Local tips for Sandton

Most asked for in Sandton: timber garden offices, pool houses and granny flats; rooms in Alexandra. Where the yards and builders are: erectors and timber yards in Wynberg, Marlboro, Kew and Kramerville. A useful tip: ask whether the crane truck can reach the garden, or if the unit is built on site.

Around Sandton the largest group asking is homeowners, which usually means a cottage behind the main house for an elderly parent or a grown child. On the weather side: summer hail and lightning, falling branches from big trees, frosty winters.

On the ground in Sandton

Granny flats in Hyde Park, Inanda and Atholl are often built in light steel frame and plastered to match the main house. Schools along the Rivonia and William Nicol corridors ask about prefab classrooms and halls for temporary space during building work. Office towers rising in Sandton Central and Sunninghill use site offices on skids, set down in tight spaces by crane truck, often on weekends.

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 Sandton

Large gardens in Bryanston, Hyde Park and Morningside give Sandton its own kind of prefab request: a pool house, a timber garden office, a staff room or a granny flat for a parent, finished well enough to sit beside an expensive house and passed through the council plan process. Complexes in Sunninghill, Lonehill and Rivonia have less space and stricter body corporate rules, so a small wendy or a storeroom is often all that is allowed. Alexandra, beside the Jukskei River, is a different picture, with backyard rooms on tiny stands and narrow lanes. Delivery comes from Wynberg, Marlboro and Kew. Old oaks and jacarandas shade many plots, which helps in summer but drops branches in storms, and hail and lightning are common.
