ᐅ New Construction – How to Build Cost-Effectively?

Hello everyone,

During the planning phase of building a house, you inevitably come across forums about home construction and topics related to energy standards. I have already read several books and browsed various websites on the subject. I should mention that I am not a professional in this field. What I have noticed is that the entire topic of "economic / ecological home construction" is heavily influenced by commercial interests. The so-called "smart" consumer is often misled by marketing terms and a government-led campaign for "CO2-efficient building." Books or websites dealing with this subject often do not provide clear, comprehensive assessments.

In the "better" literature, insulation materials are compared in terms of insulation value and whether they are expensive or affordable. However, I still cannot determine what makes the most sense for my individual case. I simply do not want to spend excessive amounts of money, especially on things that do not add value, such as polystyrene insulation. If additional costs for a particular heating system are reasonable over a feasible period, then yes.

Our current goal is to build a simple single-family home with about 130 - 140 sqm (1400 - 1500 sq ft). The house should cost around €200,000 (without outdoor landscaping, floor coverings, land, or additional construction-related costs; our expectations are modest).

I am interested in knowing, based on the current state of technology, what is the most energy-efficient and cost-effective building option?

Energy-saving regulation / building standards according to KfW, yes or no, and if yes, which level?
Solid construction or prefabricated house?
Condensing boiler technology or heat pump?

Thank you very much for your answers!
Best regards

I think a Q2 plaster finish, level 3, can practically only be achieved by applying filler.
If you replace the Nibe with a gas boiler, Helma should lower the price. A 180-liter (47.5-gallon) storage tank seems large to me. How many heavy hot water users live in the house? My wife and I easily manage with half that capacity.
Keep in mind, the gas connection will cost around 1,500, Karsten.

You do realize that this house does not exist, right?

I’m tired of hearing the argument: "we don’t want luxury, just standard and very simple." Maybe someone should start a thread that organizes and lists what counts as standard / upscale / luxury, along with the corresponding average price per m² (square foot). That way, people can see what options exist within standard and what they cost.
Okay, that might be difficult.

Similar listings with comparable prices can be found on Immoscout in almost every region of Germany. This is purely a bait offer for a fictional house on a fictional plot of land. It has absolutely nothing to do with reality.

It's simple, this is an advertisement. Just like with prefab home providers. "Designed" is the keyword.

And in the ad, it’s clearly visible that they just include every floor plan they have (including other house types).
