Drive north from here and the housing gets progressively newer, until you reach developments finished in the last few years. Drive into Milnerton and the housing is decades older, which matters practically rather than aesthetically: the cylinders, gate mechanisms, window fittings and door furniture in these houses are of a different generation from anything in the surrounding suburbs.
That produces a workload almost entirely absent from the newer areas. Original locks turned twice a day since the seventies, security gates fitted when they were still a novelty and never serviced since, and driveway installations from the first generation of automation. Very little of it is broken; almost all of it is worn, and worn is a cheaper problem than most owners assume — lock repair rather than replacement, a security lock upgrade only where a boundary genuinely warrants one, and an emergency door opening on the morning something finally refuses altogether.
The lagoon is the other local factor. Where properties face the estuary and the open water, the air carries salt and moisture in a way that the streets a kilometre inland do not experience, and outdoor fittings on that side age noticeably faster. It is not the full ocean exposure of a beachfront address, and it is enough to matter over the life of a gate lock or a padlock.
