Because one usually does not want to lead visitors through the entire house just to accept registered mail, or so that one does not have to run all the way down oneself.Why should one go outside on a staircase when one can also do this inside? It would even be ice-free in winter.
The stairs are closed in winter when there is ice. For us, this would have happened once this winter
I played around a bit again without any claim to meaningfulness due to lack of funds.
Besides, the inclined reader has to bring some imagination, as the partly difficult topography is not the strength of my ancient program. Stairs as always no landings. The "front garden" would still need to be extensively paved to connect all paths. Because of the slope, my program is refusing there.
The whole thing would, however, depend on whether the master bathroom can be drained. A specialist would have to rack their brain whether they can get through the ceiling into the hallway wall o
I agree with you, the 20 cm topsoil can of course be stored on the side. In the case of the OP, it is not a new development area. With us, during the development by the civil engineer, everything was mixed and only the rubbish was left behind.I would say: yes and no. The topsoil is actually not waste; according to the Federal Soil Protection Ordinance, it must not be disposed of but must be reused. In some places, you are lucky to find a thick topsoil layer suitable for agriculture, which is gladly taken over by a farmer or a neighboring builder for their garden. Completely legal.
If there is a clay layer underneath, it is usually disposed of, but it could also serve as a raw material for a brick or clinker factory.
And if there is a gravel layer below that, it can of course be reused in other construction projects.
In these cases, the excavation material would not be waste but a product and is therefore not disposed of illegally but reused.
However, most excavated material—at least in our region—is qualitatively unsuitable or too mixed to be reused. I just wanted to clarify that not everything a digger scoops up always has to go to the landfill.
