Hello everyone,
maybe this thread is a bit early since we don’t have a planned floor plan yet. But we would still appreciate your advice. First of all, because this is probably the most important information: We are planning with a budget of 600,000 euros for the house plus additional building-related costs. We have received approval to purchase the plot shown here. We will sign the purchase contract at the end of next week. Now to our problem:
We are very uncertain about which is the better decision for our plot: a (partial) basement with a smaller floor plan (about 130 – 140 m² (1400 – 1500 sq ft)) (Option A), or a slab foundation with a slightly larger floor plan (about 170 m² (1800 sq ft)) (Option B).
I will list the pros and cons as we see them for each option.
Option A:
+ Utility room in the basement frees up space on the ground floor; no noise issues
+ More usable space overall
+ Hobby room can also be used flexibly for gatherings
+ Storage space!
+ Possibility of a double parking space
- Expensive (a full basement is probably unrealistic with our budget; is a partial basement more sensible?)
- Less space on the ground and upper floors
Option B:
+ More living space on the ground and upper floors
+ High potential for cost savings!
+ Possible to use the attic for storage?
- Is there still enough space for a double parking space?
- Possible issues with the plot ratio? If we understand correctly, the footprint of the house may be limited to 143 m² (1540 sq ft) plus 70 m² (750 sq ft) for driveway, garage, etc. My feeling is that the developed area might easily be underestimated and reach the limit quickly.
We would be interested in your opinion on how you would build on this plot. I have made a very rough sketch of how we imagine the orientation of the house and placement of parking spaces, etc. I have also attached the site plan and development plan. The questionnaire is mostly filled out, but a “final” floor plan is still missing, as mentioned. This will also largely depend on the question of whether to have a basement or not.
I hope I haven’t forgotten anything...
Best regards

A quick question for the experts, maybe this can be applied here as well.
There are online map resources that seem to have been consulted here. Some of them also have measuring tools—can you rely on those, or are they too inaccurate? I use the Bayernviewer, and at least regarding the external dimensions of plots, it is quite precise, but does that also apply to height measurement?
Personally, I would always build with a basement. It doesn’t necessarily have to be a fully finished living basement.

If I interpret this correctly, the plot is flat.I would agree with that. However, this would also mean that the plot does not require a basement “just to avoid L-block walls.”SandyBlack schrieb:
As soon as the soil report is available, we will definitely get quotes from a basement builder.The soil report is only relevant for the basement quote and only somewhat useful for deciding whether or not to have a basement.SandyBlack schrieb:
We were also advised not to get the basement through the prefab house company.Where on earth did you read that clever advice? That sounds almost like a comment from ZDF WiSo level (?). Of course, you don’t want to create opportunities for shifting responsibility at the critical interface of the top edge of the foundation (OKKD). The potential harm from this own goal is highly overrated. No, the basement builder should always be a qualified subcontractor of the house supplier.familie_s schrieb:

Since height measurements for domestic use are only about differences in elevation, the data should be sufficient to estimate driveway slopes or terrace embankments. After all, the landscaping contractor does not work with a 1200 dpi 3D printer ;-)https://www.instagram.com/11antgmxde/

blubbernase7 Feb 2022 17:25Partial basement – don’t do it. Here are the basement prices we had calculated from Gussek Haus for basement construction – (it is a smooth concrete basement, but they are not cheaper when ordered directly; we compared offers).

Guaranteed by the prefabricated house expert. He writes this in every other blog post. I actually find him quite knowledgeable, just his "Flo" is a bit confusing.

SandyBlack8 Feb 2022 06:31@WilderSueden Good instinct 😉 The argument was based on potential savings, but your explanation, @11ant, definitely makes perfect sense to me. If someone wants a basement and the prefab house provider doesn’t offer that – would that be a deal-breaker when choosing?
@blubbernase Thanks for the clear example. That’s incredible... Have you also compared with other providers? Are there any significant differences?
