Hello,
I want to start building this year. However, I can’t find any website that compares the costs of different types of structural work. But isn’t this actually a fundamental aspect?
Of course, I am aware that certain construction methods lead to higher follow-up costs (such as greater insulation effort, more work for the electrician, etc.) than others. Therefore, a general statement is probably hardly possible.
Nevertheless, I am considering having a solid prefabricated house built (walls made of Liapor, cast in place). The question now is simply: how much more expensive or cheaper is this method compared to conventional masonry construction with Liapor, brick, or Ytong block? How does it compare to a prefabricated house? Which is more cost-effective?
Perhaps someone knows of a website that compares these construction methods. Unfortunately, I haven’t found one yet.
Thanks in advance for your help.

...so building companies/prefabricated house manufacturers or "all-in-one" solutions are always the most expensive?

6Richtige27 Feb 2011 15:05...so is it always the most expensive option to go with a house construction company/prefabricated house companies or "everything from a single source"? That always depends on what you expect. For example, I drive a car made in Swabia, while someone else might prefer a Romanian version of a vehicle. In the event of a crash, I might have dislocated my shoulder, while the other person, sitting next to St. Peter playing the harp, might think: I should have invested a few more dollars.
As a construction expert and I know very well that not everyone who wants to build a house can afford our (consulting) quality; that is why we voluntarily advise forum members in our free time who repeatedly ask the same questions such as:
Who has experience with...?
How can I save as cheaply as possible... DIY work... affordable options, etc.
We would much rather answer questions like:
How can I ensure the best quality for my money when building a house? This question has so far not been asked by anyone.

I don’t understand the consulting part. Everyone has a clear idea of what they want the house to look like. Now they want a price for that. A price with good/poor insulation, gas heating/geothermal, etc. Then they get a few quotes and weigh how much the “luxury” is worth to them or what they can afford. Then they look for the cheapest providers to carry out exactly the planned project.
Am I missing something? What sets your consulting apart? How do you differentiate yourself from an architect’s consulting? Did you also study formally?

Does your architect give you a fixed price?
Where does the architect source the walls—locally from a carpenter?
If the construction costs exceed the architect’s estimate by 30%, what do you do then?
The misconception is this: I calculate the cost of the house once you have moved in, but you want to know the cost when you sign the contract. These two prices often differ significantly, and you realize this after signing.
First, I check the wishes and budget, which in 99% of cases do not match. Then the client has to make compromises. There are only three options: house, plot, budget. If the client is not resistant to advice and there is a chance to build the house, we prepare an offer based on the specification of works. Then the client selects the finishes with all regional tradespeople. After that, our offer is detailed in every individual position and supported by the corresponding subcontractor quotes, resulting in a document of about 50 pages. We pass on the tradespeople’s prices to the client without markup; we only apply a 2% discount as our fee, provided the client pays invoices promptly. If the prospective client is surprisingly satisfied up to this point, we hand over the contract documents with the request to have them reviewed by a lawyer of their choice. If, by some unlikely chance, they still want to build with us, we sign the contract and start work.
This approach matches that of other prefabricated house providers, doesn’t it?

First, I check wishes and budget, which 99% of the time do not match. Then the client must make compromises; there are only three options: house, land, budget. If the client is not resistant to advice and there is a chance to build the house, we make an offer based on the scope of work. Then the client selects materials and finishes with all local craftsmen. Afterwards, our offer is supported by the corresponding quotes from the craftsmen for each individual item—about 50 pages in total. The craftsmen’s prices are passed on to the client without markup; we only take a 2% discount for ourselves if the client pays invoices promptly. If, unexpectedly, the interested buyer is satisfied at this point, we hand over our contract documents with the request that they be reviewed by a lawyer of their choice. If there is still the unlikely possibility that they want to build with us, we sign the contract and get started.
This approach naturally aligns with that of other prefab home providers, right?The architect gives me the same “fixed price” as a home builder.
Where do you buy your walls? Honestly, sometimes I feel like I’m missing something here. Where the architect buys the walls? Sorry, I don’t understand that. The walls are built by masons, and the mason provides a quote.
Why should construction costs continuously exceed estimates, especially by 30%? Professionals know what they are talking about, especially an architect. Please explain—I can’t comprehend this. Doesn’t he know how much the bricks cost that are stacked? What about plumbing, electrical work, floor coverings, and so on?
I’m not an expert, but I can’t see what’s so complicated about this. You have a floor plan, you know the exact dimensions, you know the number of doors and windows, what kind of roof, what kind of heating, what kind of insulation and quality, electrical installation, plumbing, two toilets, a bathtub, tiles, floor coverings—you can choose all of these precisely, including the type of screed underneath. You know all this exactly and can calculate it. So where’s the catch that causes costs to increase by a third?
So you pass the craftsmen’s prices 1:1 to the client and only live off 2% discount, charging no markup?
