Hello @all!
I am planning to build a semi-detached house in the Ruhr area. After reading several discussions here about costs, many of which were very informative, I wanted to ask if you could provide a cost estimate for our small home...
As a layperson, it is quite difficult to realistically assess the price quotes.
Basic details:
Semi-detached house with 2 full floors
Hipped roof (not converted into living space)
7.6m x 10.7m external dimensions
Brick-faced facade
KfW 70 standard or better
Basement (watertight shell)
What costs (turnkey) are realistic?
How much extra does the basement typically add?
I can estimate the additional costs (land, purchase, temporary power supply, landscaping, garden, etc.) fairly well—please only estimate the costs for the house itself. Thanks ;-)
Best regards
Micha ;-)

Correct, underfloor heating should be considered a standard feature. It is more energy-efficient, provides comfortable heat distribution, and saves space by eliminating the need for radiators. A heating system that remains invisible.
Regarding the Stiebel Eltron LWZ 430 Sol or other compact heat pumps with integrated compressors, potential noise emissions and structure-borne noise transmission need to be taken into account. Manufacturers provide relevant guidelines on this. Installation next to, above, or below living and sleeping areas may not be feasible. Installation instructions should be reviewed in advance. Additionally, the possibility of assembly and transport (clearance dimensions of the transport units) within the building must be verified with both the system installer and the manufacturer before construction starts, using the floor plans and cross-sections.

Bauexperte8 Oct 2011 11:26Hello Micha,
That will only be possible if your new semi-detached house is built with the basement adequately protruding above ground level. These systems require 3 to 3.5 meters (10 to 11.5 feet) of space between the supply and exhaust air; it’s difficult if the basement is completely buried during backfilling 😉
Kind regards

I haven’t gone through the installation manuals yet, but looking at the dimensions of, for example, the StibelEltron LWZ403SOL, I would still have to install it in the basement during construction ...

Yes, that’s exactly the point I meant 🙂
Installing the supply and exhaust air ducts in the basement will be a problem.
Also, I need to double-check the required ceiling height – our basement is currently planned with 2.25 meters (7 ft 5 in) without screed, so the clear height would be around 2.13 meters (7 ft).
But the question of which heating system to choose will probably keep me busy for quite a while *g*

An alternative is an air-to-water heat pump with an outdoor compressor unit and an indoor heat exchanger. The indoor unit can be installed similarly to a gas boiler, operates very quietly, and does not have issues with structure-borne noise transmission.
Although we use a THZ 303 Sol (technically identical to the Stiebel Eltron LWZ 303 Sol) ourselves, I personally prefer an air-to-water heat pump with separate outdoor and indoor units combined with a separate central ventilation system with heat recovery. This way, the ventilation module does not necessarily need to be installed in the utility room but can be positioned at the optimal location within the house. Separating the ventilation and heat pump systems also allows selecting the best combination of components, which can often be more cost-effective.

Micha&Dany8 Oct 2011 15:34Hello Thomas,
We will definitely install ventilation for various reasons. At the moment, I also prefer the solution of separating ventilation and heating. However, as I said, I will first get a proposal/offer from a heating specialist I trust—let’s see what he suggests.
Best regards,
Micha
