The short answer
In 2026, a standard steel-portal warehouse in Durban costs about R5,800 to R11,600 per m² to build, excluding VAT. Offices and ablutions inside it cost about R10,500 to R13,900 per m², and a low-rise office building about R11,300 to R14,400 per m². These rates cover the building only. Land, site works, bulk services, professional fees and 15% VAT come on top.

Durban’s industrial market is busy. In the first half of 2026, eThekwini Municipality approved building plans worth R3.97 billion, and approved industrial and warehousing floor space more than tripled, from 24,497 m² to 83,708 m² (Inside Metros, September 2026). If you are planning a warehouse, distribution centre, workshop, office or retail building in Durban, Cornubia, Riverhorse Valley, Dube TradePort or along the North Coast, this guide sets out what it costs to build in 2026, what the headline rates leave out and what moves the price.
JehCon Group is a registered building contractor based in Ballito. Our commercial and industrial work includes the R9m SolAqua Holdings warehouse, the R40m StoneRidge office for MWLF Architects, McDonald’s restaurants and the R250m Bryanston Shopping Centre revamp for Redefine, and our founder has delivered projects worth up to R180 million.
Commercial and Warehouse Build Costs per m² in 2026
These are JehCon Group’s own 2026 rates for commercial and warehouse buildings in Durban, excluding VAT.
| Building type | 2026 guide (R/m²) |
|---|---|
| Warehouse, light-duty (steel frame, steel cladding and roof sheeting) | R5,800 – R7,700 |
| Warehouse, heavy-duty (steel frame, brickwork to ceiling, cladding above) | R6,500 – R11,600 |
| Admin offices, ablutions and change rooms | R10,500 – R13,900 |
| Cold storage facility | R19,600 – R28,900 |
| Low-rise office park, standard specification | R11,300 – R14,400 |
| Low-rise office park, prestige specification | R14,600 – R22,500 |
| Local convenience retail centre (up to 5,000 m²) | R11,100 – R15,100 |
| Parking on grade, including landscaping | R800 – R1,000 |
All rates exclude VAT, site infrastructure, professional fees, future escalation and finance costs. Costs depend on the site, the specification and the tenant’s requirements, so treat these as planning figures.
Worked Example: A 2,000 m² Warehouse in Durban
Here is a typical 2026 planning budget for a heavy-duty warehouse with brickwork to ceiling height, steel cladding above and an internal office and ablution block, priced at the middle of the 2026 range.
| Warehouse floor, 1,800 m² @ R9,050 | R16,290,000 |
| Offices & ablutions, 200 m² @ R12,200 | R2,440,000 |
| Building cost, excluding VAT | R18,730,000 |
| VAT at 15% | R2,809,500 |
| Building cost, including VAT | R21,539,500 |
That works out to about R9,400 per m² for the building excluding VAT. The site-specific items below then need adding, which is why we always build a project budget from a Bill of Quantities rather than a single rate.
What the Cost per m² Leaves Out
Most budget overruns on commercial projects come from items that were never in the headline rate. Allow for these separately:
- Site platform and earthworks: cut and fill, compaction, retaining walls and slope stabilisation, which add up quickly on Durban’s hilly and clay sites
- External works: truck yards, heavy-duty paving, parking, stormwater attenuation, fencing, gatehouses and guardhouses
- Bulk services: municipal contributions, a new electrical supply or mini-substation, water and sewer connections
- Fire protection: sprinklers, hydrants and hose reels where storage height, area or stock type requires them under SANS 10400-T, plus a fire engineer’s rational design
- Operational equipment: dock levellers, roller shutter doors, racking, cold rooms, mezzanines and specialist floor finishes
- Professional fees: architect, structural and civil engineers, quantity surveyor, fire engineer, land surveyor and geotechnical investigation
- Escalation, finance and VAT: price increases during the build, interest on development finance, and 15% VAT
What Moves the Price of a Warehouse
Floor slab and racking loads
The floor is often the single biggest decision. A slab designed for forklifts, point loads from high racking or very narrow aisle trucks needs more thickness, reinforcement and flatness control than a light-storage floor. Agree your racking layout and loads before the engineer designs the slab, not after.
Clear height and roof span
Taller eaves and wider clear spans need heavier steel portals and more cladding. Extra height can still be the cheapest way to add storage capacity, so test a few options with your racking supplier.
Coastal specification
Near the coast, from the Bluff and Prospecton to Cornubia and Ballito, salt air attacks steel, fixings and roof sheeting. Corrosion-protected steel, coastal-grade roof sheeting and stainless or galvanised fixings cost more up front but avoid early replacement.
Building shape and offices
A square plan needs less external wall per m² of floor than a long, narrow one, so it costs less to enclose. Offices, ablutions and change rooms cost about 50% more per m² than the warehouse floor, so size them to what the operation actually needs.
Market conditions in 2026
The FNB/BER Building Confidence Index fell to 38 in the second quarter of 2026, and builders reported that input costs jumped sharply between the first and second quarters (TimesLIVE, June 2026). Lock in steel and roof sheeting prices early, and agree up front how escalation will be handled in the contract.
Building at Dube TradePort, Cornubia and Other Durban Nodes
Where you build changes the approvals, the site costs and sometimes the specification.
- Dube TradePort (La Mercy): a Special Economic Zone next to King Shaka International Airport. The SEZ provides serviced, zoned land in TradeZone 1 and TradeZone 2, and private developers and occupiers lease the land and build their own facilities. Expect zone-specific design and development rules on top of the National Building Regulations.
- Cornubia and the northern corridor: demand for mid-size units and 2,000 m²+ warehouses close to the N2 and the airport. Sites are often on platforms cut into slopes, so check the earthworks and retaining allowances.
- Riverhorse Valley, Springfield and the South Durban basin: established nodes close to the city and the port, where infill sites, existing services and tight access shape the programme.
- Ballito and the KwaDukuza area: smaller business parks and light industrial units under KwaDukuza Municipality rather than eThekwini.
Approvals: eThekwini and the National Building Regulations
Every new commercial or industrial building in Durban needs approved plans from eThekwini Municipality before work starts, under the National Building Regulations and SANS 10400. A commercial submission normally includes architectural drawings, the SANS 10400-A forms appointing the competent persons, structural and civil engineering designs, a fire protection plan or rational fire design under SANS 10400-T, and energy-efficiency compliance under SANS 10400-XA. Buildings older than 60 years also need a heritage permit from Amafa before alterations. We coordinate with your professional team so the building is built strictly to the approved drawings and inspections are passed along the way.
How Long Does a Warehouse Take to Build?
As a guide, allow 2 to 4 months for design, geotechnical investigation and municipal approvals, then about 5 to 8 months on site for a straightforward 1,000 to 3,000 m² steel-portal warehouse. Large earthworks, cold storage, heavy fire engineering or a big office component add time. A clear programme agreed at tender stage, with steel and roof sheeting ordered early, keeps the occupation date realistic.
How JehCon Prices a Commercial Build
A rate per m² is the right tool for a feasibility study. Before you sign a building contract, you need a price built from your own drawings. On every commercial and industrial project we:
- Prepare a detailed Bill of Quantities with our in-house quantity surveyors, so every item is measured and priced
- Value-engineer early, testing steel, slab, cladding and layout options against your budget before the design is fixed
- Agree a programme around your occupation date, tenant lease or trading requirements
- Contract under JBCC, with clear terms for variations and escalation
- Report on cost and progress to owners, tenants and the professional team throughout
