ᐅ Planning: Demolish an 80 m² old building and construct a wooden house on the site

Hello dear community,

I have tried to read through the posts here and was able to understand quite a bit. Now I want to share my planning with you to possibly correct any misjudgments or mistakes on my part.

I am a 33-year-old married man with two children, currently renting in Baden-Württemberg. My parents own a plot of land in a small village in Rhineland-Palatinate. Now I am considering building a small wooden house there using a prefab wooden house manufacturer. Currently, there is an old building on the plot, parcel 37A. At first, the idea was to renovate it and make it habitable again. When I called the craftsmen, each of them said it wasn’t worth it; even the energy consultant advised against it. Since I am not a professional in this field, I took their assessments seriously and am now thinking about demolishing the old building and constructing a wooden house instead. The old building previously had a water supply and still has an electricity connection. The water supply was cut off by my father due to the risk of water damage.

The old building measures 6.50 meters (21 feet) in width and 9.50 meters (31 feet) in length.

The plan is for a prefab wooden house with a smaller footprint to simplify the building permit / planning permission process or to avoid complications with larger structures.

I am open to any criticism or questions.
I have also included a rough cost estimate.
If I have forgotten any cost items or if any cost items seem unrealistically priced, I would appreciate your experience-based feedback.

Many thanks,
Your layman

So, if you follow the link, you’ll find different figures. The building specifications, uhmm. Don’t need a roof? Heating, tiles, building permit / planning permission (which is probably included in the additional construction costs)? It’s just a pile of materials delivered to you, so it’s an entirely different type of warranty.

Payment terms: no guarantee is a no-go.

Conclusion: add a bit more money, and have a local timber builder do the job—you know exactly what you’re getting, with warranty and guarantee.

Basically, none of the important details have been mentioned:
What kind of development area is this? Is there a zoning plan? What is allowed to be built? Does Paragraph 34 of the Building Code apply?
Then all the technical aspects are missing: there is no utility room, no power supply, just the bare wooden structure. Foundations are also missing. This requires earthworks.
And who is financing it? Is there a bank that would finance such a project? How liquid are you?
Demolition and disposal also have costs.

Thanks first of all for your opinion.
1. The roof is included in the building kit. You are right, I forgot heating. I have a cost item for the bathroom which includes the tiles.
2. Yes, exactly. Material and then self-assembly, or I also have a cost item of 22,000 Euro (about 24,200 USD) for installation in my cost overview.
3. I called several customers who built a similar house with Pineca and they all made such a payment, so I believe it should not be a problem. But thanks for your opinion anyway; I will take it into account.
4. I will try to find a timber builder who can do this in my region.

Thank you for your opinion and your time.

Thank you very much for your opinion and criticism.
1. It is an old development area.
2. There is a zoning plan / development plan.
3. I am currently in the planning phase and do not yet know what I am allowed to build. I just wanted to share my planning ideas.
4. There is no utility room. The costs for the power supply are included in the cost overview and would be addressed later on.
5. When I inquired at my local bank, they said I could get financing up to 200,000.
6. Or do you mean that no bank would finance a wooden house?
7. Demolition and disposal will be done privately; I have also included these costs in the cost overview.

Thanks again for your opinion.

In short, you receive a shell package for a house to be finished by yourself. Everything else still needs to be done, from the necessary connections, wiring, and systems (electricity, water, heating, ventilation), the prior building permit / planning permission, the interior finishing (floors, walls, bathrooms), to the required construction of the foundation or slab.

In conclusion: the house will end up costing about the same as any other house. I’m not trying to speak badly of these houses. However, as a bank, we would not grant you a loan for this house, as it would rather be classified as a holiday home.
