Cost estimation Bauhaus style

Yes, exactly, that's why I'm here. One is looking for answers, and now comes an admission to the critics.

The 2000€ per sqm is the net figure: so the estimated value is probably 2380€! This also includes 18% (architect, statics, energy) and we have already been promised 10%, but it is not yet finally discussed, all services 1-9 are also included! But maybe we don't need all of them, probably will get a flat rate! At 10% that would be 2198€. Soon costs will be discussed. I am curious.

I am learning: always ask about net/gross difference.

For us, this does not mean quitting yet.
With simple equipment one could reach 2000 gross, but now a good standard has been determined. I will find out what that means.

If an architect makes this plan, then if he works seriously, he must not only give realistic estimates, but must not forget important things, like construction power, etc.

Do you need the architect for site supervision or can an experienced master craftsman do that?
We are considering not booking 7-9. Now critics can write again.

I have commissioned our architect only for service phases 1-5 and hourly site supervision. He then invoices us €62 net. I also only let him come when needed. There will surely be resistance again... there is endless potential for savings... for example, our architect included an item in the cost estimate: clearing the plot with costs amounting to €2134 net. But during the development, I approached the foreman and asked if a digger driver could quickly go over it... the nice gentleman was rewarded with a crate of beer and my plot is clean you just have to think about some things, but don’t save in the wrong places

Clarify with your father whether he can take it over. For now, the master craftsman is only confident in his own field. Your father already has more house-building experience and will presumably have broader knowledge.

Actually, the architect should state gross.

Good standard is a flexible term. There is always potential for savings.

If an architect draws up this plan, then if he works seriously, he must not only give realistic estimates but also must not forget important things like construction power, etc.

Who says that? Just because he is an expert doesn’t mean he can’t make mistakes. You are in such an early phase that he can easily miscalculate by about 15% at this point. It is actually defined somewhere. Just Google it. You will only reduce this inaccuracy to 5-0% when you have all the offers and don’t change anything.

To my predecessor: Of course, there are price differences between SH and BY in the construction costs of a house and possibly also in the equity prices of materials, which in turn are due to higher wages. However, that’s all there is to it.

Basically, you get what you pay for. Just because someone offers you a house for €1700 per sqm doesn’t mean that the materials used are equal in terms of quality. And yes, satisfied craftsmen who are paid fairly also deliver a reasonable quality and don’t just slap something together. So a house is not just a house.

My neighbor is also building with a waterproof basement and bricks, and I can tell you as a builder that the delivered execution and quality of the materials is really bad.

Starting from the foundation of the slab, through plastered reveal edges in the basement, the proper installation of windows to insulated roller shutter boxes, an insulated ceiling gable, etc., and so on.
Just because your offer states triple-glazed windows doesn’t mean you get high-quality window profiles.

Here again, quality has to be paid for. You get what you pay for, quite simply.

So much for the estimate





It's no use estimating too cheaply.
Take a look around here.
There is another thread that dealt with the cause of additional financing or the thread why building a house always gets more expensive.

The more precisely you communicate your wishes/needs, the more accurately an estimate can be made or the first offers are eliminated

2000€ net would be a good standard, 2000€ gross a basic one. In interior construction, this standard would be reflected.

What do you think is meant by this?
