ᐅ Garage insulation cannot be installed

You can either do it properly now, or take another approach, but then it will just be... :P

The inadequate construction planning (if it was even possible to install the waterproofing before the neighbor’s paving and landscaping work) only makes it more expensive, but not impossible.

What else could be clarified:
What was agreed upon, and what is the architect actually responsible for? What do the detailed garage plans specify here (waterproofing, insulation) and why?

The property ends at the concrete wall of the garage. To dig, I would need access to the neighbor’s area.

Anyone planning a garage right on the boundary must check whether the neighboring property’s elevation matches accordingly.

Then the planner should prepare to restore that. If they fail to coordinate this properly, they should cover any additional costs.

That’s why I’m asking if something can be done from the inside.

No, as already mentioned in post #8, that is not possible. Leaving out the waterproofing against penetrating surface water precisely where it is most likely to occur (since, as you can clearly see, the water does not simply drain vertically but runs down the garage wall first) would be unwise. Trying to "trap" this trickle from the inside would only lead to a damp wall.

Structurally, I see no alternative to open excavation from the neighbor’s side. The insulation must be applied all the way down; there is no way around this. Look up “right to hammer” (hammering rights). You must exempt the neighbor from all costs, and your planner must arrange this before starting the external work on the neighbor’s property, especially if they overlooked it. The insulation can always be applied after the wall has been fully constructed—you should expect an architect to understand the spatial implications this has for a partially earth-retained garage.

You basically can’t access it from the outside anymore. Only from the inside some work could still be done.

Ladder and hammer rights apply here. Apparently, the architect is building their first house.
