Masonry - individually planned single-family house construction

: correct. see my previous answers. It is currently the better price/performance offer overall. If I am sure about the construction of the wall.

After intensive work with Excel and many months of careful analysis, we have identified numerous differences.

That makes me curious: differences of what?

@ YPG: Solar system, larger garage, concrete instead of wooden ceiling. Just to name a few. But as I said. In the end, everything has to be right. The building fabric should be correct. But as far as I can understand here, you are of the opinion that the wall structure is not structurally problematic. But as with every topic, just like now through the forum, there are simply different opinions.

Statics is not an opinion, statics are calculations that are either correct or incorrect. And as a rule, it is assumed that the structural engineer calculates correctly for something rather trivial like a single-family house. Then it fits.

The wall construction is a matter of taste. Although it is beyond me how the construction with aerated concrete can be more expensive monolithically than the building method with sand-lime brick / Poroton + insulation, because the work steps alone double. Whether I use 17.5 Poroton bricks or 36.5 aerated concrete... In the end, it is a question of weight, nothing else.

@Machselbst: Thank you for the quick and clear response.

You can read in "Planänderung: Aus der Beton- soll eine Holzdecke werden" and in "Leichtbauwände in Massivhäusern?" why it is by no means a matter of lower value if you are offered a construction that is cheaper according to pub opinion.

I find it hard to understand how construction from aerated concrete can be monolithically more expensive than the construction method of sand-lime brick / Poroton + insulation, since the steps alone double. Whether I take 17.5 Poroton mason or 36.5 aerated concrete... In the end, a question of weight, nothing else.

You forget the power of the bonus scale, nothing else. The general construction laborer playing cards doesn’t cost any less than the one doing facing bricks, even in medium-sized general contractor building projects utilization and routine count more than anything else. Single-family houses are peanuts here, they shouldn't cause trouble as well. Some things simply have a price that makes you shut up and sign. But basically you’re right, I would expect at most price parity here, cheaper goes too far. But I can actually get the Jimny 2025 as a five-door cheaper than as a three-door (I still prefer the shorter one).
