Cost points for house construction - Is there a list?

Hello everyone,

We are planning to buy a plot of land next year and want to start dealing with the topic now and be prepared when it goes ahead. Currently, we are inquiring with some prefab house providers, but the tendency is towards self-construction.

So far, I cannot estimate which service providers are needed for self-construction and what exactly each service provider does. For example, who does the foundation slab or basement and what else does this company do? Do I possibly have to arrange a crane, or does service provider XY take care of that directly? I can already imagine a lot for the heating engineer and electrician, but I think I have also heard that the heating engineer also lays the drainage pipes. The shell construction is done by masons, but what else do they do or what all needs to be done?

I hope you understand my concern. If I had an Excel list with all the points, that would be great. Ideally divided by construction phases and also with price ranges for orientation. I want to see which service provider I need first and what they do. Then I can gather information and obtain offers. Then the next service provider, and so on. Of course, there are also points like smart home that are optional, but for example, I know that this can be done by the electrician. In other words, if I want system XY, I can specifically look for an electrician who installs the system in addition to the house electrical work.

I want to use this list during construction as a checklist and cost control. In other words, what costs we have planned and how high the actual costs were.

Are there such lists? I would also be willing to pay money for it if it is really a very good list or even a program from me.

Thanks in advance :-)

Are there any general lists? Every house is somehow different: if you want clinker bricks, you build differently than with plaster. A gable roof needs a different structure than a flat roof.

Do you have a budget? Increase it by 50%. Then you have already made the most important step :)

Hello everyone, I was already expecting answers like these and although I am always very happy about receiving answers, only one response is truly constructive. Thank you !! The DIN 276 covers all cost items, but as you have correctly assumed, I am looking for a customized list. The note that such a list does not exist helps "unfortunately" ;-) I had hoped to use this as a starting point, but then it will probably be the DIN 276 along with the advice here from the forum.

Regarding the other comments... Yes, I am still relatively at the beginning, but everyone is initially ignorant or a beginner in every field. Without your advice, I wouldn’t be where I am today. I don’t want to build the house completely by myself, although an acquaintance did this. He did take longer to build, but afterward an appraiser valued the house significantly higher because an above-average quality was achieved.
I also heard about what professions individual developers had before... They are hardly ever truly qualified for the job. In your opinion, "no one" should start with this, but then I am supposed to rely on those people ;-)

That’s true, but whether clinker brick or plaster, both are done by a service provider. Keyword: exterior facade. On the other topic, I am with the carpenter and roofer. Again, regardless of whether it is a gable roof or a hip roof.

Reason?

Reason? Because 90% of builders are stuck in the "dream phase" at the beginning and in the end have spent significantly more than originally planned. I registered here in 2012.. take a look at my first posts to see what kind of numbers I was starting out with.
