ᐅ Mixing red and white bricks?

I wasn’t aware that I could post complete projects here.

That is actually the ideal format; a few years ago, that’s exactly how I documented my build here—as a kind of build diary. Back then, there were plenty of construction projects fully documented here with detailed photos, ranging from standard single-family homes to very unique houses. I miss that, and unfortunately, now I mostly see fragmented posts or sudden stops in communication.

There is a specific questionnaire here that you should fill out, along with providing floor plans, elevations, site plans, etc., to explain your project as comprehensively as possible.

In my opinion, you can only benefit from this approach by gaining insights and opinions from people who have experienced similar builds one or more times and have no financial or other connections to you.

There is nothing wrong with ketchup and mayonnaise on fries, but when you add the hot dog sauce, which provides the sweet and sour flavor, along with mustard and remoulade— which is, of course, essential on the fish burger—then it seems whoever made the snack bar menu got overwhelmed by the extra sauces.

If all of this is nonsense, what would you consider a sensible combination?

External wall: Poroton
Load-bearing internal wall?
Non-load-bearing internal wall?

If we were in a wishful thinking scenario, I would prefer sand-lime brick inside, even for the non-load-bearing walls. The upper floor could also use a metal stud construction method, but only with Q4-level finishing.
I am still looking for any advantage of gypsum boards.

However, we are not in a wishful thinking situation because everything costs money. On the ground floor, all interior walls are made of red Wieneberger brick, and I’m very satisfied.

Nevertheless, I have different priorities when building a house. Whether the brick is red or white—the desired energy efficiency should be achieved with it. Soundproofing is not a priority because much noise passes through the windows, and the walls need to be able to hold art and furniture.
It doesn’t matter to me whether drilling produces red or white dust, or which type of anchor I have to use.

Therefore, I don’t choose a general contractor based on the brick type but focus on other aspects and then hope that the contractor selects the best materials according to their or preferably the architect’s expertise, within my budget, and I trust them. The design, structural engineering, and location also influence the choice of materials. I professionally work in a completely different field than house construction.

All our interior walls—whether load-bearing or not—are made of red Wienerberger brick. The exterior walls are, of course, thicker. I don’t see any reason to mix materials, and I would only use gypsum walls where I already know that I might want to knock something down in the future...

What is so unclear about the question? Mixing red and white bricks? Or is it better not to?

Counter question: what is unclear about my follow-up question? — or why is it so difficult to use the forum search with the keyword "11ant Steinemantra" (or find it via my signature > legal notice of the Insta account "Bauen jetzt" and read it there)?
Normally, you don’t mix, and certainly don’t add any magic or test-winning bricks from baker’s flour or pharmacy magazines. Or mix exactly as an independent consultant (e.g., architect—but only including service phase 5) recommends.

I’ve repeated that as often as a cracked record:
if I’m involved in planning,
my advisees are told individually for each wall which solution is best;
if clients go to a general contractor with a building permit/planning permission design,
the wall buildup is chosen based on the one with which the contractor has the most or second-most experience in installation (i.e., used in 40% or more of their projects).

Non-load-bearing interior wall?

Exterior wall: if using porous bricks, then the insulated version; load-bearing or bracing interior walls follow the same principle as the exterior wall mentioned above; non-load-bearing interior walls on the ground floor are also the same as the exterior wall, and on the upper floors due to structural reasons and in the attic due to connections with drywall (metal profiles with gypsum board).
No experiments: as a client (layperson), don’t try to outsmart the contractor (professional) about how things should be done.
This regularly leads to disruptions in the system of wall unit, mortar, plaster, and installation expertise.

We were talking about gypsum-based wall panels (boards or large-format blocks)—not lightweight (rear) walls clad with gypsum board.
When can we finally expect the project thread to start, beginning with the completed questionnaire https://www.hausbau-forum.de/threads/grundriss-planung-unbedingt-vor-beitrag-erstellung-lesen.11714/ and the site plan as well as the design drawings? (Are you building a house or just a popcorn thread?)

If you want or need better sound insulation, then it should be for all walls including windows. Why only for the load-bearing walls?
