On the ground in Johannesburg
Fibre cement boards and sandwich panels are sold from yards in Booysens and along Main Reef Road, and most suppliers can cut and deliver. Slab contractors in Soweto pour bases for rental rooms and quote per m², so ask about the damp proof membrane. A plan drawer can prepare council plans for a granny flat. Repair teams reseal timber wendy houses dried by the sun and replace cracked nutec panels after hail.
Building prefab in Johannesburg
Soweto backyards explain a lot about prefab demand in Johannesburg. Behind houses in Orlando, Diepkloof, Meadowlands and Protea Glen, owners put up nutec rooms and timber wendy houses to rent out or to give a grown child a space of their own, usually on a slab squeezed between the main house and the boundary wall. In Melville, Westdene and Kensington the request is more often a garden studio or granny flat that has to clear the council plan process and sit quietly beside an older house. Erectors work out of the industrial strips along Main Reef Road and in Booysens, so delivery is short. Highveld hail and lightning arrive on summer afternoons, so ask about roof sheeting thickness, gutters and earthing.
