Two solutions, and a substrate that decides between them
Retrofit reinforcement keeps your door: a steel skin dresses the leaf, angle sections protect the frame, a lock throwing several points replaces the old one, anti-lift pins are added. A full armoured set replaces everything — leaf, frame, lock, hinges — and its resistance no longer depends on the original joinery. The choice turns less on the door than on what surrounds it — and in Rillieux-la-Pape that runs from the pisé of Le Village to the concrete of Les Semailles.
In Le Village and at Crépieux-la-Pape the wall and the frame decide. Pisé, rubble stone and courses of river cobbles behave nothing like concrete, so the substrate is sounded before anything is proposed: reinforcement fixed into crumbling masonry throws the whole load back onto its own anchor points, and those points are only as good as the wall around them.
On the plateau the 1960s structures hold well, but refurbishment has in places added an insulated dry lining in front of the load-bearing wall, and a fixing that stops in a board holds nothing at all. The openings also keep their period dimensions, and an armoured set still has to come up the stairwell before it reaches the landing.
Who decides about the door, before anything is ordered
Rillieux-la-Pape is not a protected heritage sector, so the visible face of a landing door is not a matter for a conservation architect here, but for the co-ownership rules or for the landlord. That is good news for the choice of finish, provided the question is asked before the order rather than after the fitting.
In social housing on the plateau, the landing door belongs to the landlord's stock. A written request avoids unpleasant surprises: some landlords allow reinforcement, others impose their own replacement programme when the block comes up for works. The refurbishment timetable for your building therefore belongs in the discussion, since a door reinforced months before a scheduled refit would come straight back off.
In the houses of Vancia, Le Village and Crépieux the weak point is rarely the front door. The gate, the service door, the outbuilding open onto the courtyard and the garden window all come first. Reinforcing the main entrance alone moves the problem rather than solving it, so the survey covers every way in, and an open courtyard is dealt with before the leaf itself.
