What gets put up around Cape Town
Winter rain and the summer south-easter test every prefab building in Cape Town. Cold fronts drive rain sideways for days from May to September, so cladding joints, window seals and roof flashings have to be right, and the Cape Flats sand around Khayelitsha, Mitchells Plain, Delft and Philippi holds water when the table rises. Backyard rooms and wendy houses are a huge market there and in Gugulethu and Nyanga, while Southern Suburbs and Atlantic seaboard gardens add studios, home offices and granny flats. Salt air rusts fixings from Sea Point to Muizenberg. The city expects approved plans for anything lived in, and heritage areas have extra rules. Yards in Epping, Montague Gardens and Philippi supply most jobs.

In Cape Town, granny flats are asked for by:
- Homeowners: a cottage behind the main house for an elderly parent or a grown child
- Backyard landlords and families: a 1 or 2 bedroom unit on the plot let out for steady monthly rent
- Shops, offices and small businesses: a small consulting room or office unit beside a house, where zoning allows it
- Contractors and mines: a show unit or caretaker's cottage on a housing development while it is built
