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

Well, for example, we don’t have: mechanical ventilation with heat recovery, water heating systems, or solar panels, a fireplace, colored windows, hardwood or plank flooring, etc. – instead, we have simple 36.5cm (14.4 inches) Ytong blocks and white plastic windows.
But like many others, we have treated ourselves to certain luxuries. For instance, a high-quality staircase.

winnetou787 Aug 2017 20:07Good living space ventilation is certainly nice, but I wouldn’t call the rest simple.
A house insulated with 24 cm (9.5 inches) Ytong plus additional insulation is cheaper here than the solid version.
In the new development area, you can get a KFW 55 townhouse with land for just under 220,000, and of course, there will likely be some additional items not included in the specifications, but it’s simply that affordable here.
Elsewhere, you wouldn’t even be able to complete the house within that budget.

What are the wall and ceiling surface finishes like (plastered Q2 or Q3)?
How much tiling is there in the bathrooms? Up to what height?
I would plan a 10,000 buffer for selections. At least for things like power outlets, the standard included will most likely not be sufficient.
What bothers you about this offer, for example, that you would want to leave something out? See your initial post

Please name a provider. All the providers I contacted at the time wanted to know whether the plot is in Berlin or Brandenburg before quoting a price. None of these providers had a city villa offered anywhere near these prices. There is also no reason why the pure construction costs should differ significantly between Berlin and Brandenburg since all providers building in Berlin actually come from Brandenburg, including the really large developers...

First of all, thanks for that!
By the way, I clicked in the wrong place, I live in ST (Saxony-Anhalt).
Regarding construction costs:
I have already received several offers, including from the company Helma.
The house in question is roughly as follows:
- approx. 142 sqm (1,528 sq ft) net floor area (127 sqm (1,367 sq ft) living area)
- gable roof with a 42° pitch
- knee wall 0.875 m (2 ft 10 in)
- KfW 55 standard
- brick masonry 17.5 cm (7 inches)
- external thermal insulation composite system 160 mm (6.3 inches) with thermal conductivity class 035
- triple-glazed windows with a U-value of 0.5 W/(m²K)
- secondary entrance door
- underfloor heating / heating (NIBE exhaust air heat pump F730 with central exhaust air and decentralized supply air including domestic hot water tank 180 liters (48 gallons)) <-- I definitely want this changed!!!!
- clay roof tiles
- colored exterior plaster
- house corners clad with facing bricks (included as standard)
- cantilevered wooden staircase
- multimedia network installation
Cost = 218,000 €And then after signing the contract, there are at least 4 more occasions to spend additional money: 1) selection appointment, 2) civil engineering works, 3) electrician, and 4) tiler. [emoji1]Similar topics
