Hello forum members,
I am new to the forum and will be spending the next few hours and days going through the discussions. I would like to ask for your assessment regarding the following project:
We want to build a prefabricated house in Baden-Württemberg; the plot is available and has connections.
The plan is for about 120m² (ground floor approximately 64, upper floor approximately 56) plus a basement and a single garage (plus carport). We have found “our dream house” as a timber frame construction, with costs estimated at around €132,000 for a shell ready state without the basement. Alternatively, we are also looking at prefabricated house manufacturers offering solid construction methods.
- Is our cost estimate of around €230,000 (excluding the land and interior fittings) realistic for this project, or should we budget more?
- Do you have any experience with prefabricated house manufacturers?
Thank you in advance for your tips, comments, and advice.

Hi DubaiVAE,
we are starting construction this June and building a prefabricated house with solid construction, even with a company you mentioned. We chose a house model with 109m² (1,173 sq ft) and customized it according to our preferences. The final price is 238,000, just for the house, turnkey including the basement and floor coverings plus painting work (except the basement).
Best regards
LilikHello Lilik,
that might be the house called Faszination.
How satisfied have you been so far with the construction supervision and the discussions?

Hello Lilik,
could this be the Faszination house? .Yes, that's correct.

Things are moving along quickly for us; we signed the contract on April 4 and construction will start in mid-June.
Best regards,
Lilik

We have been living in the house for almost 8 weeks, and since moving in, €3000 have just disappeared. A trim here, a screw there, a shovel, a small final invoice here, another bill there... it adds up quickly. Whoever doesn’t have extra funds ready will start facing payment reminders right from the beginning.
We had set aside around €8000 for the landscaping... well, that will have to be done more economically now, because the electricity and gas from the construction phase have to be paid. Insurances also want their first annual premium, the chimney sweep expects their fee, and so on. Speaking of lighting... that gets really expensive, or a few nice pieces of furniture—even if they’re just small items for fixing damages, it all adds up. Reading something like that really unsettles me – luckily, I play the lottery.

LilikHello Lilik,
That sounds good. Last week, we were able to visit a customer’s house of the model Faszination that is already occupied.
We really liked the size and layout, and we already have an idea of how we want our floor plan. Unfortunately, we don’t know what individual modifications would cost (e.g., changing the upstairs windows to floor-to-ceiling, rotating the entrance and placing it on the narrow side...).
Conclusion: Somehow, we are quite fascinated by the Faszination house.
Hello everyone,
We are currently building a single-family house using timber frame construction with a masonry basement. In total, it’s about 230 sqm (2,475 sq ft) spread over three floors, which would cost us roughly 345,000 euros without any DIY work—about 1,500 euros per sqm (140 per sq ft). Fortunately, we had an excellent architect who thoroughly outlined (and hopefully overestimated) all additional costs in advance. Essentially, these were (of course, every situation is different!):
1. Earthworks with sufficient gravel and drainage... = 20,000 euros
2. Outdoor landscaping = 15,000 euros
3. Garage = 10,000 euros
4. Construction power and water = 2,000 euros
5. Connection work (water, electricity, telecom) = 3,000 euros
6. Notary fees = 1,200 euros
7. Permit process (building permit / planning permission) = 1,000 euros
8. Possibly structural engineer, surveyor, geomatics = 2,000 euros
9. Buffer for these items = 5,000 euros
Regarding the earthworks: We had natural soil and excellent topsoil! It couldn’t have been better—no rocks or similar issues. But there was a small water vein and a bit more gravel needed, which added several thousand euros...
Then there are all the extra requests like additional sockets, lighting outlets, window frames in a different color, stairs in a different wood type, taller doors, alternative sanitary installations, and so on. I would have all of that documented in writing upfront (e.g., extra cost per socket, etc.). I would also check out the subcontractors, ask to see the materials, and negotiate any surcharges with them. Often, the base prices are pushed quite low, and the real profit comes from special requests, including from the subcontractors’ side—especially if there was no clear offer given beforehand. So it’s very important to be clear about additional construction-related costs and special requests!
