What can be done with a prefabricated house on your own?

Assessing yourself correctly in this matter is the greatest art. We have such experts 8 houses down the street. They bought an existing house, wanted to renovate and extend it, and had/planned to really do everything themselves. They started last year in spring and wanted to move in this summer. Currently, they are laying bricks on the upper floor walls... and the shell construction is still the smaller part.

We have also undertaken quite a lot of the interior work ourselves. On paper, it didn’t sound like much, yet I have been spending every free minute on the house construction for a year now. I am also a professional, and have carpenters and electricians in our circle of friends/family...

So just my advice: assess yourselves very critically and then multiply the time by 3.

Thank you. I can relate to that. That is exactly what holds me back a bit despite my father’s enthusiasm. The crucial point is how much you actually save. How much is it worth to you to spend every free minute on the construction site... I am very curious about appointments with solid house manufacturers..

A question to everyone: If the earliest possible time for contract signing is next year in autumn, from when does it make sense to sit down with solid house manufacturers and obtain offers? Is it too early now?

So far, Southwest House and Helma are on our list. We like a house from Weberhaus 99.999%, but they don't build stone on stone..

If the earliest possible time for contract signings is next year in the fall, from when does it make sense to sit down with solid house manufacturers and get quotes? Is it too early now?

As Lumpi_LE already says, multiply all the time by three. In that sense, there is no "too early" – that would only be the case for price guarantees.

We like one house from Weberhaus 99.999%, but they don’t build stone on stone

Then build the Weberhaus after all and change the remaining 0.01%. I wouldn’t build with Weberhaus if I was aiming for a "shell house." They don’t fit that. I would actually forget about prefabricated houses with a mason as a father. Rather, I would be a vegetarian (only the second generation non-butcher).

On our list so far are Südwesthaus and Helma.

In Hessen, I would also add Massivhaus Mittelrhein, Weton, Econ, and – although based on the floor plans of the building proposals still quite rooted in the 80s – GSE to the list.

What can you do yourself with a prefabricated house? Basically everything,... It makes sense to have the walls including windows installed and everything sealed for the prefabricated house. Everything else (electrics, plumbing, heating, floors, walls, doors,...) you can then do yourself. The electrics still need to be approved by a certified electrician and that's that. You can save money everywhere of course, but no one can say if you will actually save. Your family also needs to have time to work for you.

Once again about the budget: The bank has determined that you have a maximum of €400,000 available. But that does not match your house wish, unless you, as Lumpi_LE already pointed out, get the [Grundstück] as a gift. Shell construction in 3-4 months: that's how long professionals need, you certainly not.

Under the conditions that he also builds the shell structure himself with help, a nice house comes out of it.
Please don’t always talk everything down like that. It is a lot of work and strong nerves are needed, but please take a look at what a [Kalksandstein] stone, [Mineralwolle] and the [Klinker] cost. Then a digger driver on an hourly basis and it can get started.
But stay on it! It will be exhausting.
An acquaintance of mine also does everything through separate contracts and, for example, had the shell structure done by an acquaintance. He has been building for a year now. Masonry only on Saturdays took the longest.
I am moving with my family next week. After 10 weeks of renovation. I only handed over the electrical, windows and sanitary work. The rest with acquaintances.
It’s all possible, but it also takes a toll on your nerves.

I am amazed by the questions when you studied this subject ... no internship done?
