Terraced house near Stuttgart, need support

Yes, what can I say, you're right.
We are now right in the middle. Financing basically clarified very worst case scenario. So check.
We are now becoming more and more concrete, it is really amazing what we had not thought of yet.
The floor plan is also taking final shape.
We are working on a kind of building application folder so that when we are ready, we can really get comparable offers.
But what is really crazy is to distinguish what each house builder offers you.
What and how detailed. Here an Excel table is probably needed to be able to differentiate and a lot of construction and service descriptions have to be read.
Just trying to compare the wall structure in timber frame construction or to find information on the internet is incredibly time-consuming and practically impossible.

Currently, this is our project:

What is still missing?
Where can money be saved?
Carport yes, will probably be a kit.
Photovoltaic system?

I come from the software industry and am basically familiar with the process. And I also believe that you actually do the process differently than you are doing right now.

No, that's roughly fine. Especially currently again.

Everyone basically has an interest, because they want to sell you something and make money from it. Just the fact that everyone has a bunch of representatives sitting in model houses should be proof enough for you.

In fact, some, especially solid construction companies, have no interest in cooperation. Either no capacity or they don't build in infill plots or no one gets back to you anymore.

We are working on a kind of construction application folder so that, when we are ready, we can really get comparable offers.

What expectations do you have about how deeply the providers are willing to dive into the challenge of a casting?

But what is really crazy is to distinguish what each house builder offers you.
What and how detailed. Here an Excel table is probably needed to be able to differentiate, and a lot of construction and performance descriptions have to be read.

The Excel table would already have to be built like a Falk plan. Freely after Shakespeare: Sisyphus, Pyrrhus or Varus – that is the question here. You don’t read the best construction performance description, you write it.

Just trying to compare the wall structure in timber frame construction or trying to find it on the internet is incredibly time-consuming and almost impossible.

As pointless as I find it otherwise, in this specific case I see the timber frame panel builders all hardly interested or desirable. Look around with the regional masons. I generally see this project hardly suitable for amateur tendering, no matter how fearless one is ready to grasp the windmill wings. An architect is needed here.

Does it make sense to inquire about the basement yourself?

No. It is only the beginning of March, and yet I have already said this several times this year. Opening the interface OKKD as a flank for games of black Peter regarding the responsibility of fitting together is the sister of cutting down the sums.

...
Photovoltaic system?
...

From May, the obligation for photovoltaic systems applies in BW, so presumably this question is no longer relevant. However, it would be interesting to see how the individual general contractors handle this now. Can it be easily removed and installed by oneself (as long as the scaffolding is still up and the house has not been accepted yet)? Or do some cause trouble? Photovoltaic systems are generally very, very expensive through the general contractors.

What are your expectations regarding how deeply the providers are willing to dive into the challenge of a casting?

Well, the hope that dies last is that we get comparable offers.

The Excel sheet would have to be built like a Falk plan. Freely after Shakespeare: Sisyphus, Pyrrhus or Varus - that is the question here. The best construction service description is not read, but written.

I had to google what a Falk plan is first :) That roughly reveals your year of birth :)
Well, the level of detail is of course open upwards but maybe for an overview. It’s at least better than having 5 such booklets side by side. The best construction service description is written? Yeah, that may be so but so far I have only been actively in contact with timber prefab builders.

As pointless as I usually find it, in this particular case I see the timber frame panel builders hardly interested or desirable at all. Take a look at the regional masons. I generally see this project hardly suitable for an amateur awarding process, no matter how unafraid one is to grasp the windmill blades. An architect is needed here.

Why do you see the project as demanding and why an architect?

An architect just for planning or also to hire him?

Is masonry better than timber framing? You really can’t say that, can you?

I am already further with the timber framers because, unlike the masons I asked, they didn’t immediately decline or quote extremely high prices per sqm --> Fermo.

In the forum you can still find masons in my region to inquire with and I will do that, however I just haven’t had any luck whether with Heinz von Heiden, Viebrockhaus, Fermo, Böpple, Krämer, or smaller ones like Bürkle, Pfeil, Otto-Bayer. Only Schneider Bau in Esslingen has not ruled it out yet. I made an appointment there over a week ago for mid-April!

Are there threads you haven’t read? :)
Are you an architect yourself?

No. It’s only the beginning of March, yet I have already said that several times this year. Opening the interface OKKD as a flank for Black Peter games regarding the responsibility of fitting together is the sister of shortening sums.

I had to read that sentence twice but thanks, then the topic is off the table.

From May, the obligation for photovoltaic systems applies in BW, so this question presumably does not arise. It would be interesting how the individual general contractors handle that now. Can it simply be removed and installed by oneself (as long as the scaffolding is still up and the house has not yet been accepted)? Or do some cause trouble? Photovoltaics are generally very, very expensive through the GCs.

Yes, that’s why as an option. I also think photovoltaic ready is sufficient and the photovoltaic system from someone else.

But then that already goes in the direction of not all from one source, which was important to us at the beginning. Where do you start and where do you stop?
Photovoltaic system not from the GC
Carport a kit

Painting and plastering do it ourselves and suddenly we do what we didn’t want :)

Hoffmann dies last, I always say that too. But I deal professionally with tenders and know that Excel spreadsheets are THE tool of the preliminary decision-makers. I was born in ’78. I’m not an architect, but a construction pilot after interesting detours. Thanks to my elephant memory, I remember well what I once read. There is a whole section here, especially in the form of financing threads, in which I have read almost none of the threads – otherwise almost all since I have been here and looking back about a year at that time.

Die beste Bauleistungsbeschreibung schreibt man? ja das mag sein aber bis jetzt bin ich nur aktiv mit Holzfertigbauern in Kontakt.

What is that supposed to have to do with the construction method?

Wieso siehst du das Projekt als anspruchsvoll und wieso ein Architekt?
Ein Architekt nur zum Planen oder ihn dann auch beauftragen?

If a middle terraced house in an infill site is not a demanding project, then enlighten me! An architect plans, details, tenders, and manages construction. The client then commissions the bidder(s) based on the architect’s recommendation according to the tender results.

Ist Stein besser als Holzständer? Kann man doch so gar nicht sagen oder?

Exactly, you normally cannot say that, because due to their equivalence despite differences, it would be wrong. But in a terraced infill plot, as a construction pilot I do not see a prefabricated house floating in—no matter if the wall panels were stone or timber frame construction—but rather a masonry house must be fitted in. For the same reason, I would also see a carpenter-built house there if the neighboring buildings were wooden.
