ᐅ Cost Factors for Building a House – Is There a Checklist?

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 :-)

PS: we originally had 500...600k in mind. Current status: 1.14 million (all in, including expensive kitchen, costly garden, expensive land, etc.) and still not living in 🙂

That’s already on the level of the public sector ;-)

In other words: not the norm for private home builders.

Not necessarily. Years ago, we were confident that with under 300,000 we could get our dream house including the plot. There are those colorful brochures everywhere starting from the top of the foundation slab. Turnkey doesn’t necessarily mean that a moving truck shows up, and that there are additional construction-related costs, plus that some houses, for example, offer electrical installations from around 1955—well, we had to learn that too.

Comparing the actual final price with the misleading, bait-and-switch marketing price is like comparing apples and oranges. “Illustrations may show optional extras” is something we already know from car brochures; it shouldn’t be surprising when it happens with houses. If the construction specification states that there is a ceiling light outlet in the center of every room, and in the kitchen you already need a triple socket extension for the toaster, then the obvious result is: the house will cost more than “starting from $199,000.” If the plot has rocky or sandy soil, the foundation work becomes more expensive. But that is not inflation.

The detailed scope of work is usually unknown when you are at the stage of “look, the house only costs this much.” Additional costs are already clear, but for most people, “turnkey” initially means just moving in, not simply having the front door installed.

There is a huge difference between that stage and receiving the first realistic offer.
