What We Build — Extensions Across Fourways

We are Scotch Score Holdings — building contractors operating daily across Fourways and Johannesburg North. Whether you are in a freehold property, cluster complex or one of the major Fourways estates, we handle the full process from architectural drawings and approvals through to completion. Part of our broader building extensions service across Gauteng.

Granny Flats Fourways

Fourways has one of the strongest rental markets in Johannesburg North — corporate professionals, Lanseria Airport staff and students all drive demand. We build complete self-contained units from R280,000 including plans, estate HOA approval, CoJ permit and full construction. Typical rental income R6,500–R12,000/month.

Second Story Additions Fourways

Many Fourways homes were built on smaller stands 10–15 years ago. A second story is often the only way to add significant space without losing garden. We handle full structural engineering, first-floor slab, staircase and all finishes. Two bedrooms upstairs typically R450,000–R850,000.

Room Additions Fourways

Single room extensions in Fourways townhouses, cluster homes and freehold properties. Extra bedroom, home office, playroom or lounge extension — all done with full plans and CoJ approval. From R90,000 for a single room addition.

Estate HOA Approvals

We know the submission requirements for Blue Hills Estate, Blair Atholl, Estate d'Afrique, Cedar Creek and Fourways Gardens specifically. HOA approval must come before CoJ submission — we manage both so your project doesn't stall. Estate approval typically 2–4 weeks.

Architectural Plans & Permits

We work with registered architects and structural engineers to produce estate-compliant and CoJ-compliant drawings. We submit, track and follow up on your behalf. CoJ permit approval typically 6–10 weeks from submission.

Full Construction Management

One point of contact from design through to handover. We supply materials, manage all subcontractors and provide weekly progress updates. Every project includes a written 2-year workmanship warranty and completion certificate.
