New building shell construction selection: Choose a company or architects?

So practically, I send my drawings with length, width, and height dimensions and request a shell construction without windows and without interior finish, with roof and covering and usable basement according to the Energy Saving Ordinance 2016?

But that only makes sense if you know that this drawing will also be approved.

Of course, additional costs will arise after the last planning and input from the structural engineer.

An architect can also be involved for the work after the shell construction.

The architect is, among other things, there to submit a building application. For the application, the structural engineering as well as the energy calculation of the house are needed. In this respect, your inquiries lack substance because you need to know with which brick and which insulation as well as which windows, i.e., U-value and so on (interaction), you have to build the house at all.
The construction companies hardly have time to provide you, as a complete layperson, with offers without a definitive plan. Such inquiries from you go straight into the circular file.

It is better to find 2 - 3 architects, choose one of them, and commission them to prepare plans and the building application. That would be a basis.
Even the calculation of setback areas is not something every layperson can do. A plot of land is also too valuable to not consider and weigh every potential as an architect could.

Basically, I consider it a bad idea for a layperson to presume to be able to read and compare these offers.

The whole thread is a cold one!

The quality of a tender stands and falls with the competence of the issuer. Those who want to save on it will get what they deserve: offers, one of which will supposedly be the cheapest.

Parallel würde ich meine Planung auch bei Architekten einreichen bzw. bei einem kostenlosen Vorgespräch darlegen.

There is no such thing as free – so who is supposed to pay for a consultation free of charge for you?

Die Architekten habeN auch die Möglichkeit in einem Vorgespräch ihre Mehrwerte zu präsentieren.

No qualified freelancer goes to unpaid castings. If you want to hold an architectural competition, the effort for the first prize must be worthwhile, and even the winners of second and third place should still receive a recognition fee. For these combined, hardly less than twenty thousand euros in prize money, you might as well simply "pay" normally.

Offensichtlich will da draußen keiner mehr um Verträge ringen, sondern nur alles leichte Kunden abfischen.

No, but no one wants to be the prey of a wannabe graphic king customer who is looking for a fool (or preferably several to choose from).

Boy, where do you live?
Lord, throw some brains down from heaven!

With such a big-mouthed attitude, you can show up around the corner if you want to have built a (long) street full of one-and-a-half-family houses every year.

Apparently, it is hardly possible to get qualified and factual answers here. A few have really put some thought into it. Thanks for that. It seems as if some here are praising the cat in the sack and recommend throwing money after everyone. Really disappointing. I expected tips here and not insults and unprofessionalism. But well, everyone wants to give their two cents even if they have no idea. "Boy, where do you live" "Wannabe graphic coke VIP customers" I thought poster Hilfehilfe couldn't be topped anymore but this guy here... well, I really wish you much success with your house construction and that you don't fall flat or have fallen flat with the very first architect. This place can close! Pure waste of time. By the way, I have already found good information in this forum under posts from others. Reading protects against rediscovery. Could do some good here. Apparently, I am not alone after all and it is normal to hold preliminary discussions before signing a contract AND to inquire about approximate costs. Really shocking how some here put down newcomers and scare them off with false facts.

Here you can close! Pure waste of time

No, really, thank you very much for the amusement. Otherwise, no one would believe that there are people with such clueless consumer self-confidence.

Certainly, you can request a shell construction, but then the price will be just as inaccurate as your inquiry. Then you have an indicator but nothing more.

You ask about the brick in your first post. Minimum requirements for the brick can be obtained from the energy saving ordinance calculation. To be able to do the calculation, many more details are needed: basement insulation or maybe none at all, window sizes, orientation, glazing, roof structure/where the insulation layer is, type of heating, ventilation system with heat recovery, ...

Since we were already talking about names above, I say dreamer!
