Costs of different house types

Oh, I thought flat roofs were more expensive because of the more complex waterproofing? I believe I read that shed roofs are the cheapest roof type.

For this, one reads all possible answers, so honestly I doubt that there is a generally cheapest roof shape. Even though we have neither a flat nor a gable or shed roof, this roof shape was still feasible without significant extra cost. My statement, however, initially refers to the ratio of envelope area to interior volume, without considering more expensive or cheaper construction.

That leads again to a thread that, apart from the contribution increment, leads to nothing. Build the house that the development plan allows you and that you like. As a rule, some shapes fall through the grid anyway and you end up with the classic gable roof or tent roof with 1 or 2 dormers. Usually, one does not drive a Dacia just because it is cheap. Otherwise, many more would be seen on the streets.

Hi everyone,
thanks for the previous answers.

therefore the next best option is a cube. The more you deviate from it, the more exterior surface you have to create for the same volume (simplified: living space).

And besides the ratio "exterior surface/volume," with any deviation from the cube (that is, with every gable, dormer, balcony, windbreak, in short: everything that makes a house interesting) there are also efforts for execution and insulation.
And that’s the point I find hard to estimate and why I am asking here.
Is the captain’s gable or the L-shape rather an expensively purchased luxury, or do the additional costs get lost in the noise?

In the end, the differences in price aren’t as huge as one might think.

That’s an interesting and helpful statement. So I probably overestimate the extra costs of “special requests”?

I think the latter is more likely. With a typical mid six-figure amount that a single-family house costs nowadays, a difference of a thousand euros more or less just doesn't matter.

That is an interesting and helpful statement. So am I probably overestimating the additional costs of "special requests"?

I think so. Of course, every little bit adds up, but if you don’t check every box on the list of special features, the surcharge in the end probably won’t be huge. Apart from that, one can certainly accumulate quite a bit more surcharge in areas such as technology or bathroom equipment.

This is turning into a thread again that leads to nothing except incrementing the post count.

Matter of opinion.
I do find it quite helpful to know how much "extra requests" affect the price.
That no reliable, universally valid numbers come out of this, but at most qualitative statements or rules of thumb, is inherent to the matter.

People usually don’t drive a Dacia just because it is cheap. Otherwise, many more would be seen on the roads.

To stick to the analogy: The goal is not to buy the cheapest car but to understand which additional equipment items are price drivers or to better assess their cost/benefit ratio.
