The right level before the right wall
The first question here is not which wall to drill into but at what height to install. The low-lying parts of the town know the Garonne's floods, and a basement, a garage or a ground-floor utility room combine every drawback: permanent damp, a risk of water, and easy access from outside for anyone with time on their hands. Family papers, notarial deeds, digital media and insurance policies age badly there, when they do not simply become unreachable at the worst possible moment. An upper floor, or at least a dry space, is a great deal better.
Then comes the support itself. In older buildings, stone and rubble masonry allow a safe to be recessed, provided you open up a wall that genuinely carries load and not a partition added when a flat was divided up — a common case above shops. In the houses on the outskirts it is the other way round: hollow blockwork and plasterboard linings, but a decent slab on the ground floor. There we favour bolting down to the floor, with fixings chosen for the material that is actually there and not the one you assume. An unsecured safe can be carried off by two people.
Market takings, business files: what gets locked away here
For a shop in the centre, the safe is installed around a routine rather than around a wall. Market days concentrate cash takings, and the trip between the till and the safe becomes the most exposed moment of the day. So the unit is placed out of sight of customers, in a room with controlled access, and knowledge of where it is stays with the people who need it. A deposit slot allows it to be fed without opening it, which limits exposure.
Another need that is very present in a service hub: keeping something other than money safe. A practice, a notary's office, a farm or a wine estate hold files, spare keys to buildings and vehicles, and digital media whose loss costs far more than their market value. In every case, start by rereading your insurance policy: it is the policy that sets the amount covered, the grade expected and the fixing conditions, not the product sheet. The invoice given to you after installation documents what was done.
