Hello everyone,

we ("young family") have been searching for a house in NRW for some time. In our desired region, good existing properties are rare, sell within hours/a few days or with corresponding "under-the-table money." Therefore, the question "build a house yes/no" arises on its own after a certain "period of hardship."

On the relevant real estate portals, prefabricated house providers keep popping up at seemingly low prices. This still makes me suspicious, but at least I want to deal with the topic as an "informed customer."

I have therefore tried to piece together an example calculation – my knowledge is limited to a few hours of internet research (so it is very manageable).

Offer from the prefabricated house manufacturer Allkauf Haus for a shell construction house (without basement) in my desired region: Sales price €250,000.

Included are:


    [*]Simple shell construction house 123m² living space, 4 rooms
    [*]400m² plot
    [*]Concrete slab
    [*]Architect services and planning flat rate
    [*]Efficiency 55 standard
    [*]Blower door test
    [*]Triple glazing
    [*]Roller shutters
    [*]Solid wood staircase
    [*]Construction security package
    [*]Expansion package 1 (home technology package including piping, heating system and electrical package; insulation and paneling package; solar system for domestic hot water heating; ventilation system with heat recovery
    [*]Expansion package 2 (sanitary fixtures, tiles and window sills, interior doors including frames, floor coverings, wallpaper)


So far so good, I am aware that you do not get a habitable house for €250,000 in our region. The plot costs - estimated according to the land value - €140,000. Here is my calculation:


Plot €140,000

Property transfer tax €9,100

(?) Broker commission for plot €7,000

House €110,000

Land registry €2,100

Notary €2,100

Building permit €700

Surveying €1,000

Appraisal €3,000

(?) Development costs €16,000

Insurance €1,000

Structural engineer inspection €1,000

House upgrades €10,000

Labor costs interior finishing €50,000

Garden €20,000

Double garage €20,000

Total €393,000


I find the labor costs difficult; I want/can do little to no work myself. For form’s sake, I assume an undeveloped plot without major earthworks. Should a basement be added, I assume about €40,000 including earthworks. Whether broker commission applies to the plot (or not) with prefabricated house providers I cannot assess; property transfer tax will presumably only apply to the plot. I have assumed €10,000 more than the standard, although the basic equipment (tiles, sanitary fittings, etc.) looks okay to me, at least according to various construction blogs.

Do I have any major conceptual errors or is it roughly correct?

Many thanks in advance for your advice!

Best regards

So, I know the offers from Allkauf Haus, the additional construction costs are always added on top. The real estate transfer tax probably has to be paid for both, but no broker commission should be charged for that. Where is the construction supposed to take place? There are regional differences, which is why the construction location specification is required here in the forum.

Thank you for the quick response.

I have tried to list all incidental construction costs separately, see above (but I surely forgot something).

Construction is planned in the "Düsseldorfer Umland," meaning the suburban area, village outskirts, Neuss, Kaarst, etc.

Your reasoning is heading in the right direction. Because as you described it, your goal is a turnkey prefabricated house.

Of course, there can always be price deviations due to the plot, excavation, additional garage, garden design, etc. The Düsseldorf region, to stay with the example, is more expensive than rather rural regions in NorDeutsche Reihenhausein-Westfalen.

You are welcome to arrange a personal appointment with one of our Bien-Zenker consultants near you. They can also provide you with an offer including a specific price according to your wishes.

Why is everything so complicated? The calculation for a move-in ready house is very simple: number of sqm x 1800-2000 EUR (depending on the equipment) + additional construction costs + plot + garage, cellar, etc.

Any provider who promises you significantly lower prices is either fooling you or botching the job. This can almost be called a law already in 2017.
