ᐅ Should a pathway be constructed if it is intended to be permanently covered with vegetation?

Hello,

I have purchased a newly built semi-detached house.

The houses are all built next to each other with garages in between.
There is a 1-meter (3 feet) gap between the two garages—1 meter (3 feet) for my neighbor and 1 meter (3 feet) for me.

I would like to install a garden gate in this gap, but according to the development plan, this strip must be permanently greened.

Now my question is:

What kind of path am I allowed to build so that I can walk alongside the garage while it still legally counts as green space?

The path should be low-maintenance (I don’t like grass because my robotic lawn mower can’t reach it).

Do you have any tips for me?

Grass pavers made of plastic or stone. Unless greening means more than just grass.

You can place stepping stones within a flower bed that lead to the garden gate. This likely won't cause any issues and can look very attractive. What do you plan to transport through the garden gate – just people, or also bicycles, trash bins, etc.?

This is meant to be an alternative entrance.

I would prefer not to install a back door on the garage (additional cost of 1500€) since access is restricted when the car is parked in the garage.

The alternative entrance is intended for people and bicycles, or for transporting large or dirty items into the garden.

Ideally, we would pave a path for this purpose.

Gravel lawns should also be feasible.

Unfortunately, you have to trim it regularly.

I have a robotic lawn mower that can’t reach that area because of the garden gate,
and since it’s only about 3 square meters (32 square feet), I don’t want to take out and store a lawn mower.

Are there any other alternatives?
