Interior walls: masonry or drywall?

Before the screed, plastering is also done, which is much easier when the wall is already finished. Just do it the way that has proven itself (so first the walls, then everything else). If you deviate from that, it will only get complicated (not necessarily impossible).

But drywall construction can be done afterwards, right?

Are the interior walls actually also built before the roof?

Do you roughly know the prices? Between masonry and drywall? From what I see, drywall is more expensive than masonry?

I like that we exchange ideas like this[emoji106]

Of course, the massive interior walls are constructed before the roof. They should preferably also be finished before pouring the concrete ceiling, even if they are not load-bearing. The integration of the interior walls into the exterior walls must also be done professionally, otherwise the wall might eventually end up on your sofa.

My feeling is that you are pursuing the wrong approach here. Your bricklayers come with ready mortar for a day’s work, with a stone saw and with experience. In the time you have been thinking about the correct execution here, the bricklayers have already built up all the interior walls.

The pipes will already be in place as they lie in the exterior walls! It basically only revolves around electricity, LAN, and TV cables for each room!

Pipes are not installed in the (solid) exterior walls!

Whether drywall or solid construction, it doesn't matter; the interior walls are always built during the shell construction before the rough-in of plumbing/electrical.

The roofers also only come in once the shell construction (including interior walls) is completed.

Special case drywall: Only one side is fully covered, on the second side only a panel is placed at the bottom (to prevent the screed from flowing away). Insulation and electrical installation are added later into the still open drywall after the screed.

Special feature drywall: Only one side is fully paneled, on the second side only a panel is installed at the bottom (to prevent the screed from running away). Later (after the screed), insulation and electrical installation will be added into the still open drywall wall.

We have OSB boards on the attic floor, on which a floor heating system is supposed to be installed and then, logically, screed will be poured.

So does it make sense to fasten the drywall wall firmly to the boards and then basically panel both sides at the bottom?
