By loggings I assume you mean the wooden houses clash with with brick buildings ?
You could remedy the clash by adding brick areas for the foundations of the wooden buildings
But then...
The brinks might get a bit monotonus
and adding wooden details to the brick buildings (like supports, wooden ramps, maybe a wooden office attached to one side, etc).
well, to an extent I am already doing this, and I'll do some more, but not on all buildings. The somewhat big brick warehouse that hosts cap A just doesn't need wooden parts, and what will probably serve as a facade for the spytech in C will most likely be the same. Also, wooden supports for brick buildings would just look wrong imo. Brick doesn't really need support, and certainly not from wood.
EDIT: actually I just found
an example of this, but it's not really the style of building I am shooting for.
Basically, the general idea was, there is an old industrial site (paper mill ?) with major structures made of brick, and then there are minor structures and accomodations that developped around it and are made of wood since there is plenty of it available for construction.
For the button, well it's really no more or less accessible than the one in well. I guess you could almost catch it if you were to remove the wooden panel in the top-right and stand there. You'd probably need some form of pole to catch it anyway and then the wire will just extend as you pull ?
