Room additions, granny flats, second storeys and home extensions across Cape Town. CIPC registered. NHBRC enrolled. Council plans included. Written contract. From R85,000.
Most building extension contractors in Cape Town operate without NHBRC enrolment, without council-approved plans and without a written contract. The City of Cape Town can order any unapproved structure demolished at any time. No bank will finance it. No insurer will cover it. You cannot legally rent it out.
Scotch Score Holdings is different. We are a fully CIPC-registered, NHBRC-enrolled, CIDB-registered building contractor operating across all Cape Town suburbs — from Bloubergstrand and Table View in the north to Constantia and Tokai in the south. Every extension we build is council-approved, NHBRC enrolled and comes with a written two-year workmanship warranty. We handle City of Cape Town plan submissions on your behalf.
Granny flat rental income in Cape Town: A council-approved NHBRC-enrolled granny flat in Durbanville or Brackenfell generates R6,000 to R10,000 per month. In Bloubergstrand or Table View the same structure earns R8,000 to R14,000 monthly. Return on investment on a compliant build is typically 3 to 5 years. An unapproved structure cannot be legally rented, insured or financed.
What separates our builds: Our quotes start from R85,000 for a single room addition and include council-approved plans, NHBRC enrolment, structural work, electrical COC, plumbing and finishing. Written fixed-price contract before any deposit. Milestone payments — never 100% upfront.
