ᐅ Development / Layout of the Adjacent Rear Property

Hello everyone,

I am facing the following challenge:
In Baden-Württemberg, we want to convert a rear garden plot (surrounded by houses) into building land. The application has already been submitted to the district office in Tü and should be approved by May.

Once that is confirmed, we want to start planning a single-family house. This requires designating two parking spaces.
We are currently preparing how to divide the plot since we have some limitations due to the access.

Basic data:

- Plot size is 27 x 18 meters (89 x 59 feet)
- House should have 2 full stories and about 160 - 180 sqm (1,722 - 1,938 sq ft) of living space (no basement)
- Currently planning roughly 12 x 9 meters (39 x 30 feet)
- Garage (or carport) at least 6 meters (20 feet) long. We have only one vehicle (5.20 m / 17 feet long) but need to allocate two parking spaces. It’s possible we’ll get a second vehicle later.
- We definitely want a shed / garage extension ideally connected to the garage.

In the attached image (Grundstück.jpg), you can see the plot cleaned up with Photoshop from above. Access is only from the west side and is currently planned to be 3 meters (10 feet) wide.
It is the plot marked in red.

There is no binding development plan or building envelope. This means it must fit the surroundings and keep at least 2.5 meters (8 feet) distance from the boundaries.

I have already developed about 10 variants on how to arrange the buildings.
I have also attached my 4 favorites.

V1:
House 12 x 9 m (39 x 30 ft)
Garage 6 x 6 m (20 x 20 ft)
Shed 6 x 3 m (20 x 10 ft)

Positives:
- Garage and shed are neatly arranged.

Negatives:
- House is not square and might be difficult to design with a gable roof.

V2:
Positives:
- Large courtyard for the children.

Negatives:
- Garage is far from the house.

V3:
Positives:
- Garage and shed are on the northeast side, so they avoid midday sun. However, the office and guest toilet would have no windows or only face the garage (according to the current planned layout).

Negatives:
- Feels like almost the entire plot is paved, which would also increase costs.

V4:
Positives:
- You could use either the carport or the garage for something else as long as you only have one car.

Negatives:
- Takes up a lot of space.

I am really getting frustrated because I would like to decide this myself and not wait for what the architect proposes.
I would like to have the layout finalized already.

Can you help me here? What would you do? Or do you have other ideas?
Is it possible to designate only one parking space, or two smaller ones? Or should we position the house differently? My head is really spinning 🙂

Best regards,
Samuel
