Based on Setout’s estimate model, building a flat / apartment in Durban costs roughly R 10 878–R 24 420 per m², with a typical rate around R 14 985 per m². Here’s how that breaks down, and how we calculated it.
A worked example
A 75 m² flat / apartment at the typical R 14 985/m² works out to about R 1 123 875 for construction. Of that, labour is roughly 27% (~R 303 446); materials and plant make up the rest.
Building in Durban
Durban is in KwaZulu-Natal, which tops published industry cost estimates among the provinces — so builds here sit at the upper end of the national range. The signature local driver is the coastal marine environment: high subtropical humidity and salt-laden air accelerate corrosion of metal fixtures, fixings, and reinforcement, so coastal sites commonly carry corrosion-resistant specifications and more robust roofing against wind and weather. Durban is also home to the busiest port in sub-Saharan Africa, which shapes local material availability and import logistics. Specifying for durability against the coast is a genuine, recurring add-on here rather than an optional upgrade.
What drives the cost of a flat / apartment
Flats and apartments carry the cost of going vertical. Multi-storey structure, lifts, fire escapes and fire-rated construction, and more demanding services (water pressure, drainage stacks, electrical distribution) all lift the rate above a single house. Basement or structured parking is one of the biggest line items and is often priced separately per bay. Set against this, units are compact and repetitive, which helps — but the structural and compliance overhead means apartments rarely reach the low rates of simple residential work.
What the low, typical and high rates buy
Low: R 10 878/m² in Durban, about R 815 850 for 75 m²
A walk-up block of three or four storeys with no lift, a simple concrete frame or load-bearing masonry, compact units, standard finishes and open surface parking.
Typical: R 14 985/m² in Durban, about R 1 123 875 for 75 m²
A mid-rise block with lifts, a concrete frame, fire-rated stair cores, better finishes in units and common areas, and some covered or structured parking.
High: R 24 420/m² in Durban, about R 1 831 500 for 75 m²
A prestige block: high-rise structure, basement parking over several levels, high-specification units with premium kitchens and bathrooms, concierge and amenity floors, and heavier building services including backup power and water.
Budget by floor area in Durban
Construction cost only, at Durban’s low, typical and high rates for a flat / apartment. Multiply your own floor area by the rate per m² for a figure in between.
| Floor area | Low | Typical | High |
|---|---|---|---|
| 50 m² | R 543 900 | R 749 250 | R 1 221 000 |
| 75 m² | R 815 850 | R 1 123 875 | R 1 831 500 |
| 110 m² | R 1 196 580 | R 1 648 350 | R 2 686 200 |
How Durban compares with other cities
At a typical R 14 985/m², Durban is 35% above the median of the twelve cities in this model for a flat / apartment. 1 city is dearer and 10 are cheaper. The range runs from R 8 235/m² in Rustenburg to R 15 255/m² in Cape Town. The model sets rates by province, so cities in the same province carry the same figure; the local factors described above are what separate them on a real project.

Plans and approvals in Durban
Building plans for a flat / apartment in Durban go to the eThekwini Metropolitan Municipality for approval under the National Building Regulations and Building Standards Act 103 of 1977, with SANS 10400 as the technical standard. Work may not start before the plans are approved. The municipality also checks the proposal against its land use scheme; if the design needs a rezoning, a consent use or a building-line relaxation, add that process to the programme before you add it to the budget. A new home must also be enrolled with the NHBRC before construction begins, and the builder must be registered with the NHBRC.
Costs on top of the building rate
The rates above stop at the building. For a flat / apartment, the items that most often get left out of an early budget are:
- Basement or structured parking, often priced per bay as a separate item
- Fire engineering, sprinklers and the fire-plan approval
- Bulk-services contributions, which scale with the number of units
- NHBRC enrolment of each unit and sectional-title registration
- Lifts maintenance contracts and the first years of operating cost
VAT at 15% applies to the building contract and to professional fees from VAT-registered consultants.
How we calculated this
AECOM 2025/26 base rate for Flat / apartment (Gauteng-anchored, excl. VAT, professional fees and site works) adjusted by the KwaZulu-Natal provincial factor (×1.11), derived from ooba's provincial build-cost table with Gauteng set to 1.0. Figures are planning-stage estimates, not a quote or a survey. Labour assumed at 27% of total (typical 25–30%). Excludes land, professional fees, VAT, and municipal contributions.

Questions
- How much does it cost to build a flat / apartment in Durban?
- Based on Setout's estimate model, roughly R 10 878–R 24 420 per m² (typical R 14 985). For a 75 m² flat / apartment, that's around R 1 123 875 for construction — excluding land, professional fees, VAT and municipal costs.
- Why do flats cost more per m² than houses?
- Going vertical adds cost: multi-storey structure, lifts, fire-rated construction and escapes, and heavier services (drainage stacks, water pressure, electrical distribution). Structured or basement parking is a major separate cost. Repetition helps, but the compliance and structural overhead keeps the rate up.
- Why is building in Durban priced this way?
- Durban is in KwaZulu-Natal. Our model applies a provincial cost factor to a national base rate to reflect local labour rates, material transport, and market demand. AECOM 2025/26 base rate for Flat / apartment (Gauteng-anchored, excl. VAT, professional fees and site works) adjusted by the KwaZulu-Natal provincial factor (×1.11), derived from ooba's provincial build-cost table with Gauteng set to 1.0. Figures are planning-stage estimates, not a quote or a survey. Labour assumed at 27% of total (typical 25–30%). Excludes land, professional fees, VAT, and municipal contributions.
- What is not included in this estimate?
- The rate covers building work and materials only. It excludes the land, professional fees (architect, engineer, quantity surveyor), municipal connection and contribution charges, VAT, and any abnormal site or foundation costs. For a tender-ready figure, price the actual Bill of Quantities.
