House design
Who created the plan: architects and clients
- Planner from a construction company
- Architect yes
- Do-it-yourself
What do you particularly like? Why? in the optimization phase
What do you not like? Why?
Price estimate according to architect/planner:
Personal price limit for the house, including equipment:
Preferred heating technology: photovoltaic + geothermal

If you have to do without, which details/extensions
- can you do without:
- can you not do without:

Why has the design become what it is now? e.g.
Standard design from the planner? no
Corresponding/which wishes were implemented by the architect? yes
A mix of many examples from various magazines...
What makes it particularly good or bad in your eyes?

What is the most important/basic question about the floor plan summarized in 130 characters

Have read many posts and am very glad about such a forum.
We are still in the optimization phase, optimal use of the area.
We also want to make use of the slope location.
It will be a semi-detached house, our half is about 80 cm wider.
Base height 25 cm above reference height planned, thus the clear height on the ground floor can be increased to 2.80 meters, first upper floor 265 cm.
The weird beams serve for clarity regarding the slope location.

Looking forward to feedback.

Best regards

Don't quite understand yet: Is the plot a total of 715sqm or just your part? Why are you planning your partner's part as well? How does the partner actually get behind his house?

Hang 1m

Your bars don’t work for us. Maybe you should upload a manual site plan with the slope layout.

Grundflächenzahl 45 Geschossflächenzahl 30

This doesn’t make sense to me either: floor area ratio and plot ratio are given as 0.x. Or are there modern reforms that I haven’t noticed?

Anzahl Stellplatz 4x

The house side on the right side of the plan only has one actual parking space. Blocking in, especially with such a long driveway, doesn’t work for the authorities and also not practically.

Es wird ein Doppelhaus, unsere Hälfte ist ca 80 cm breiter.

Which one is yours? I find the plans quite confusing. Dimensions are missing. And what about the slope regarding the basement? Attic: where does it start (without counting the little boxes now)? And does it go over both halves of the house? Don’t the side dormers break the eaves height? I know it such that dormers need a minimum distance to the gable, otherwise they are not dormers.

Now I have also found the upper floor :) So: the attic shared by both parties doesn’t work because of the fire wall. Or it becomes a two-family house. In any case, for a semi-detached house the dream of paradise under the roof doesn’t work. About the design itself: - The garage planning and outdoor facilities are terrible. - Many "beginner dreams" are either not feasible or not functional. For example, one children’s room has no view (only double casement windows), while the bedroom gets a full front south-facing exposure, which you don’t really need for sleeping. - The ground floor is broadly okay if the basement cooperates - Statics were not considered at all. - The cost factor was not considered.

Floor area ratio 45
Plot ratio 30

I don’t understand that - please show the original usage template.

I have read many posts

Well, apparently at least my eternal broken record that you shouldn’t plan semi-detached houses because from sums ...

We also want to use the hillside location.
It will be a semi-detached house, our half is about 80 cm wider.
Plinth height planned 25 cm above reference height, so that the clear height on the ground floor can be increased to 2.80 meters, first upper floor 265 cm.
The strange beams serve as an overview with regard to the hillside location.

The strange beams “serve” as an overview, to put it kindly, “not” for us - and if the section drawings are correct, I wonder where you see a usable hillside location there. Why it should be an advantage for the clear height of the ground floor to start above the reference height is beyond me - as expected, the effect is the opposite.

The “dormers” are on the one hand cross-gables, and on the other hand also beyond what contemporary development plans usually prescribe in terms of width. That their position on the gables is probably also detrimental to exemption was already noted.

Did I count that correctly? The semi-detached house is 9m*13m
