What to know locally in Randburg
Granny flats in Ferndale, Fontainebleau and Kensington B are often for students and young workers, and many owners rent them out. Steel frame houses suit plots in Northriding where owners want a quick, insulated build. Wooden cabins appear in larger gardens near the Klein Jukskei. Site offices serve retail and road projects around Northgate and Malibongwe Drive, and schools in Cosmo City ask about prefab classrooms.
Sizes run from small studios to 2 bedroom units. Before you agree to anything: approved plans needed: it is a dwelling.
Building prefab in Randburg
Sloping stands are the first thing to plan for in much of Randburg. Gardens in Northcliff, Blairgowrie and Linden fall towards the spruits, so a wendy house or cabin often sits on a timber deck with stilts or plinths rather than a slab. Ferndale and Bromhof have older family homes adding garden flats and studios, while Cosmo City, out to the north west, has a strong market for nutec backyard rooms and second units. Kya Sand and Strijdom Park hold workshops, timber yards and erectors, so supply is close by. Ridges like Northcliff take the brunt of lightning on summer afternoons, and hail can dent thin roof sheeting, so ask what gauge the roof is.

The requests we see from Randburg usually 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
