Balcony, roof terrace: Roof terrace in the attic for accessory apartment 1
Garage, carport: 3 garages, 2 parking spaces
Utility garden, greenhouse: A level garden is planned on top of the garages, with lawn and some bushes around.
Other wishes / special features / daily routine, including reasons for preferences:
  • Ground-level family access via garage and ramp into the basement. Guest entrance on the right side into the ground floor.
  • Separate external staircase leads directly to accessory apartment 1 in the attic. This unit also has a private entrance from above (north side) with garage and parking space (see site plan).
  • Accessory apartment 2 has direct access from the private driveway to the basement and the garage at the left property boundary.
  • Since we are a large family, laundry is often left in the living room. This should change, so we want a generous utility room (with marked ironing board) on the ground floor and possibly an additional ventilation system.
  • The private driveway is used only by us and one other neighboring property behind us. The surroundings have many trees, so there is no real view.
  • Large sliding glass doors from the dining room to the terrace/garden.
  • Good soundproofing between attic / upper floor and ground floor / basement.


House Design
Designer: Do-it-yourself
What do you especially like? Why? Plot with significant slope but still a level garden on top of the garages. Accessory apartment 1 with separate entrance from above.
Personal budget for the house, including outfitting: 1 million EUR in a major city in Bavaria
Preferred heating technology: Heat pump with photovoltaic system on the roof facing southwest
If you have to make compromises, which details/features can you do without: Gable window in the attic
Why is the design the way it is? We want to use the (expensive) plot as efficiently as possible.
What is the key/basic question about the floor plan in 130 characters? Where are the mistakes? Suggestions for improvement? Is the plumbing for bathrooms and kitchens sufficient or should I redesign it?
Unfortunately, I can’t accurately represent the terrain in the design software. If needed, I can scan a section drawing to make it clearer. The garden to the left of the house and above the external staircase will certainly be designed differently later. So far, there is no lawn area marked yet.

Many thanks in advance for lots of inspiring ideas

Is the 13% slope correct?
A 13% slope means 1.3 m (4.3 ft) per 10 m (32.8 ft) of building depth?

What is the purpose of the private road to the south?

Thank you for the note, haydee. 13% is not correct; it is about 27% at the steepest point!

The private driveway to the south provides access to the property. On the other side of the private driveway, there is an additional parking space, as shown in the very first overview image.

Do you have the exact elevation profile?
You are digging the house into the hillside, which will be quite expensive.
You are planning to have a large private driveway on the south side.
I don’t like the location on the property.

Have you considered swapping the sleeping and living areas?
Especially if the roof terrace doesn’t work out as planned?

I interpret this as meaning there is no public road at the end of the property on the hillside.

Attached are the exact elevation details of the plot.
The private driveway has always been this way and cannot be changed since it serves as the main access route for two other properties.

We do not want to swap the living and sleeping areas because we want the living area to have direct ground-level garden access facing southwest.

The private driveway is located at the end of the valley and also has a slight incline.
