Bavaria: 2 single-family houses or a duplex?

That is not a good idea. Then you spend many evenings ticking boxes in your Excel spreadsheet and still end up no wiser about whether apples or pears are better. Price comparisons only make sense if you compare comparable things. I speak from experience, and next time I would schedule appointments with sales representatives at the next model home park much later in the process. If at all. In my opinion, Hanse Haus cannot be compared to Danwood; that's a different class. Getting a feeling is nice, but make sure you compare budget brands with budget brands or premium brands with premium brands.

I always read that you cannot compare, for example, Danwood with Hanse Haus. But why not? Both build me a house, and if Danwood builds me a house according to my wishes, why not? I also combine Lidl and Rewe in my fridge. Or more objectively asked: What disadvantages do I bring into the house with Danwood?

Is the OP the guardian of his brother? *JK* Here are two reading tips (the second is more interesting, linked in the first):

Although I am the only one writing here, we are of course discussing the findings together :)

I always read that, for example, Danwood cannot be compared to Hanse. But why not? Both build a house for me, and if Danwood builds a house according to my ideas, why not? I also combine Lidl and Rewe in my fridge. Or to put it more factually: What disadvantages do I bring into the house with Danwood?

I do not know Hanse Haus in detail, but if they are comparable to Rensch-Haus, Weberhaus, etc., then Danwood is less flexible in some areas ("eco" insulation, smart home, entrance doors, partial bathroom fittings & staircase design) or does not offer higher-priced solutions & brands at all. However, this is currently changing, e.g., one can now upgrade to wood-aluminum windows (which was not possible a few years ago), they introduced the "S-Line" equipment (corner windows used to be no-gos at Danwood), and even the Next & Vision "high-end" houses – obviously, they want to move away from the "cheap provider" image in the long run.

Also, at Danwood, some tasks are more "delegated" to the builder (road closures, construction power & water, waste disposal) – which can be seen as an advantage (saving money by organizing yourself) or a disadvantage (time-consuming, sometimes also involving liability issues).

Apart from that, the other equipment (and execution/quality) is largely identical. Provided that Danwood is cheaper after cost comparison (including everything that may be included in the base price in Hamburg and not at Danwood & vice versa), in my opinion, there is nothing against it.

According to my current understanding, I proceed sensibly as follows:

ad 1) yes, I consider them specialized and possibly even fixed, like the "prefabricated house expert" themselves. Whether they are only their cooperation partners or even a spin-off, I have not quite figured that out yet. ad 2) in principle yes. "Conversations" per se rather less. You send your inquiry (see "setting the course") and let the responses speak for themselves. As far as the participants’ offers to talk are more advisory than sales-motivated, I would see that as a plus – but in this phase I would not yet ask about it proactively. But we would have to discuss that on a case-by-case basis. ad 3) Architect commission normally to the same architect, yes. Except for example if the reflection of the "chemistry" during the resting phase of the dough has shown that one is uncertain about that. Or the architect – who otherwise can be perfectly good for module A – has already shown a strong preference for wood or stone, and you would now prefer the other. Architect commission for only service phase 3: only if the decision for wood and a certain general contractor has already been made, otherwise rather for the entire module B. I do not consider a general contractor as a contractor wrong – but all the more inadvisable is the idea to "kiss" them without a tender. The orientation inquiry round with the preliminary draft serves to select the dance partner or fiancé, but not yet the groom. A tender is an essential instrument of quality and cost control, but it can only take place after service phase 5, which provides an indispensable basis for it. Its process may have to be organized deviating from the "usual routine," whereby it is especially important that the architect already has cooperation experience in this constellation. The decision "wood or stone" (and for both: "craft-related or industrial") is best derived from the result of the "setting the course," because you do not want to carry out module B on two tracks. Construction differs significantly between stone and wood, which is why a house built in the other manner than planned is usually noticeably more expensive. With a planner of the "other confession" considerable tectonic clashes are practically preprogrammed, and "ecumenical" architects are rather a minority. ad 4) building with a wood frame panel builder, it should be six of one and half a dozen of the other whether you take Mr. Beuler or Mr. Zink. For stone we would have to take another look, I personally do not do "construction inspections." Basically, my mnemonic "3+5=8" already says that the planner and detail planner are also the best conductor of the performance.

I keep reading that one cannot compare, for example, with Hanse. But why not? Both are building me a house, and if Danwood builds me a house according to my ideas, why not? I also combine Lidl and Rewe in my refrigerator :) Or more objectively asked: What disadvantages do I get with Danwood in the house?

I find "disadvantage" too harsh a word for putting a Seat Leon (Exeo) in the garage instead of an Audi A3 (A4). After all, a generic is not a placebo.

Oh, we have already had couples here; things really got lively when the co-reader started writing themselves.

I always read that you can't compare Danwood with Hanse, for example. But why not? Both build a house for me, and if Danwood builds a house according to my ideas, why not?

The big danger with such uneven comparisons is that you overlook something, and later it costs you as much extra as choosing the other provider who has it as standard. Most people still think about the budget for tiles or that different heating providers correspond to different price categories. But if you browse here in the Danwood area, quite different things come to light. That the Polish electricians apparently don’t have a German license, and as the builder, you have to find someone who approves a foreign electrical system. The neighbor built with Danwood; they plastered in quite fresh weather this spring. Paint and plaster mixed in one bucket and just applied once, then they were done. Other providers do the top plaster and then paint twice on top. That also costs time and money.

And then there’s the matter of wall constructions. The cheap providers mainly have Styrofoam on the walls. Not everything has to be super-ecological, but that wouldn’t be for me at all. To stay with your fridge analogy, you don’t compare eggs from the discount store with eggs from a small organic farm and then say the discount eggs are cheaper, so they’re better. The result is already decided beforehand.

Well, if you click around [Hanse Haus] and "Bautechnik," you can see under wall construction the nice dark gray Neopor, just like with Danwood as well. Whether other materials can be used at Hamburg as a [WDVS-Alternative], I don't know, but what also stands out is that for Hamburg you have to fill out contact forms for all details regarding the construction service description, while at Danwood everything is linked publicly directly. For whatever reason...

Electrician is absolutely right and can also become annoying, although the Danwood sales teams can always recommend suitable companies (or sometimes directly commission them), so here you don't necessarily have to take action yourself.
