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 am also doing the flooring and painting myself.

It's unfortunately not that easy to exclude the garage cost because we did not receive an individual invoice for one garage. Instead, items like the foundation slab, masonry, and facing bricks are included in the fixed price from the shell builder. I could at most estimate the cost of the garage door, the two doors, the window, electrical wiring, interior plaster, and garage roof.You can deduct between 6000 and 8000 euros, possibly 7000 as an average.Marvinius II9 Aug 2017 21:39Marvinius II schrieb:

DaGoodness9 Aug 2017 21:45Of course, you shouldn’t rely solely on this figure... that’s why we told our architect right from the start that we wanted a realistic calculation including all additional construction costs. We didn’t really have a detailed itemization. The plot costs were already known, and for the kitchen and landscaping we set fixed budgets, which we then stuck to.
That said, I have to mention that some of the costs often cited here as “standard” are actually significantly higher than what we spent.
A few examples of our expenses:
Excavation work: €4,682.26
Utility connections (electricity, water, telecommunications): €3,044.65
Engineering fees (architect, structural engineer, surveyor): €16,984.50
Painting and flooring done by ourselves (materials only): approximately €4,500–5,000

So I would now estimate about 18,000 euros for the complete garage.
EDIT: Although, theoretically, you shouldn’t include the facing bricks, since the brick area on the garage would likely have been used for the part of the house where the garage currently stands anyway :P

Painting work + floor coverings done by oneself (materials only): approx. €4,500–5,000Here (and with other breakdowns + plumbing) the real differences lie, not in supposed huge regional variations. I have spent more than this amount for just the above item per room without feeling like I was in the luxury segment. It simply comes down to differing standards. While some people wouldn’t even accept certain things in a rental apartment, for others these are part of their dream home.
