Based on Setout’s estimate model, building an office building in East London costs roughly R 8 774–R 19 680 per m², with a typical rate around R 12 300 per m². Here’s how that breaks down, and how we calculated it.
A worked example
A 800 m² office building at the typical R 12 300/m² works out to about R 9 840 000 for construction. Of that, labour is roughly 27% (~R 2 656 800); materials and plant make up the rest.
Building in East London
East London sits in the Eastern Cape, mid-tier on published provincial cost estimates. On the Indian Ocean at the mouth of the Buffalo River, it shares the coastal-durability considerations of the region — corrosion-resistant specification for exposed metalwork is a sensible default. Its economy is anchored by the East London Industrial Development Zone — South Africa's first operational IDZ — and a major Mercedes-Benz assembly plant beside the harbour, which sustain automotive and industrial construction demand. That industrial base and port access support material logistics for larger commercial and industrial projects in the city.
What drives the cost of an office building
Office cost is driven by services and specification rather than structure. Air-conditioning, IT and data cabling, lighting, ceilings, and the fit-out (partitioning, joinery, finishes) make up a large share of the rate, and a prestige-grade office runs well above a basic one. Parking — structured or basement — is a major separate cost. Whether the number is for shell-and-core or a full fit-out matters enormously: a developer's shell rate and a tenant's completed office are very different figures, so it's important to know which is being quoted.
What the low, typical and high rates buy
Low: R 8 774/m² in East London, about R 7 019 200 for 800 m²
A low-rise building in a business park: simple frame, standard curtain or punched windows, basic air-conditioning, and a shell-and-core delivery that leaves fit-out to the tenant.
Typical: R 12 300/m² in East London, about R 9 840 000 for 800 m²
A two- to five-storey office with a central core, full air-conditioning, raised access floors or ceiling services, a reasonable façade and a green-building target, delivered with a standard tenant installation.
High: R 19 680/m² in East London, about R 15 744 000 for 800 m²
A prestige or high-rise office: high-performance glazed façade, premium lobby and lift installation, generous floor-to-floor heights, full backup power, and a fitted specification that suits a corporate head office.
Budget by floor area in East London
Construction cost only, at East London’s low, typical and high rates for an office building. Multiply your own floor area by the rate per m² for a figure in between.
| Floor area | Low | Typical | High |
|---|---|---|---|
| 400 m² | R 3 509 600 | R 4 920 000 | R 7 872 000 |
| 800 m² | R 7 019 200 | R 9 840 000 | R 15 744 000 |
| 2000 m² | R 17 548 000 | R 24 600 000 | R 39 360 000 |
How East London compares with other cities
At a typical R 12 300/m², East London is level with the median of the twelve cities in this model for an office building. 5 cities are dearer and 4 are cheaper. The range runs from R 9 150/m² in Rustenburg to R 16 950/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 East London
Building plans for an office building in East London go to the Buffalo City 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. Larger non-residential buildings will also need a fire-protection plan approved by the municipal fire department.
Costs on top of the building rate
The rates above stop at the building. For an office building, the items that most often get left out of an early budget are:
- Tenant fit-out: partitions, ceilings, joinery, furniture and IT
- Structured or basement parking
- Green Star certification fees and the design work behind them
- Generators, UPS and water storage if not in the base building
- Bulk contributions and electrical supply capacity
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 Office building (Gauteng-anchored, excl. VAT, professional fees and site works) adjusted by the Eastern Cape provincial factor (×0.82), 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 an office building in East London?
- Based on Setout's estimate model, roughly R 8 774–R 19 680 per m² (typical R 12 300). For a 800 m² office building, that's around R 9 840 000 for construction — excluding land, professional fees, VAT and municipal costs.
- Does an office cost include the fit-out?
- It depends what's being priced. A shell-and-core rate covers the structure, envelope, and base services; the tenant then pays for the fit-out — partitions, ceilings, finishes, workstations. A fully-fitted office rate is much higher. Always confirm which one a figure refers to.
- Why is building in East London priced this way?
- East London is in Eastern Cape. 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 Office building (Gauteng-anchored, excl. VAT, professional fees and site works) adjusted by the Eastern Cape provincial factor (×0.82), 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.
