ᐅ Slope of driveway / elevation difference

Hello everyone,

We are currently still in the shell construction phase and unfortunately discovered on site over the weekend just how significant the height difference between the house entrance platform and the curb (street level) actually is.

First of all: Attached you will find pictures of our house entrance, as well as a cross-section from the house building plans and the entrance platform.

Street level: 559.96
Garage height: 560.18
Single-family house: 560.43

Problem: The garage is not being set at street level but approximately 40cm (16 inches) higher at the bottom edge of the stair step.
This means the 40cm (16 inches) height difference between the curb edge and garage (over 1 meter (3 feet)) is compensated for – resulting in a slope of 40% over 1 meter (3 feet).

At the moment, we are completely unsure whether such a slope is even feasible, or if it would be better to add extra steps at the house entrance to compensate for the height and thus set the garage at street level.

Originally, we did not want any additional entrance steps, but unfortunately, we do not see how to solve this problem otherwise.

Maybe we are just worrying unnecessarily?

We look forward to lots of feedback and support!!

Thanks 😉
