Construction costs rise by up to 30%

2. Building with an architect on your own initiative is, according to experience, always 10-20% more expensive in the end than initially estimated by the architect.

Where do you get these figures that you are quoting here? On what experience is this assumption based?

You can always read this here in the forum. And by the way, this topic is also repeatedly discussed on various websites about construction.

For many (for God's sake not all !!!!) architects, cost control plays a subordinate role. Furthermore, the clients usually have not conducted a single sample selection by the time the cost estimate is prepared by the architect. This then simply makes it even more expensive.

Family and friends have had the same experiences with different architects.

Even credit institutions recommend factoring in a higher buffer when building with an architect.

Whether it is always 10-20 percent, I would not say that so generally, nevertheless, in our case it is pretty much exactly these alleged 20 percent additional costs.

But we do want to remain serious and linguistically precise. You read a lot on the internet! And just because some forum members report bad experiences, you can't just lump all architects together like that. And before I educate the OP here in this way, I would first consult some representative figures!

It is true that building with an architect is often somewhat more expensive than planned. However, this is not due to rising construction costs or faulty planning. In 80-90% of cases, it is due to the clients who change materials and fittings during construction. Essentially, an upgrade during the ongoing process = higher quality = more expensive.

In 80-90% of cases, it is due to the builders who switch to different materials and fittings during construction.

Then there would be no difference to a general contractor, because the average builder does the same there as well. It's actually no surprise. The general contractor calculates his offer and "backs" it with his own profit. Because if the construction becomes more expensive than contractually agreed, he has to start saving or bear it himself. The architect, on the other hand, only estimates, his profit is secure – not to say, the higher the construction costs rise, the higher his profit becomes. In this one point, the general contractor is more of a partner out of self-interest than the architect.
