Are there any concerns with building recessed cabinets into a house/garage partition wall?

I have a mudroom in which I would like to add additional “reach into” storage above the to be installed bench. The reach into space would be provided by going back through the existing wall, in between the existing studs. This wall is load bearing, and is into the garage. I would not disturb the load bearing studs.

There is no apparent plumbing and only one existing electrical like that I can easily move to the side.

I would be in effect creating 4-5 “bays” of about 14” width that would correspond to each persons area for the mudroom above the bench. This would be for gloves hats shoes etc.

The found space would be achieved by adding a wall on the backside in the garage about 18” past the existing wall. This wall would be framed up appropriately, have vapor barrier, use fire rated drywall, and be sealed/insulated. So essentially I’m just creating a cavity for reach in space, so to speak, and adding a wall in the garage.

So, any unforeseen issues or considerations? Again the existing wall would not have the studs disturbed and the vapor barrier and insulation/fire code would be handled on the installed wall.
