New construction - How to build economically sensibly?

The TE is, as I gather from the profile, from SH. If I can build in SH in 2017 for 285k all inclusive with land, connections, earthworks, landscaping, pipapo, he can do that in SH too. He wants to build bigger, ok, but he also wants to invest 200 into the pure house, not like my 163. Don’t let yourself be misled, it’s possible. It’s possible without ending up in corrugated iron.

That is tendentious in language. Cheap always has the connotation of inferior quality. Let's say, affordable. Reasonably priced. A Ytong is not inferior, a white window is not functionally worse than a gray one. A 400 t house can have the same concrete in the foundation slab as a 200 t house. A Tegalit roof does not seal better than Harz tiles. A 25 cm tile does not shower differently than the 50 euro per sqm variant. KNX does not make the light different than a light switch. A plastic front door is not energetically worse than aluminum or wood. A fingerprint sensor is not safer than a good lock. Softwood roof undersides protected with consoles are not worse than those made of plastic panels. Etc.

Sorry, I said cheap! Not inferior!

And yes: I consider 200000 to be cheap - according to OP 130/140 sqm, without explanation one can assume turnkey (without painting and floor coverings).

We also built relatively cheaply - cheap Lower Saxony, but 3 years ago over 200000 with decent double glazing and clay roof tiles. Not necessary and would have blown the budget

After that, from an economic perspective, buying/building property is almost always a "loss" business.

That is also correct. However, many people cannot calculate this and therefore say that homeownership should serve as security for old age. Furthermore, they do not know alternative forms of investment for savings and do not acquire knowledge about these, but instead let their minds be influenced by what the mainstream thinks about it.

Nevertheless, as long as one does not argue purely financially, there are still plenty of reasons for homeownership. After all, who wants to make every life decision purely economically rational and then go to the grave rich and unfulfilled?

In the end, one must be clear about what one wants from life and for what one wants to prioritize spending money accordingly. And for those for whom individual living, loyalty to location, and freedom of decision enjoy high priority, owning property is a good choice.

I would first check how much the house including additional construction costs is allowed to cost - then you can see what you can afford.
200000 thrown into the forum room: Never ever a home for 3-4 people.

I completely agree with you.

We are at 134/125m² KFW55 turnkey per general contractor <200,000 The problem in forums is always this: Showing off is more the rule than admitting that you can also go cheap. Therefore, the average forum price is always higher than the average market price.
