Hello everyone,

We are planning to buy a plot of land next year and want to start familiarizing ourselves with the topic now, so we are prepared when the time comes. At the moment, we are looking into several prefab house suppliers, but we are leaning more toward self-building.

So far, I’m not sure which professionals or contractors are needed for self-building and what exactly each of them does. For example, who is responsible for the foundation slab or basement, and what else does that company handle? Do I need to arrange a crane myself, or does the contractor take care of that? I have some idea about the heating technician and electrician roles, but I’ve also heard that the heating technician might install the drainpipes. The shell construction is done by bricklayers, but what else do they do, and what tasks still need to be completed?

I hope my questions make sense. It would be great to have an Excel sheet listing all the points, ideally divided by construction phases and including price ranges for reference. I want to understand which contractor I need first and what services they provide. Then I can gather information and get quotes, followed by the next contractor, and so on. Of course, there are optional aspects like smart home systems, but I know, for example, that these are installed by the electrician. So if I want system XY, I can specifically look for an electrician who handles both general house wiring and that system.

I also want to use this list as a checklist and cost control tool during construction. That means comparing our planned costs with the actual expenses.

Do such lists exist? I would also be willing to pay for a very good list or even a program if it is comprehensive and useful.

Thanks in advance :-)

How well do you understand the individual trades or do you have someone with a basic knowledge of plumbing, electrical work, etc., to assess the quality of the contractors' work?

Without meaning to offend you, your text suggests you might not have a lot of experience in this field. Planning and managing everything yourself is probably not the right approach.

Contact a company that offers turnkey construction and ask for a detailed scope of work (construction scope). You can then review it carefully and have it checked, so you will know exactly what else is needed.

For an architect, this is routine, and the methodology is the same whether you hire tradespeople or plan to do the work yourself.

Both prefab and traditional masonry home suppliers often offer shell homes—or options between the basic shell and fully finished homes. For someone doing this for the first time, this is usually a better approach than trying to do everything on your own.

Building a house nowadays is not as simple as a children’s story where you just stack bricks and only need diligence and skill. For example, installing the thermal break (Isokorb) on the canopy cantilever is not something you can just learn from a YouTube tutorial. ;-)

I believe he means self-managed construction rather than self-built, and with the current level of knowledge that could already be disastrous.

You can find cost item lists according to DIN 276 online for a low price.
What you are looking for is a customized list (a combination of a project schedule and a breakdown of trades/costs).
I haven’t seen anything like that here.

Are there general lists available? Every house is different in some way: if you want brick cladding, the construction differs from using render. A pitched roof requires a different structure than a flat roof.
I also believe your questions speak volumes: you should really have a professional handle this. It’s quite different from managing a garden shed project.
Hardly anyone here would dare to take on this kind of work, and if so, it would usually be someone with a background in civil engineering or a related field.
