For heaven’s sake, I can’t read it anymore.
I frequently deal with tenders professionally. Do you have any idea how much effort we put into bids without even knowing if we’ll be awarded the contract or how many other companies are also submitting offers?

That’s exactly what I wrote: a client should make it clear to those they contact whether they are among those for whom the effort is reasonable. Simply following up a request email with a call, to briefly get to know each other, significantly increases the response rate. Especially since you’re usually on the other side, you should already understand this.

It has already been mentioned here several times that building a house is the biggest investment in life

All the more reason to put yourself in the shoes of the request recipient once in a while.

I would like to have a broader overview of the market and pricing.

Some clients interpret this as meaning that eight offers are better than "just" seven (which are already too many and indicate desperate mass inquiries). If the bidder fears dealing with someone like that, they—unless they are desperate—won’t submit an offer at all.

In Stuttgart Stammheim, in the new development area of Langenäcker Wiesert, around 100 new houses are being built on 8.8 hectares (22 acres). Every day, a different contractor is digging a foundation. Several houses are already completed or nearly finished. You can clearly see from the shell constructions what a solid masonry house and a prefabricated house look like.

My opinion: Anyone who buys a prefabricated house, no matter the provider, must not be thinking clearly. It’s timber framing with gypsum boards and bologna sausage with fiberglass insulation. It’s unbelievable that people spend so much money on such low-quality building material, sometimes even without a basement, simply unbelievable. They sell you on the idea that it saves time, but fail to mention that the interior finishing takes roughly the same amount of time as for a solid masonry house. A shell construction including basement nowadays takes 4-5 weeks to complete. Who in their right mind would buy a prefabricated house for nearly the same price, when the entire house weighs as much as the foundation of a masonry house? Whether it’s Weiss, Okal Haus, Beilharz, or Bien-Zenker, it’s all equally worthless. Even Bien-Zenker won’t help you.

Very well-founded and meaningful contribution, Stuttgart0711. Your choice of adjectives shows how thoroughly you have dealt with the different construction methods. You probably write Amazon reviews with comparable expertise as well.

@Hous: The choice of adjectives is completely irrelevant here, I have spent nearly 18 months studying this in detail. I am currently building a house that I designed myself, selected all the materials, and am largely managing the construction myself, even though there is still a “real” site manager. My neighbor built a prefabricated house with Weiss next to me, and it doesn’t even have a basement. The construction time from the foundation slab to moving in was 8 months.

Two houses down, another prefabricated house by Beilharz is being built, and next to that one by Okal Haus. I visit the site every day and see — or rather have to witness — what people are putting up with, due to lack of knowledge and fear of alleged insolvencies linked to solid masonry construction. At the Fellbach sales center, customers are mainly presented with one argument: everything is fast (house ready in three days) and everything from a single source. Many accept this, assuming it really is much faster.

What is delivered is basically the same regardless of the provider: prefabricated timber frame elements, pre-installed windows, tongue-and-groove systems, lots of insulation, plywood, and above all, huge amounts of drywall panels for the interior finishing. The perceived quality can be felt, seen, and even heard. One thing all providers have in common is that if someone wants to break into one of these houses, they just need to kick in the wall in the middle — and they are inside. You just can’t do that with a 36.5cm (14 inch) brick wall.

Attached are some pictures. What would you say has greater lasting value or higher mechanical strength: cardboard with pressed wood walls and bologna, or 24cm (9.5 inch) concrete walls in the basement and monolithic construction with bricks or other stones on top, 15cm (6 inch) sand-lime brick walls, and cast-in-place concrete ceilings? Incidentally, the houses cost roughly the same to build.

Please don’t degrade me to a talker who doesn’t know what he is talking about.

There are different philosophies regarding the optimal wall thickness of external walls. Some recommend 36cm (14 inches) or more, others find 30cm (12 inches) sufficient, depending on the building material and insulation concept. The main goal is to achieve a balance between structural stability, thermal insulation, and cost efficiency. In some cases, thinner walls with high-performance insulation can outperform thicker walls with conventional materials. On the other hand, very thick walls can offer better sound insulation and thermal inertia.

When planning your house, always consider the local climate and legal requirements such as building permits / planning permission. It is also important to look at energy efficiency certifications that may influence insulation standards.

If you want to discuss specific construction methods or materials, please provide details about your building location, climate zone, and preferences for wall materials and insulation types.

User Hous8au may have valuable experience related to this topic.

There are different approaches with various solutions. In the end, the results should be evaluated (thermal insulation, soundproofing, structural strength) against the specific requirements, which can vary greatly depending on the builder (mechanical strength of a bunker, regional factors, sustainability, cost certainty, etc.). The time argument is currently irrelevant, as you surely know from your 18 months of research. Security evaluation includes both burglary protection and fire safety. In both cases, this depends not on the construction method but on the materials used and how they are installed, so no generalizations can be made here either (for example, polystyrene insulation or the security rating chosen for doors and windows). The decision for or against a basement is also independent of the construction method.

Finally, the outcome is influenced not only by the construction method but also by many other factors such as design, planning, and especially execution. Regardless of which electrician (electric company or general contractor, whether concrete or timber construction) connects the wiring incorrectly, it makes no difference and leads to errors in both cases.

Based on the points mentioned above, I find your opinion unsubstantiated, too generalized, and absolutely unhelpful for people like the original poster or others facing the same issue and looking for objective assistance.
