We are Scotch Score Holdings — building contractors based in Sandton, operating permanently across all Johannesburg Northern Suburbs. We handle the full process from architectural drawings and estate approvals through to completed construction. Part of our broader building extensions service across Gauteng.
Granny flats are in high demand across all Johannesburg Northern Suburbs due to strong rental markets and family-oriented neighbourhoods. We build complete self-contained units from R280,000 including plans, estate HOA and CoJ approvals and full construction. Rental income R6,000–R12,000/month depending on area.
Popular across Joburg North where property values are high but stands are small. Adding a second story costs R450,000–R850,000 — a fraction of what it would cost to sell and upgrade. We handle full structural engineering, first-floor slab, staircase and all finishes.
Extra bedroom, kitchen extension, home office or covered patio. Single room extensions across all northern suburbs from R90,000 including plans and CoJ approval. One contractor, one quote, full responsibility.
We have HOA submission experience across Dainfern, Blue Hills, Blair Atholl, Cedar Lakes, Clearwater and 30+ other Joburg North estates. Estate approval must happen before CoJ submission — we manage both so your project doesn't stall.
