Hello everyone, I’m new here 🙂,

We are currently in the process of demolishing an old prefabricated house on a plot we purchased, down to the basement, and plan to build a new house on top of that basement.

We are very interested in a Ytong kit house, but unfortunately, we have no clear idea about the price range. Therefore, we would really appreciate it if someone knowledgeable could roughly assess it.

The construction is planned to take place in southern Baden-Württemberg.

Here is the offer we received:
House dimensions 10 x 9m (33 x 29.5 ft) + extension 5.5 x 4m (18 x 13 ft) (living area estimated at 150m² (1,615 ft²))
Gable roof 38°
Knee wall 1m (3.3 ft) with 2 dormers over 2/3 of the length
KfW 55 standard

--> Concrete slab for the conservatory extension
--> Stainless steel chimney
--> Exterior walls of the living floor + ceiling
--> Roof structure including covering, insulation, and drainage
--> Attic ladder + stairs from ground floor to upper floor
--> PVC windows + roller shutters (€34,500)

Total price €139,000 (of course, almost everything is planned as self-construction, except for complex steps such as roof structure, ceilings, concrete slab... with some assistance)

Can anyone estimate whether this is cheap or expensive?
Would it be possible to get a shell construction (structure only) without self-construction for this price?

If you have any questions, feel free to ask 🙂

Thanks a lot in advance.

Best regards

Definitely not.
(If by shell construction you mean the building envelope fully closed.)
Roughly: 100,000 € for masonry work plus your 34,500 € for windows. Then you still need the roof, chimney, and so on.

Get several quotes for comparison.
It is not cheap.

Hello Osnabrücker,

thank you for your reply. So, as you described, I could save about €40,000 (around $43,000) by doing the roof structure and chimney myself? Wouldn't that roughly be correct? In your opinion, what would be a reasonable price for the building kit?

Basically, my concern was that I don’t want to buy a kit and later realize, hmm... for that price I could have just had it built.

There is far too little information for any details.

Crane, scaffolding, and so on are all minor items individually, but they quickly add up overall.

Given the current market situation, you can only be confident with actual quotes regarding what you might save anyway.

And even then, it can still be wrong... How much free time do you have for, for example, €40,000 (about $43,000) of personal labor? You have to insure your helpers. Personal labor also means risks (both health and financial). The construction takes longer, resulting in extended rent payments, possible standby interest, and so on.

This is all just a brief overview. Take your time to inquire further, get various quotes, and then choose the option that fits you best, considering the compromises between financial, construction-related, and personal factors.

Why don’t you start the story more practically from the beginning and first tell us more about the plot, zoning regulations (building permit / planning permission), and the existing basement?

The idea of building the walls yourself is one thing – and is often greatly overestimated in terms of cost savings – but especially when it comes to a kit house, you are completely mistaken: the keywords “existing basement” and “kit” contradict each other. Kits are available for standard models, but an existing house inevitably requires a custom design.

If I remember correctly, Ytong houses are planned individually, but I still imagine that, as an apprentice mason in the first year, one should probably avoid the increased difficulty of "building on an existing basement." Apart from that, the time required is considerable, which you also need to be able to afford.
