ᐅ Rural Land – Which Type of Plot Suits Which Building Design – Building Regulations

Hello everyone, my wife and I have reserved a plot of land in a rural village (Baden-Württemberg). We are very interested in building there since we come from this region. We have taken a closer look at the local development plan and find the regulations quite strict. We are currently trying to find a sensible solution. First, here are our requirements:
- Living area approximately 150+ square meters (with at least 3 children’s bedrooms)
- We definitely want a basement (initially not for living, possibly later 1-2 rooms with natural light due to a slight slope)

We have already considered various points on how to implement this—especially how to maximize living space with minimal additional costs for features like bay windows or dormers.

At this point, we have settled on a pitched roof to make at least part of the upper floor usable.

Do you have any ideas if this could be done, for example, with a flat roof? (Unfortunately, we are not trained architects and can’t fully understand what requirements must be met to build a flat roof at 6.7 meters.)

We appreciate any help and support to make our dream come true! Thank you in advance for your assistance!

Development Plan / Restrictions
Plot size: 699 square meters (sqm), number 39
Slope: yes / cross-section currently not available
Site occupancy index (Grundflächenzahl): 0.2
Floor space index (Geschossflächenzahl): 0.2
Building envelope, building line, and boundaries: no specific regulations—only those from the building code (Bau VO)
Edge development
Number of parking spaces: 2 (we do not want a garage)
Number of floors: 1
Roof types allowed: gable roof / pitched roof with dormers / hipped roof with slope 22° to 30° / flat roof 0° to ≤ 5°
Architectural style
Orientation: toward the street or cardinal directions
Maximum heights / limits
Additional specifications:
- 1 full floor with site occupancy index and floor space index 0.2 (our plot has 700 sqm)
- Ridge height 6.7 meters (The maximum building height is defined as ridge height—the highest point of the structure. This is measured from the reference level at the ground floor’s finished floor height (single-family house). Maximum ridge height = parapet height for flat roof.)
- Eaves height 3.5 meters (Eaves height is measured at the highest point where the outer wall meets the roof covering or flat roof, starting from the designated reference point (single-family house).)
- Reference point: ground floor finished floor height (single-family house). All building heights are measured relative to the single-family house level. The ground floor is the full floor according to § 20 of the Building Use Ordinance. Excavations and fills required to achieve the chosen ground floor height are permitted.

Homeowners’ Requirements
Style, roof shape, building type: basement with living space (approx. 50%)
Basement, floors: basement + full floor + attic
Number of occupants, ages: currently 2 x 25 years old plus possibly 3-4 children in the future
Space requirements on ground floor and upper floor:
Office: home office and my wife is a teacher
Occasional overnight guests per year: 5
Open or closed layout: indifferent
Conservative or modern design: indifferent
Open kitchen, cooking island: yes
Number of dining seats: 6
Fireplace: yes
Music or stereo wall: no
Balcony or roof terrace: yes
Garage or carport: no
Utility garden or greenhouse: no
Additional wishes / special features / daily routines, also reasons why certain things are wanted or not

I hope these details are sufficient to work with. It’s possible we might change the plot again, but we really like this one because the meadow across the street cannot be developed, giving us a relatively wide view over the valley!

Total budget excluding land: approximately 450,000 euros (and yes, we are willing to do some work ourselves)

(If more information from the regulations is needed, I can provide or link to it if allowed 🙂 )

THANK YOU in advance for your support!!!!

Allowed only within the forum. Otherwise, you name the development plan with location, name, and number (just as you commendably did here, without the otherwise "usual" childish erasures).

Ok, I hope you can work with the information provided for now – for some reason, I was unable to upload the PDF!

Thank you for your efforts!

Then upload the graphic in two or three parts, or separately upload the right section with the texts. They are impossible to read.

I hope it is readable – THANK YOU

No, you can’t do that. It’s not enough to just cut out the section from the existing graphic... I could have done that too. It needs to be specifically rescanned and saved immediately at the appropriate resolution... or you could provide the keywords so I can search for it myself.
