Which prefabricated house provider - prices, experiences?

So we also built a prefabricated house and are very satisfied with it! The manufacturer is Fertighaus Weiss

The plot is small. The compact house floor plan must be appealing. Optimal plots are rare. Does Par. 34 allow two full floors? Is the plot undeveloped? Find a building partner who is flexible or whose show home can be implemented 1:1.

I also have a 7m house width, the plot is roughly the same size, but not rectangular. That’s already not easy, so the children's rooms only ended up being 2.80m wide. A dimension that has partly been labeled as "uninhabitable" here. I "splurged" on 3.40m myself, but that’s still quite tight (it was only meant for me and my 1.40m bed…), so actually not a fully-fledged bedroom... The parking spaces are lined up one behind the other on the short side of the house, and there has indeed been a case where the front car had to be moved out of the way because the back one was needed... annoying.

The floor plan above resembles that of the Ideenhaus, but you shouldn’t be misled by the dimensions. However, it is certainly possible to put up a properly usable house. For me, the house length was limited to 10.5m. I have often wished that 50cm could be "added" in every direction...

What remains for me, especially due to the non-rectangular shape (it’s basically a smaller rectangle cut out at one corner), is some garden. Originally, an extension was planned there, but that would have left only about a 3m strip around the entire plot. In any case, I’m keeping my fingers crossed for your project!

Just for me as a prefab house dummy,

- Don't prefab houses have interior plaster, base slab, screed that make up the main part of the construction moisture?

I won’t go into the rest since this is not supposed to be a pro/con thread.

Are you sure you want to build a single-family house on 13x23m?
Could you please draw your mentioned desired house on graph paper where each square is 1m?

I’d be interested to see how something like that looks. Thanks
EDIT: Just saw the house dimensions. This is just my opinion but it is very likely that after deducting garage or carport and paths, driveway, terrace, etc., the garden is practically non-existent, right? Do you also need 3m distance to the neighbor when building without a development plan?

I find the budget for the house and additional construction costs OK for now!

...and I notice from your answers that you have been reading here for a while *top*

Thanks for the compliment

Yes, you still need the 3m. So we would have exactly 3m to the property boundary on each long side of the house.
We would have a 70sqm garden on the street-facing side – that is certainly too small for most people, but it’s enough for us.
I will describe the rest better when I can upload my drawing later, cannot do that here at work. But I will definitely do it by tonight.

With the given plot, I would maybe take a closer look at a local general contractor. With a setback area of 2x3m you really don’t have much house left with 13m.

87.5 sqm floor area for example. Also here: Certainly too small for many, but okay for us.

Thanks for the tip, I’ll check it out right away

Is the plot undeveloped?

Find a building partner who is flexible or whose model house can be implemented 1:1

Yes, the plot is undeveloped.
In our town and within a 25km radius, there are not only no optimal plots, there simply aren’t any at all. And I am not exaggerating. So you have to adapt, or you don’t build. Alternatives simply do not exist.

Two full floors should be feasible without problems, almost all houses around have them.

Unbuilt is cheap, unfortunately also a pity.

Before you plan too much, go to the building authority with pictures of the house and ask if it is possible. First informally. It really worked out great for us. Talked with the mayor, with the managing director, and despite §34 we have a different ridge direction and a different building line.

Thanks for the crossed fingers

I believe it’s just that in some areas you have to adapt to the possibilities if you want to own a home. Of course we would prefer a plot with 500sqm + and of course that would make things easier and of course that would be great. No one denies that. But we don’t have that option. Not now, not for over two years, and probably not in the foreseeable future (and certainly not at the price we would have to pay now). And if the children’s rooms end up being only 12sqm (just an example!), then that’s just how it is – they will survive, and if your happiness depends on the size of the children’s rooms, then we have already failed anyway.
