We have a hillside property that is currently still developed. The slope is, to put it politely, quite steep.
For the existing buildings (garages, basement rooms, and stables), the hillside was excavated as much as possible at that time, and the buildings simultaneously serve as hillside support. Hopefully, this is somewhat understandable. We imagine it like this: on the ground floor at the back, a concrete wall = new retaining wall, and the other three walls are system walls from prefab house companies.
Provider 1: Solid wood with insulation on the outside sees no problem in building directly against a new retaining wall, not even with the sealing between concrete and solid wood wall on the upper floor.
Provider 2: Wood frame sees a long-term problem with sealing the connection between the upper floor system wall and the concrete wall. Therefore, he suggests building a retaining wall and, with a 1-meter distance, a house with 4 normal system walls.
We don't understand the problem that provider 2 sees. That would have to occur at every connection to a basement. Is there any truth to that?
We want a level, wheelchair-accessible front door and a wheelchair-accessible terrace door.
Provider 1 suggests a massive large canopy so that no water can be pushed into the house during wind and heavy rain.
Provider 2 considers that not a problem; if we think it would be, we should just install a small glass canopy.
Are there long-term problems with water penetration through barrier-free doors?
It would be nice if someone could answer these two questions. We are a bit confused because the opinions of the two differ significantly.
