Garage boundary wall made of exposed concrete, the rest made of bricks?

Hello everyone,

our garage was planned to be built from bricks (24cm). Now the general contractor suggests building the exterior wall towards the neighboring property (boundary construction!) from exposed fair-faced concrete. This way, accessing the neighbor’s property would not be necessary, nor would painting the wall in a few years.
What do you think about this? Sensible or not. I am a bit skeptical.

Exposed concrete quality is expensive. Concrete should/must be hydrophobized or painted. Are you already having problems with the neighbor? I wouldn't do it unless you really want exposed concrete.
