On a Hout Bay smallholding, the house is usually the best-protected building on the property and the least likely to be anybody's target. What actually gets taken is tack, feed, tools, fuel and equipment, and those live in outbuildings secured with a hasp and a padlock chosen twenty years ago. Bringing three or four of those up to a proper standard does far more for a plot than anything spent on the main house.
The second thing worth doing on a large plot is a key plan. A property with stables, a feed room, a tack room, a workshop, a garage, a cottage and a main house will have accumulated locks one at a time, and typically ends up with a groom who carries nine keys and a household that cannot say what half of them open. A designed hierarchy gives each role exactly the access it needs and makes a departure a single, clean change.
At the harbour end the priorities are different again. Continuous salt exposure combined with heavy commercial duty cycles means ordinary hardware simply does not last, and the honest specification is corrosion-resistant, heavy-duty fittings rather than the cheapest thing that fits the hole. That is standard commercial lock repair territory, and doing it once properly is considerably cheaper than doing it annually.
