Hello,

Has anyone here built a house without a basement on a slope? I would appreciate some pictures to get a better idea. We have an elevation difference of about 5 m (16 feet) from the street to the property boundary, which is approximately 25 m (82 feet) away, and the finished floor level (FFL) is planned to be 1.66 m (5.4 feet) above the street, with the garage 0.5 m (1.6 feet) lower.

I’m really having trouble imagining 1.66 meters (5 feet 5 inches) above ORF... How much fill are you planning to bring into the excavation? And that’s going to create a huge height difference towards the garden.

I am adding a few pictures of the planned house on our property.
The garden will be created in two levels.

Two-story single-family house with attached garage on the left, entrance at the front, gable roof.

Yes, but not quite that extreme.
Especially, why are you designing the house that way? That approach is more suitable for a flat plot of land. You’re spending a fortune on excavation and retaining the land just to create shade.

When the surveyor measured the plot, the house was already planned, and redesigning everything afterward was quite time-consuming and costly (which I now regret).
Within the building area, we don’t have to remove much material, and according to the soil report, we don’t even need to install strip foundations. The actual slope starts from the terrace :/
On site, it doesn’t look like there is a 5 m (16 ft) height difference; we thought it might be about 2.5 to 3 m (8 to 10 ft).

Honestly, building on a slope is not easy.
I would consider redesigning. The terrace won’t look nice and bright when it’s squeezed between the house and the slope.
It’s nice to have a view of a section of green wall, but not just that.

Make sure the driveway to the yard/garage is not too steep. Also, plan a path for wheelbarrows and similar equipment to access the terrace.
