Hello everyone!

I have been in the planning phase for our single-family house for some time now, but it is proving to be very difficult and complicated due to the characteristics of our plot.

Here is a brief description of our plot:
Orientation: South - North
Dimensions: 20m wide and 40m long (approx. 66 feet by 131 feet)
The access road is located on the south side. Therefore, our plot slopes upward about 3m (10 feet) from the south (access road) towards the north.
See attachment below:

We do not have a preferred layout for the floor plan of the single-family house. I am open to all ideas and would appreciate any suggestions or layouts that could help us realize our dream home. We have already considered all variants (basement & ground floor, ground floor & upper floor)…

What we want:
- Double garage and barrier-free access through a utility/mudroom into the house & a technical room for the building
- Basement / Ground floor:
Living room
Dining room
Kitchen & pantry/storage room
Office
Bathroom
Toilet
Entrance hall & cloakroom
Access to the next floor via stairs

- Ground floor / Upper floor:
Master bedroom
Child’s bedroom
Child’s bedroom
Child’s bedroom
Bathroom
Toilet

Roof type: Gable roof

South orientation is not a must, as we are not sun worshippers and summers are getting hotter. We want nice, open, and bright rooms, as well as a garden on both the south and north sides with small terraces.

I would be very grateful for your help, thoughts, and experiences, and I look forward to hearing from you!

Best regards from beautiful Austria!

We want to be able to enter the house from the garage completely level.

Garage in front of the house: (preferred option)
In my opinion, these two statements contradict each other. Or how do you plan to get from the garage in front of the house into the house? Elevator?

That's right 😀

The garage should always be connected or attached to the house! Regardless of whether it is in front of or behind the house.
The garage should always be attached to the house.

I hope I have described it better now...

Sorry, not really. How do you plan to overcome the height difference if the garage is in front of the house?

Yes, that’s correct. Of the 20m (66 feet) width, I can only build on 14m (46 feet) effectively. The 3m (10 feet) setback from the property boundary must be observed.
Our plot measures 20x40m (66x131 feet). After deducting the setback areas, we are allowed to build on 14x34m (46x112 feet).

The dimension arrows are just very awkwardly placed.

The bold red arrows are very clear though. I just wanted to mention it.

I don’t understand either. You can’t just make the slope disappear.

That’s why I’m asking for your input on the best way to position the house and garage, and how to best handle the elevation change. The site can of course be excavated.

I’m very grateful for your suggestions and advice to help solve this issue! Fundamentally, the goal is to create a level surface. We don’t mind where the garage is located... the aim is to get the best possible result in terms of cost, usability, and functionality.

Where? How much?
A slope remains a slope. Excavating or filling usually costs more than expected. The resulting retaining walls are necessary, and managing rainwater drainage often adds extra expenses. Achieving an effect with two terraces (south and north) involves massive amounts of earthwork. With a total budget of 650,000 and three bedrooms, an office, and everything else, in my opinion, this is unrealistic. Furthermore, my focus would definitely not be on directly connecting the garage to the house, but rather on minimizing costs related to land grading and fitting the required rooms inside the house.

I would recommend choosing one terrace, either south or north, and orienting the house accordingly. The north terrace offers the advantage of short paths (every square meter costs), summer shading (exactly when you want to be outside), and protection from the street by the house itself. After that, you can consider where the garage could be located.
