Interior walls made of drywall or masonry?

Hello everyone,

we are doing the entire interior construction in the house ourselves and are currently facing the question of whether the interior walls should be completely made of drywall or if we should rather have them built with masonry.
Drywall would of course be cheaper and more flexible. However, we have concerns regarding a possible resale.
The house will otherwise be built solidly from KS.

I would therefore be very grateful for advice and opinions.

Have a nice weekend!

For us, it will be like this. Where we might want to make changes (in the next few years), e.g. no dressing room but a larger living room, or no semi-open but an open kitchen, drywall will be used. The rest will be built with masonry.

It now reads as if the question is urgent - however, I only recently recall your question about the general topic of shell construction / shell house and therefore suspect that this is still a fundamental question in the planning phase.

Otherwise, the house will be built solidly from sand-lime brick.

I don’t believe that, I currently only know sand-lime brick with ETICS. Load-bearing walls at least are not done in drywall, and even non-load-bearing walls can be bracing and then also cannot be drywall. Is it supposed to be a house with straight-walled upper floor or with sloping attic? Basically, both have comparable labor costs, but sand-lime brick is something the self-builder won’t do for weight reasons anyway. I think your question still needs considerably more background facts.

We are at the very beginning, planning is underway (I don't have a plan yet, it's initially about various fundamental questions). It concerns a house with 2 full floors and a hipped roof. We would (have to) outsource the drywall work, the main contractor would do the masonry if we want. And yes, sorry, of course KS with ETICS.

We would (have to) outsource drywall construction, the general contractor would do the masonry if we wanted.

The insulation of warm roof/cold roof and claddings of sloping ceilings and room ceilings is carried out by a drywall specialist,
so he is already on site and can also build walls.
Or is the general contractor so big that he does not allow any deviations?

(I don't have a plan yet, for now it's about various fundamental questions). It's about a house with 2 full floors and a hipped roof.

It's not about the exact floor plan and room dimensions: the essential difference is whether the interior walls adjoin the roof slopes. I interpret your description as a "city villa," meaning the upper floor is a full straight-wall story, with the roof pitch only starting in the attic. And with a hipped roof, presumably also trusses – here again the key point is whether there should be a concrete ceiling between the upper floor and the attic.

We would (have to) contract drywall work externally, masonry would be done by the general contractor if desired by us.

I have understood whether the masonry trade or drywall trade would be involved. But have you also understood that some interior walls are load-bearing or at least bracing, and in those cases there is no choice but masonry?
I also don't consider the question suitable to be decided by laypersons: where there actually is a choice, you are not competent to professionally assess whether gypsum boards or drywall would be better suited. Moreover, I see you having the choice only for part of the walls: ideally, you will be able to decide this for about 25% of the walls on the ground floor and – assuming a wooden ceiling there – for about 50% of the walls on the upper floor. The rest is determined by static conditions, where there is no discussion possible.

For sloped roof attics, the answer would be shorter and would be: forget about wanting to build gable-parallel walls in masonry. Professionals don't do that for good reasons as long as it can be avoided.
And, as mentioned, you will probably not want to use sand-lime brick for weight reasons; instead, you will rather switch to aerated concrete (for the relevant interior walls).

Let's put it another way: Having all walls built from masonry is definitely possible, although it may be more complex due to the structural requirements. However, having all walls made of drywall will not work unless you provide some kind of supports instead. With two general contractors we negotiated with, everything made of masonry (sand-lime brick) would have been possible for a small additional cost, but then we didn’t see the added value compared to a properly executed (double-layered) drywall wall.
