Warwick Grey went to uMhlanga for a family holiday and found something The Common Sense has been documenting across South Africa: an enclave. Not a gated estate: a world-class public beachfront, open to everyone, run and paid for privately: 57 properties, 3 000 members, 12km of public space, 78 permanent jobs, and two-thirds of the money going to lighting and security. Warwick tells Gabriel Makin about the enclavisation he saw in uMhlanga.
