Costs range from roughly R6,500 to R25,000+ per square metre depending on finish tier, with Gauteng averaging around R13,330-R15,000/m² for a standard build. A typical 150m² standard-tier home in Gauteng lands somewhere between R1.3 million and R2.3 million for the structure alone, before professional fees.

Yes — every new residential home built in South Africa since December 1999 must be enrolled with the NHBRC by law, and the builder must be individually registered too. Non-compliance is a criminal offence carrying a fine of up to R25,000 or up to a year's imprisonment, and the builder also loses the right to claim payment for the work.

Call the NHBRC directly on their toll-free number, 0800 200 824, and ask them to confirm the builder's current registration status. Don't rely on a certificate shown to you alone — registration is renewed annually, and verifying independently is the only reliable check.

The NHBRC's own official guidance is clear: never pay a builder in advance of work being done, only pay once work is completed to your satisfaction. Building loans are structured in stages specifically for this reason. Use our Payment Milestone Checklist for a schedule tied to real, verifiable physical progress.

Straightforward projects typically take 4-12 weeks. If your plans are referred or queried by the municipality, this can stretch to 3 months or even a year — missing documentation is the single biggest cause of delays. Use our Approval Timeline Tracker to see exactly where the time is likely to go for your specific situation.

It depends heavily on your specific numbers — extension pricing per m² is often higher than new-build rates, and second-storey additions can require R40,000-R150,000 in foundation underpinning. Moving involves estate agent commission (5-7.5%+VAT), transfer duty, and bond costs on the new purchase. Use our Extension vs. Move Comparator for a real side-by-side comparison.

NHBRC covers residential home building specifically. CIDB (Construction Industry Development Board) covers commercial and government construction projects. A builder registered with CIDB is not automatically qualified or authorised to build your residential home — confirm NHBRC registration specifically.

A snag list is a written record of all defects and problems you find after moving into your new home. It must be handed to your builder within 90 days of occupation to trigger warranty cover — this window is not flexible, so start compiling your list from day one of occupation.

Generally no — alterations and additions to an existing residential structure are typically excluded from NHBRC enrolment, unlike a genuinely new dwelling. Your builder should still comply with SANS 10400 building regulations regardless, and it's still worth confirming their general NHBRC registration status.

Three tiers: minor defects identified within 3 months of occupation, roof leaks within 1 year, and major structural defects within 5 years — all calculated from your date of occupation, and all contingent on the home having been properly enrolled with the NHBRC before construction began.

Fixed price protects you from cost overruns and gives budget certainty, provided the scope is genuinely well-defined upfront. Cost-plus offers more flexibility for complex renovations where the full scope can't be known in advance, but requires real trust in the specific builder and active oversight of costs as they're incurred.

This is possible in some cases (an "owner builder" may apply for NHBRC exemption), but it removes the professional project management, warranty structure, and accountability a registered builder provides. For anyone without direct construction experience, the savings rarely outweigh the real risk of costly mistakes or delays.

Architect fees run up to 8% of construction value, a structural engineer around 2%, a quantity surveyor up to 4%, and a land surveyor up to 5% if your plot isn't already surveyed. Combined, these can add close to a fifth of your structure cost on top of the builder's own price — a commonly underbudgeted item.

If your builder is NHBRC-registered and your home is properly enrolled, the NHBRC has a formal complaints process and disciplinary powers, including stopping construction and taking action against the builder. This is exactly why verifying registration and enrolment upfront matters — an unregistered arrangement leaves you with far weaker recourse if this happens.

These are commonly excluded from the standard per-m² quote you'll see online, and vary significantly by plot — municipal water, electricity, and sewer connection fees, plus site clearing and access, can add a meaningful amount on top of the structure cost. Ask specifically whether your quote includes these or treats them as separate.

Yes — the structural requirements for supporting an upper floor (stronger foundations, staircases, additional bracing) mean a double-storey build typically costs a real premium per m² over an equivalent single-storey home, even before accounting for any second-storey extension's separate underpinning costs on an existing structure.
