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

Question: Only the general contractor knows the strength of the roof? Isn't that usually determined during the execution planning?

Yes, indeed. Your planner is employed by the general contractor, isn't he? How strong the roof ends up being, of course, also depends on your wishes and specifications. Btw: Your planner has drawn 46cm walls. Under which KFW standard are we there, and is that really necessary? I mean, are there still relevant amounts in terms of the funding programs? I've been out of the loop for a while and wonder if that's really an advantage at the moment.

Forgotten in the agreements: The passage Garage - HTR/Kitchen was converted into the "possibility for short routes from the entrance." And a few more details like the large window front in the living room (partner loved that, although it might look nice, it then immediately results in full sun and thus needs shading) were also described more as a "bright living room" as indicated by rather than "there has to be a 4m wide floor-to-ceiling window front" or looking for a possibility of a shed roof for the terrace. Here too, these things seem to have simply been adopted from the previous design without further reflection.

Yes, already. Your planner is employed by the general contractor, right?
How strong the roof ends up being naturally also depends on your wishes and specifications.

No, independent architect + structural engineering office, no general contractor.
KfW40, double-shell 17.5 cm masonry + 16 cm mineral fiber insulation, 1 cm air gap and 11.5 cm facing bricks. Roof I believe is insulated above the rafters.

The question was actually whether there is currently any meaningful funding for this? Were the funding programs not mostly discontinued at some point, or was the amount rather insignificant compared to the costs? Or is it still worthwhile?

No independent architect + civil engineering office, no general contractor.

Oh really? Did you commission them yourselves? That’s a bit disappointing, isn’t it?

So the following agreements were made:
- The upper floor layout should remain as in the original post, so 2 children's rooms on the right, office north, bedroom and bathroom on the left. And the office in the north only as an option because of overheating/disturbing sunlight on the screen in the south. If there is a sensible way to avoid this in the south (except having the roller shutter down all day), the office can also gladly be in the south like in #39.

From which release version you wanted to keep the ground floor, I still do not find answered, but I will not ask for a third time either. For the glare-free monitor, a venetian blind is sufficient, you do not need to place the office out of the sun for that.

- Two sketches should be made within a few days to reach agreement on the preliminary draft. Only then make a full design again.
- The stairs should be planned with at least 16 steps with about 17/29 or maximum 18/27, and all technology within the thermal envelope.
- Then based on the sketches assemble and develop them into a satisfactory preliminary draft in 1-2 meetings, and then simply draw the whole as a complete design.
So and for some magical reason these things have not been implemented, this looks more like an internal communication problem to me (I had to wait several weeks again and have only 1 design). We still have an appointment this week, and then we will take the time for a proper preliminary draft (also thanks to the brave help of @K a t j a and @ypg).

What preliminary draft and design mean, you (but also the planner) apparently still do not understand. A preliminary design is not made once per round or extra round, but only once in one, two, or three variants in an entire house planning. Exactly one of these is chosen to be further developed, and all others go immediately and forever into the planning office’s recycle bin. All change discussions take place on this one preliminary draft, and specifically in one conference and not back and forth, gladly also over weeks, but always in dialogue (speaking against each other) and not ping-pong (turn-taking), certainly not repeatedly. And completely before from the preliminary draft (singular!) a SINGLE design is made again. From then on, there are no further designs, only corrections at most. You can find the design seminar on "Bauen jetzt", among others in "A house-building schedule, also for you: the HOAI phase model!". Of course, one can also do it differently if one has too much money/time/nerves (or wants to let a "planner" play a bit and learn). *

(most people commission a planner only up to the building application and then ask many general contractors with the approved plans, there were of course day and night offers).

One should actually still do service phases 5 to 7 with the architect after approval – but to make sense, of course, one should not commit oneself to a GC beforehand (neither at all nor to a specific one).

Question: Does only the GC know the roof thickness? Isn’t this determined during execution planning?

Katja probably meant that only the GC knows the "secret" which "wall structure" (whose thickness is relevant here) he has planned for the roof.

By the way: Your planner has drawn 46 cm walls. According to which KfW standard are we here and is that really necessary?

I also question the facing shell for the garage building body; I would have planned that only for the house and clad the garage with facing bricks.

No independent architect + structural engineering firm, no GC.
KfW40, two-shell 17.5 cm masonry + 16 cm mineral wool insulation, 1 cm air gap and 11.5 cm facing bricks. Roof insulated above the rafters I think.

Free architect, really? – I can’t believe it. That is draftsperson-level planning quality. Shame. Hopefully at least well below the table! (or even level IV because of facing bricks?)
*) In the concrete case, however, I would deviate from the described procedure, namely:
1. discard the previous designs, no longer use them as a basis for any improvements
2. declare a successful design (for example the one from Katja from release version post #86) the new and sole valid preliminary draft, only this one shall be further developed.
The recycle bin as a tool of document management is significantly underestimated!
