Construction company wanted in the Stuttgart metropolitan area!

God, I can't read it anymore.
Professionally, I often deal with tenders. Guess how often we put massive effort into bids without even knowing if we’ll get the contract or how many other companies are also bidding.

That’s exactly what I wrote: that a client should make it clear to those asked whether they belong to the group for whom the effort is proportionate. Simply following up the inquiry email with a call to briefly get to know each other significantly increases the response rate. Especially if you are usually on the other side, this should be clear to you by now.

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

All the more reason to take the time to put yourself in the recipient’s shoes.

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

Some clients then interpret this as eight bids being better than “only” seven (which are already too many and show helpless mass sending). If the bid recipient fears dealing with someone like that, they won’t submit a bid in the first place—unless they belong to the desperate.

In Stuttgart Stammheim in the new development area Langenäcker Wiesert, about 100 new houses are currently being built on 8.8 hectares; every day another one comes and digs a hole. Some houses are already finished or almost finished. You can clearly see from the shell constructions what a solid house and a prefabricated house are.

My opinion: Anyone who buys a prefabricated house, regardless of the provider, cannot be entirely sane. It is timber framing with gypsum boards and meatloaf with glass wool. It is unbelievable that people invest so much money in such inferior building material, sometimes even without a basement, simply unbelievable. You are sold time but it is kept quiet that the interior construction takes about as long as it does for a solidly built house. A shell construction including basement nowadays takes 4-5 weeks; who is so foolish to buy a prefabricated house at roughly the same price where the entire house then weighs as much as the foundation of a solid house. Regardless of Weiss, Okal Haus, Beilharz or Bien-Zenker, it is all equally useless. Even Bien-Zenker will not help you.

Very well-founded and sensible contribution Stuttgart0711. Your choice of adjectives shows how well you have dealt with the different types of construction. You surely also write Amazon reviews with comparable expertise.

@Hous: The choice of adjectives is completely irrelevant here, I have dealt with this for almost 18 months, and in detail. I am currently building a house, designed by myself and choosing the materials myself, and also largely managing the construction supervision on my own, even though there is still a "real" construction manager. My neighbor built a prefabricated house with Weiss, next to me, and that one also without a basement. Construction time from foundation slab to moving in was 8 months.

Two houses further down a prefabricated house from Beilharz is being built, next to that another prefabricated house from Okal Haus. I am on site every day and see or rather have to see what people are putting themselves through out of ignorance and fear of alleged insolvencies with solid construction methods. The main argument presented to customers at the Fellbach exhibition is primarily one, namely everything fast (house stands in three days) and everything from a single source. Many people agree to that because it is assumed that it would be much faster.

What is delivered is essentially the same, regardless of the provider. Timber frame prefabricated components, already installed windows, tongue and groove concepts, loads of insulation, plywood and above all huge amounts of gypsum board panels for interior finishing. The perceived value is tangible, visible, and also audible. One thing unites all providers equally, if someone wants to break into such a house, they just have to kick the wall in the middle, and they are inside. You don’t manage that with a 36.5 cm brick.

Attached are some pictures. What would you say is more valuable or mechanically more load-bearing, the cardboard with presswood walls and luncheon meat or 24 cm concrete walls in the basement and monolithic construction made of bricks or other stones on top, 15 cm sand-lime bricks walls and ceilings made of in-situ concrete? The houses are also nearly the same price in construction costs.

Don’t degrade me to a blabbermouth who doesn’t know what he’s talking about

There are different Philos

There are different philosophies with different solutions. In the end, the result should be evaluated (thermal insulation, soundproofing, strength) against the given requirements, which can vary greatly depending on the builder (mechanical strength of a bunker, regional, sustainable, price certainty, etc.). The time argument is currently irrelevant, which you surely know due to your 18 months of research. Safety evaluation includes both burglary and fire protection. In both cases, this does not depend on the construction method but on the materials used and their installation, which is why no generalization can be made here either (for example, Styrofoam or the choice of security class for doors and windows). The decision for or against a basement is also independent of the construction method. Last but not least, not only the construction method influences the result but many other things such as design, planning, and above all execution. No matter which electrician (electrical company or general contractor (solid or wood)) connects the cable incorrectly, it does not matter and leads to an error in both cases. Due to the above explanation, I consider your opinion to be unobjective, generalized, and absolutely unhelpful for people like the OP or others facing the same problem and seeking factual assistance.
