For rough location sketches, you would need the exactly measured plot including any building envelopes, distances, or other development plan specifications. Contour lines were already somewhere, I saw.
The contour lines are relatively inaccurate, we have completely surveyed the plot on a grid of 4.5 m x 3 m. I can gladly compile the information (at the latest by the weekend).
If I remember the operating and workplace ordinances from my apprenticeship
There is a significant difference between employing staff or not.
That sounds like the perfect recipe for a disaster first floor.
I see it similarly, then there would be significantly more restrictions. The static calculations and the resulting statics strongly depend on the construction method used, i.e., accordingly, one would have to accept further restrictions due to the construction method before planning.
I ask again, where is the construction taking place?
In Bavaria in the larger area around Regensburg.
Do you plan to do the carpentry work yourself?
That would certainly be possible. The garage would generally also not be a big problem if it were not for the green flat roof... Perhaps a change to photovoltaics as an independent roof covering could be considered... (that would also be allowed according to the development plan). I am happy to receive inspirations on this as well. Recently, I heard of a green metal roof where the greenery is located between the individual standing seams.
no ground-level exit
How do you want to bring the material from the street into the workshop? Do you never want to use a crane or something similar?
In my design, two large doors are planned in the basement on the south side. A gate in the fence allows relatively close access to the workshop.
load-bearing supports
No questions, certain ones are definitely needed. These must then be drawn in according to the specifications of the structural engineer. That, in turn, depends on the construction method and the load above. However, the supports can certainly be managed, I am not too worried about that at this point.
150 sqm living space * 3000 euros = 450,000 + 50,000 garage + 150,000 basement + landscaping 50,000 = 700,000
If the garage is postponed to later or completely done as an owner’s work, one would already be somewhat closer to the 650,000€. Some savings might also be possible with the landscaping since agricultural equipment is available. So if one were cautiously optimistic now, one could say that it is theoretically feasible with some compromises and a lot of owner’s work.
Here is one variant. This provides access to the workshop from the south.
Thank you very much! You really make an effort, we appreciate that. Since costs are often discussed, where exactly are the cost advantages seen here? Is it because less earthwork has to be done? As it is presented, I assume stilts with point foundations? How high is the additional effort for the extra base slab (or floor of the house)?
So I’ll briefly summarize fundamentally: the shown floor plan needs significant revision overall and financially is borderline in combination with the slope and the garage. Including the requirements for the basement finally blows the budget. The question remains: Are you willing to make compromises in the basement or slim down the workshop, etc., or can you massively increase the budget (will a bank still cooperate and would that be possible with children or would the desire for children have to suffer and the house would have to be planned smaller again?) and are you willing to put that much money into the workshop basement?
Thanks for the summary, compromises are tolerable in certain areas, but based on current knowledge we do not yet want to completely abandon all wishes (workshop wishes). Regarding the budget, we will definitely reconsider over the weekend. I thank you all for your answers already. During the week we are unfortunately not quite as quick to respond...
