What to know locally in Centurion
Light steel frame granny flats suit Centurion, where many estate rules ask for a plastered look and the frame is quick to erect once plans are passed. Office parks in Highveld and Hennopspark use prefab buildings and site offices for extra space or during construction. Schools around Kosmosdal and Olievenhoutbosch ask about prefab classrooms. On dolomite land, the base under any of these may need an engineer's sign off.
Sizes run from small studios to 2 bedroom units. Before you agree to anything: approved plans needed: it is a dwelling.
Prefab and timber building in Centurion
Dolomite under parts of Centurion matters more than the colour of the cladding: on some stands the council wants a geotechnical report or an engineer's foundation design before any granny flat or cabin goes up, and a light prefab building does not escape that. Estates such as Irene, Midstream and Southdowns often limit what can stand in a garden, so many owners ask for a neat wendy house or a plastered steel frame unit that matches the house. Olievenhoutbosch has strong demand for backyard rooms. Suppliers in Lyttelton and near the N1 and N14 reach most streets quickly. The Hennops River valley gets frosty, and summer storms from the south west bring hail and lightning.

Typical granny flats requests in the area come from:
- 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
- Schools and creches: a cottage on school grounds for a caretaker or a teacher living on site
