Our local civil engineer will be installing material around us in the coming days and leveling the garden with the 110m3 of soil that is already there, for a reasonable price.
Advantage: on the neighboring property there are about 80 cubic meters of compactable excavation material that we can take for free. Otherwise, all heights will be established so that it will also fit for the paver later on.
Towards the neighbor (other end house) about 1.50m needs to be sloped. Whether it can stay like that when he excavates his basement will have to be seen.
