Hello everyone,
We have been working for some time now on how best to position our future single-family home on our plot. We want to utilize the existing slope as efficiently as possible and avoid losing too much green space.
Development Plan / Restrictions
Plot size approximately 700 sqm (8,400 sq ft)
Slope: yes, 10% south-facing slope
Site coverage ratio (Floor Area Ratio) 0.3
Floor space index 0.6
Number of parking spaces: 2 (garage or carport)
Orientation: Ridge direction can be freely chosen
Maximum heights / limits: The eaves height on the valley side must not exceed 6.65 m (21.8 ft)
Maximum 2 full floors
Setback distances according to the regulations of the Bavarian building code
Attached garages to the boundary are only permitted where garages are built together within the areas designated in the development plan
For other garages, a minimum distance of 1.20 m (4 ft) from the property boundary applies
Client Requirements
Approximately 150 sqm (1,615 sq ft) of living space
Basement, floors: open. However, due to the slope, a basement is likely. Possibly using the basement as a garage.
Number of occupants, ages: 2 adults, 2 children
House Design
Designer: Do-it-yourself
Could you please provide some input on the preliminary planning of a single-family home?
The building site has a south-facing slope of about 10%.
The road is located on the north and west sides.
I have already marked the key points by laser. Zero point at northeast. The measurements are given in centimeters and should actually be negative since it is a south-facing slope.
The plan is for a single-family home of about 150 sqm (1,615 sq ft) with a garage or carport.
Option I a
5 m (16.4 ft) from north and west
House approximately 10 x 10 m (33 x 33 ft)
Garage integrated into the basement. Driveway access from south/west.
Guest entrance on the north side.
Advantage:
Everything fits within the 10 x 10 m (33 x 33 ft) footprint.
Disadvantage:
The garage driveway must be in front of the house, which results in a substantial loss of green space since there is only 7.5 m (24.6 ft) width available on the east side.
Option I b
House is positioned 5 m (16.4 ft) from north and east, leaving 7.5 m (24.6 ft) on the west street side. However, the driveway to the basement garage would definitely be too steep here.
Option II
Build the basement slightly higher and place the sleeping and bathroom areas in the basement so that the garden can be accessed directly from this level.
The upper floor has the main entrance on the north side, accessed by several steps. This floor contains the kitchen, dining, and living areas.
The garage or carport is built beside the house.
There is a balcony terrace on the upper floor, accessible from the dining area. The garden is reachable via stairs.
Advantage: Much more green space remains on the south side.
Disadvantage: Significantly more earthworks required. Overall less green area preserved.
Similar properties in the neighborhood:
2 full floors + basement + garage: In my opinion, the basement is only used as unnecessary storage space here. The costs are too high for this.
Slab foundation + 2 full floors + garage: Due to the slope, this requires extensive earthworks.
Attached are the height measurements, sketches of the options, and an excerpt from the development plan.
I would appreciate any input or other ideas very much.

Access and driveway from the north, as a garage will be located there.
Ground floor: children's room, bedroom...
In the basement, the living room, dining area, and kitchen with direct garden access, placing the kitchen in the area that receives less light due to the sloping ground.

There was a bug in my post.
Plot measures 25.4 x 22.8m = 572sqm (Northwest corner is rounded).Are the 700sqm no longer valid? I’m a bit concerned, a rounding wouldn’t account for 130sqm, more like 13sqm. Usually, one knows the size of their plot.With a 10% slope, I don’t see any real possibility for a basement at first.
With a house depth of 9 meters, that would be a difference of 90cm (35 inches).
But you could argue that you’d level the garden a bit anyway, moving higher soil to where it’s needed (earthworks). This would bring the area near the house to a lower level, which would justify an underground floor replacing an attic. Typically, you would have a two-story house, since without windows on one side, you would need more space elsewhere.
As for a garage outside the house: nobody wants it in the garden or to have a driveway there if it can be avoided. Also, the Renewable Energy Act practically prohibits this idea already.
I’m of course also considering placing kitchen and living areas in the basement to justify a terrace and save the need for a balcony.

hanghaus202331 May 2025 11:52According to the garage building plot, no boundary construction is allowed. The option with the garage/parking space in the southwest is also not possible.
Although the house orientation is not ideal according to the development plan, it is more acceptable given the slight slope.
Is the slope on the property also uniform further down? This information is missing.

You would need several winning lottery tickets just to cover the crime scene mansions from a single season of Rosenheim Cops.That’s exactly the kind of source I mean. During a creative phase, you don’t judge but collect ideas. Often, you discover what exactly appeals to you about an image and realize that you can implement that aspect in a different way that fits your budget. It’s a pity when people miss that opportunity. For most individuals, building a house is the most financially significant investment in their lives. From my perspective, it’s worth looking beyond the standard solutions by exploring options from different angles and even from the inside. Standards are useful for functionality—but life is about more than just fulfilling “functional” requirements. Even if the result of such a process is a house that looks “normal,” at least you can be sure that this version of normal suits your own life.
For me, it was too risky not to explore some more unconventional ideas. But as the people from the Rhineland say: everyone is different.

According to the garage’s building plot, a boundary wall is not allowed. So what? If I consider the credible height of about 25.5 meters (84 feet), then a garage is allowed to be built just one meter (3 feet) from the property boundary. If you change the garage into a carport, you can still easily open the car door within that one meter (3 feet) of space. That’s what we have as well.
But even if a garage is necessary, living with the “lost” meter (3 feet) next to it isn’t a problem—you can place the wheelbarrow at the rear end or the trash bins beside the front end.

Where does the Renewable Energy Act prohibit a separate garage? This was referring to the statement that the original poster wanted the garage inside the house, arguing it’s because of the slope, so the garage in the basement.
So driveway in the garden, because it’s a south-facing slope: No! Garage inside the house: No.
