Maybe like this. Some water flowing into the land without filling. So from the street to the house initially downhill. You get rid of water through a gravel edge around the house and a drainage underneath, which you lead to the rainwater shaft or, if the soil permits, to the infiltration trench. Then the house with terrace as a slab and L-stone retaining wall at the hedge. But only the house and terrace, the rest of the land you leave as is, just slope the soil to the terrace. That way you have a lot of area that absorbs water through plants and only as much earthwork as necessary. And you can visually benefit partly from the neighbor’s hedge, which already saves you the fence.
