Semi-detached house - Which one is the best? Who has experience with that?

I did ask you how much you want to spend. Not what you DO NOT WANT TO SPEND.

I could have also considered a loan for €800k, but I didn’t want to!

So:
House, how big?
With a basement?
Garage?
At least which KfW standard?
Which standard for the house construction?
Land €180k

The rest you can figure out.

Exactly such long detours I want to avoid

Well, plots about €200k (including property transfer tax) I have read out. Then a house for €300k on it, because €600k would be possible, but should not... so I calculate with €500k.

Of course, a concrete answer to the set limit would be better.



What does that mean? Please not so vague...

To my knowledge, it is not possible in existing buildings with reasonable effort to achieve a decent energy consumption ...

If I knew all that afterwards, I wouldn’t be here with this topic

To my knowledge, it is not possible in existing buildings to achieve reasonable energy consumption with sensible effort ...

Nonsense. Who says that and how do you define effort? Is the alternative "new build" less effortful?

Or DOES the house HAVE to be kfw40 up to passive? Why does the energy throughput have to be so low at all?

Passivhaus is not necessarily that much more expensive than KFW 55, at least if you have a provider for whom the Passivhaus is not the exotic, but the energy saving ordinance minimum standard house.

To my knowledge, it is not possible to achieve a reasonable energy consumption in existing buildings with reasonable effort...

Firstly, this is (more or less) easily possible and secondly, buying a used property consumes much less energy than a new build. If you are eco-friendly and want to think about the environment, you must never build new. You cannot save as much energy as you waste during construction and as you destroy the environment. But it's still nice to live in a new house...

I am happy to be proven wrong! If the result of a renovation can keep up with that of a new build ... why not!

Low energy consumption means (to me) the energy does not have to be generated in the first place?!

And here I am looking for the interface ... maybe give up the last 5% of sustainability and keep it within limits ...

No; it doesn’t work like that. Either you are ideologically committed to it, then you go all in with the full program.

Especially if it is supposed to be sustainable. And meets your own standards in terms of building biology. But anyone planning something like that can hardly make compromises.

Or you look at how much house you can get for your budget; realize it’s not that much; cut one or the other goodie (in the sense of expensive; meaning the house will be more square; is it really necessary, etc.

Sometimes for the green conscience it goes toward more insulation, thicker walls or a photovoltaic system; but that is close to the limit of greenwashing. How the pipes, the mortar etc. came about is then more than secondary.

And 600K; with 200K for the plot is also not really extravagant; just good standard.
