Bungalow, only 2 companies, which one to choose?

Sorry, you just can’t say that in general at all. A 24 cm hollow brick + 12 cm ETICS is definitely not cheaper than a 36 cm monolithic wall structure (“cheap construction” can’t be true). A multi-layer wall structure offers higher thermal insulation with the same brick and the same total wall thickness, so it is functionally better.

I also can’t understand the arguments against ETICS anymore: if you can’t attach a mailbox there, you just have to find a craftsman who can do it. And no hole has ever come from leaning a bike against it. If a bike falls against a solid wall with force, that doesn’t go by without leaving a mark either. But this discussion has been held here a thousand times already. It’s always nice with our house: “Why are you building an Efficiency House 55 with ETICS, nobody needs that” and then at the floor plan “The air space and the rooms... everything is so open, you’ll never get it warm... just think about the heating costs”... after both arguments are made, I repeat them again and just answer: “So, do you notice something?”

Do you notice something? No one said anything against ETICS, nor has anyone questioned kfw.
We also have ETICS. Even though I still believe it is the cheapest option to implement the Energy Saving Ordinance, I haven’t said anything against it. If you stick with it, however, you have many disadvantages or higher effort if you want to maintain long-term quality, e.g. mineral plaster/algae. Or you have fewer options to attach building components to the house. Of course it’s possible, but you can’t just easily mount an awning or something like that.
And in combination with

- Interior walls simply drywall,

all extra charge

Roof overhang 30 cm extra charge

...the builder is probably one who generally offers very cheaply, but in the end charges for every screw separately.
That’s no problem if you are offered a modular system in house construction. But a lot gets lost that a healthy scope of work description already includes. I know very well what that means, because it was the same for us. What we didn’t know, we didn’t ask about and afterwards we pouted.

Sure, the big one also delivers good houses to customers, but the small one can do things the big one can’t.

That’s how it is.

What is included in the smaller company I can’t say, these things were not discussed, it was only about the whole house and our ideas at first.

Have them give you the scope of work descriptions for comparison.

For example, only 3 sockets were calculated in the kitchen, he said we should talk to the electricians and that they would then give us a separate invoice for all the extra things like more sockets, network, satellite etc.

Yes, of course. But these are also costs you will have to pay.

I just can’t really imagine it getting cheaper, they could hand you a hefty bill, either pay or tough luck, right?

Unlikely, but possible.

Likewise, he advised us to only take aluminum window sills and to have them replaced by granite during construction, or to only leave aluminum in place.
But then others told us that it is supposed to be very loud in rain/hail.

What you understand by utility room you ultimately have to decide yourselves. One says yes, the other says no.

For the tile price both were at 15€ with the bigger one, but the tile sizes were “prescribed” and also the area....

15€ isn’t much.

Mottenhausen feels offended because I called the ETICS inferior to monolithic construction. I stand by it. I know many ETICS buildings; they are owned by our administration. They are warm, yes, but the facades are sensitive and prone to algae growth. Unfortunately, it is often visually unsatisfactory due to rushed execution; the pattern of the panels shows through the plaster, and forgotten corners lead to mold inside. Therefore, I would build monolithic myself and always have. The wall is truly massive. The plaster is homogeneous, smooth, algae growth is not an issue, fastenings are easy; only the thermal insulation realistically ends at KfW 55, rather at KfW 70. But that is completely sufficient for me. We insulate and insulate like mad, stick everything airtight, can hardly breathe in the house, and then buy a controlled residential ventilation system for tens of thousands. Sick system. And most builders have a high school diploma and don’t get it. K.

Ahh the Nordic hermit with the cheap bungalow is ramping up again... You really are the biggest troll in the forum

You can feel free to ignore me. Otherwise, it should be normal to tolerate different opinions without insulting or showing arrogance. I observe. Our house was affordable, not cheap. I am neither a recluse nor a troll. And you are rude.

The monolithic wall construction is also better. Neither EPS is needed nor do you have that hollow exterior wall that breaks if you accidentally hit it with a bicycle handlebar, and to which you can hardly properly attach the mailbox.

They are warm, yes, but the facades are sensitive and are prone to algal growth.

Monolithic is of course better than the two-part exterior wall. However, it does not break because of a bicycle handlebar nor is it impossible to mount a mailbox on it. It does algae more easily, yes. You are both right and wrong. You are wrong with your examples, Motorenhausen turns your (incorrect) factual explanation into something completely different. But that does not make the ETICS better or worse. Do you have a grudge here, or what?

I'm actually not feuding. I just positioned myself a bit drastically with the mailbox and the bicycle handlebar. You know me, I'm a lamb. Completely harmless. Always peaceful, never wishing any harm to a fly, I am the personified incarnate neutral Switzerland......
