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

For me, the price per square meter is always for a “move-in ready” house. Excluding additional construction costs, kitchen, land, etc.If I subtract the additional construction costs from my total, I arrive at a house price of about 218,000 euros
(I count additional construction costs as earthworks, utility connections, engineering fees such as architect, surveyor, structural engineer, the blower door test, and the 50 euros for the building notification to the authority)
That would put me at 1,557 €/m² (144.7 $/ft²)
If I had left out the garage and used plaster instead of clinker brick, I would probably have ended up around 1,300–1,400 €/m² (120.8–130.1 $/ft²).

If I had left out the garage and used plaster instead of brick cladding, I would probably have ended up around €1,300–€1,400 per square meter (about $121–$130 per square foot).Seriously?! Of course, the garage is NOT part of the construction costs of the house!!! How is that so hard to understand? Everyone calculates costs for the building itself. Period. Congratulations on €1,400 per square meter (about $130 per square foot). Enjoy it...

DaGoodness9 Aug 2017 21:17However, it is unfortunately not so easy to exclude the garage from the calculation, as we did not receive an individual invoice for one garage. Instead, items such as the foundation slab, masonry, and facing bricks are included in the fixed price from the shell builder. At most, I could estimate the costs for the garage door, the two doors, the window, electrical wiring, interior plaster, and the garage roof.
Marvinius II9 Aug 2017 21:29I also arrive at 1700 €/m2 (1700 €/square meter) as the turnkey base price from our construction company for the building construction, plus painting and flooring done by ourselves.
But then there are the additional structural reinforcements, the civil engineer, the usual incidental construction costs, the landscaping, the furnishings...
So, you should not base your planning solely on this value when organizing the building project...
