Anti-drone cages, short corridors and small houses: how better design can solve British prison problems | Alex South

Alex South is a former prison officer and author of the memoir Behind These Doors .

He says prison design can drastically change the living conditions for inmates and the working conditions for staff.

Modern prisons need short, wide corridors that ensure a clear line of sight.

They also need CCTV , anti-helicopter wire and geofencing that can deter drones.
