Assessment of total costs for new single-family house construction

The trend is toward a second outdoor water tap for maximum flexibility when sprinkling the lawn and watering the flower beds.

Another technical device that might need maintenance, possibly. Oh, nooooo.

Unfortunately, the house has no lighting... and you'd actually like to showcase your house in the dark, just like in glossy brochures.

Of all the things—fireplace in a highly insulated new build, central vacuum system in the age of robot vacuums, light scenes because people are too dumb to operate a light switch, etc.—this is probably, in my opinion, the most pointless idea ever. No offense, but I won't build a model house, and lighting up your house just so the neighbors have something to stare at is kind of like tuning an Opel Manta.

I can agree with Payday’s opinion.
Even with priced-in optional features, there is still demand that isn’t necessarily extraordinary.
You also have to take the lived standard into account: someone who has to consider every expense might forgo controlled residential ventilation, etc., so that—for example—the biggest wish for electric blinds can be paid for, plus 1–2 extra sockets...

Electric blinds are basically standard anyway, right? They definitely bring more comfort than controlled residential ventilation, since you really spend ages cranking everything up and down (while ventilation can be nicely managed by tilt ventilation on 300 out of 360 days).

Someone building in the high-end segment already, where the number of windows doesn’t matter and LAN is installed in every room, then additionally spends money on wall outlets, KNxdabums (KNX?... no idea, just read it somewhere), bus systems, and alarm systems.

Huh? Because provider X has a few more things in their standard package, do you automatically add more extras with provider X?

As a builder, you kind of want to upgrade some things, even if few, in relation to the usual living environment and build technically state-of-the-art.

However, the standard is viewed individually. You can see that in the demand for outdoor water taps.

I already said that. And once you’ve moved in, after 6 months, the new house becomes your own standard. That’s why I would first have functional things installed (electric blinds, controlled residential ventilation, number of sockets, outdoor water taps, ceiling outlets, SAT/LAN) before thinking about aesthetic frills or high-end bathroom fittings. The standard there is certainly not bad; at least it’s a standard line from a brand manufacturer. I don’t know what kind of building service specifications you guys have floating around.

Ever heard a bit about example statements? Controlled residential ventilation and electric roller shutters are placeholders.

(el. Rollläden, Kontrollierte-Wohnraumlüftung, Anzahl Steckdosen, Außenwasserhähne, Deckenauslässe, SAT/LAN), before thinking about visual gimmicks or higher-quality bathroom fittings.

But that's exactly it: the high-priced houses already include the additional services you have in mind. And if I already spend roughly 50% more for a house than average (including el. Rollläden, Kontrollierte-Wohnraumlüftung, Anzahl Steckdosen, Außenwasserhähne, Deckenauslässe, SAT/LAN), then the visual gimmicks or the higher-quality bathroom fittings are no longer that significant.

The standard there is certainly not bad,

Who wants a "not bad" in their new house?

I don't know what’s floating around in your construction service descriptions.

At least an architectural service in the form of a successful and individual house design tailored to our needs.

Who would want a "not bad" in their new house?

99 percent of the people? To put the proportions into perspective, you get a bad house for 150,000 EUR, a good / not bad house for 200,000 EUR, and a perfect house for 2,000,000 EUR (based on the same square meter area). And being satisfied with what you have and not always striving for more and better and even more is an important character trait to be permanently happy. You always adapt to your current standard of living, that is not a theory, but scientifically proven. People with a 200,000 EUR annual income are statistically not happier than people with a 50,000 EUR annual income, even though the former can probably afford the significantly nicer bathroom and certainly do on average. Whether the tiles ended up costing 200 EUR per sqm or 30 EUR per sqm, after a few months you don’t care anymore. Guaranteed. The current environment, no matter how good or bad it is, simply becomes standard. Likewise, a new bathtub is a new bathtub. If it wasn't a functional wrong purchase (too small, too big, drain in the wrong place), then after a few months it doesn’t matter at all which brand logo is on it. Of course, that should not stop you from spending 20,000 EUR on additional equipment, it's your money / you still have to pay off the debts. But a bit more sobriety regarding housebuilding and car buying would do many good.

I don't think anyone would want to contradict you there. (Except of course your mentioned numbers and examples, but that's not the point) And if you read my post carefully, you can see the confirmation. It's simply about additional costs that will always occur. Whether small or large - always in relation to one's lived standard of living.

so the following "mandatory options" were missing in the basic equipment of our construction companies:

- outside water connection on the house for the garden
- outdoor socket including switch
- the warm edge on all windows
- more window/door fittings to achieve the commonly used security class 2 today (without safety glass)
- electrical equipment did not even come close to the minimum requirements (4 sockets per room, no LAN, only 2x TV sockets in the entire house)

oh yes, now I have read your other thread regarding your GÜ choice and then a lot becomes clear to me as well. So yes, if you build with such a GÜ, then the list of additional costs will indeed be long.

Hello, I happened to come across this thread and wanted to ask Grym which construction company he was talking about? Maybe you still read this, even though it’s been a few years...
