entries below the garage floor into the heating closet behind the garage would be covered by the same superstructure. If this is already clear and the planner still draws a completely different world, that will at the latest cause trouble during execution. Nobody needs plans that force the executors to improvise from the start (which the subsequent trades do not know about and try to connect to the plan status).

Yes, I could cry

No, don’t cry, but roar (the planner flat out into the ground), so that his obstinacy goes away. A wall that feels like a no-go for you is only the tip of the iceberg, I already see a (see forum search) "butcher house" coming. I see an array of thoughtlessness here (and I also take my warning about the chicken ladder cellar stairs seriously). Ladder rungs and stair treads cannot be compared. When the botch is built, you will wish you had chosen the "worse" variant. Change the planner, that will be the highest-performing investment of your life. Has he even ever seen what counter-proposals, for example, Katja made? With patches you won't get far. There must be agreement on the preliminary design before it is further distilled into the design.

As you can see, almost maxed out at 45°.

Nope, 7 cm are missing at the knee wall and you would still have a full 37 cm up to the ridge. But okay, that’s not crucial for an initial idea. I don’t find the design totally terrible now. You’ve already mentioned some points yourself. What bothers me most is the main staircase; a 19.5 cm rise must be a joke. Adding one more step to a staircase often doesn’t work well – it should fit perfectly from the start. We already discussed the stairs to the top. With the statement

DG stairs are rather secondary at the moment,

you’re not helping anyone. Make up your mind! Is that okay? How exactly should the access to the top be designed? It wasn’t shown again. Should there be a door before it downstairs or how should the thermal separation be accomplished? Do you want to always heat the entire attic? That can’t be the case, right? Without clear instructions, you won’t get a meaningful result.

What I’m really curious about is how the office would fit in the north (e.g. by the entrance) and what size it would then have. I can’t imagine sitting there all day in full sun and completely darkened in the south.

The rooms upstairs are already quite clearly divided. If you move the office to the north, only the south remains for the stairs. Then they would be downstairs in the living room. That would be bad. You could try playing around again with a horizontal layout... no idea if that makes sense.

Do you mean "noticeably smaller" because in your plan the staircase is simply extended into the attic? I can imagine that.

I think I already mentioned that you probably make better use of the space with a folding ladder at a hatch to the top. However, the chicken ladder in your planner’s design is already comparable.
