ᐅ Interpreting Zoning Plans for Sloped Sites (Beginner’s Guide)

Hello everyone,

we are beginners and about to purchase a sloped lot on a south-facing hillside (elevation difference north to south approx. 5 meters (16 feet)). The plot is located in Bavaria.

The supplement to the development plan allows for 2 full stories, but it must appear as a single story on the uphill side, while two stories may be visible on the downhill side.

The following notes apply to this parcel:
1. Eaves height on the uphill side 3.50 m (11.5 feet) above finished floor level of the upper floor
2. Finished floor level of the upper floor maximum 516.03 m (1693 feet) above sea level
3. The building may not have a basement.

The development plan and section look as follows, but unfortunately we cannot fully understand the ground floor.

Does the ground floor therefore have to be completely underground, is that what is meant by the “yellow” area, or how should this be interpreted?
Could, for example, the yellow area be exposed so that the “ground floor” is flooded with natural light from three sides?

Best regards from the building novices

What is written about this in the justification?

Without a legend, I can’t either.

Hello,

Regarding the legend:
The red dashed line represents the current slope of the terrain. The yellow area indicates the slope fill.

The development plan states the following about the fill:
The ground must be filled up to at least 40 cm (16 inches) below the finished floor level of the ground floor. Only natural stone retaining walls are permitted for this purpose. Walls may be up to 50 cm (20 inches) high with a minimum thickness of 100 cm (39 inches). Terrain modifications are allowed as slopes with a maximum gradient of 25° or in terraces with a maximum step height. The newly formed terrain must remain within this area. The permitted fill zones are illustrated and marked in yellow in the cross-sectional plan for each plot.

This raises some questions for us… From where is the 25-degree slope measured?
If the ground must be filled up to 40 cm (16 inches) below the finished floor level of the ground floor, which is actually below the floor level, doesn’t that contradict the 25-degree slope restriction? What exactly is mandatory, what represents the minimum, and what is the maximum fill level...

Our goal is to have as little fill as possible to allow for as many windows as possible on the ground floor, thereby creating “normal living space.”

Many thanks in advance for your feedback!

Best regards from Chiemgau

In my opinion, there is no contradiction. A friend of mine has a similar situation; he is only allowed to build two floors and has the south side of the ground floor and the west side of the ground floor free. On the east side, the garage is directly adjacent, which also has a ground floor. I don’t see any restrictions in the building permit / planning permission.

First, here is the legend for the cross-section drawing:

And to have everything together, here is the cross-section again:

and the text:

My interpretation is: Within the yellow area, you are allowed to shape the terrain. For your property, this is almost the entire plot—the yellow area ends only at the lower edge of the slope, where the natural terrain must be maintained.
The house itself must initially be built with at least 40cm (16 inches) of fill up to the finished floor level of the ground floor. The terrain shaping mainly refers to the remaining area around that.
Where you start modeling the terrain or whether you do it at all is up to you. The only restrictions are that you must not exceed a 25° slope or build retaining walls higher than 50cm (20 inches)—and those have to be natural stone, which is costly. Regarding width, I think the description is somewhat unclear. I assume the 1m (3 feet) refers to the depth of each step (but it could also mean width—worth checking).
Accordingly, you can calculate how much you can shape the terrain within your building area by either using retaining walls or a 25° incline.

With a 25° slope, you overcome a height of 3m (about one story) over approximately 6.4m (21 feet). Using steps, you can reach that height faster, roughly after 5m (16 feet), assuming the note about width/depth is correct. But it also depends on where your basement starts. Do you place it fully embedded on the slope side, or do you raise it somewhat? Your eaves height may be up to 3.50m (11.5 feet) (based on height line 516, which likely corresponds roughly to street level). Depending on the building depth and gravel (both figuratively and literally), your basement may be exposed on more than half of its sides. (Unfortunately, I can’t find the depth of the building area in the documents.)

Putting theory aside, it’s a very nice property but also expensive to build on. You should budget over 100,000 for earthworks and slope support—I would estimate closer to 130,000. Natural stone retaining walls are expensive.
