Industrial Warehouse Construction: Cost Per Square Metre in 2026

Warehouse construction has its own commercial logic — high volume, low finishes, fast programme. Get the structural and envelope basics right and a 10,000 m² shed can be delivered in 26 weeks. Get them wrong and you're paying for steel that doesn't span what it should.

The headline numbers

UK warehouse shell-and-core costs in 2026 (excluding land, professional fees, service-road agreement highways, and tenant fit-out):

• Sub-2,000 m² distribution unit, 8 m eaves: R13,000 – R17,000 per m²
• 5,000 – 15,000 m² mid-box, 10–12 m eaves: R11,000 – R14,500 per m²
• 15,000 – 40,000 m² big box, 15 m eaves: R10,000 – R13,000 per m²
• 40,000+ m² mega-distribution, 18+ m eaves: R9,600 – R12,500 per m²
• Cold storage adder: +R5,000 – R9,000 per m²
• Cross-dock configuration adder: +R800 – R1,600 per m²

Office content (typically 5–15% of footprint at R30,000 – R50,000 per m²) is the single biggest swing factor. A 10,000 m² shed with a 1,000 m² office costs significantly more per m² than the same shed with a 200 m² office.

Structural cost drivers

Eaves height

Every additional metre of eaves height adds roughly 2–4% to frame cost. Modern logistics tenants want 12–15 m clear internal heights for automated racking. Building to 10 m saves money but commits the asset to a smaller pool of tenants.

Bay sizing

Standard column grids are 24 × 12 m or 30 × 12 m. Wider grids reduce internal columns (good for racking flexibility) but increase steel tonnage. Modern build-to-suit logistics often specifies 50+ m clear spans to one side for cross-dock operations — these cost a premium.

Floor slab loading

• 50 kN/m² UDL — standard distribution
• 100 kN/m² UDL — heavy storage, automated racking
• Wheel loads up to 7.5 tonnes — VNA forklift operations

Slab cost ranges from R900 – R1,700 per m². Specifying higher loading than the use requires is one of the most common money-burners on warehouse builds.

Envelope

Standard envelope spec for South African warehouses:

• Built-up insulated cladding: 80–120 mm composite panel, achieving U-value of 0.25–0.35 W/m²K
• Rooflights: 12–15% of roof area for daylight
• Loading docks: typically one per 1,000 m² for distribution use
• Level access doors: one per 4,000–6,000 m² for HGV side-loading

Sustainability and Agrément South Africa / CSIREAM

Agrément South Africa / CSIREAM Excellent is now the baseline expectation for institutional-grade South African logistics. Agrément South Africa / CSIREAM Outstanding adds 4–7% to cost but improves long-term lease value. Key levers:

• EPC A rating (SANS 10400-XA top tier) envelope specification
• Roof-mounted solar PV (capex ~R11,000–R14,000 per kWp)
• Air-source heat pumps for office space
• Rainwater harvesting for HGV wash and toilet flushing
• EV charging infrastructure for car parks

Programme

Indicative durations:

• 2,000 m² unit: 18–22 weeks shell-and-core
• 10,000 m² unit: 26–32 weeks
• 40,000 m² unit: 36–46 weeks

Slab pour, steel erection, and cladding are the critical path. Foundation strategy (raft vs piles vs ground beams) has the biggest impact on programme — choose early.

Common cost pitfalls

• Designing for ambiguous occupier loading. Without a tenant brief, designs default to conservative figures that add 8–12% to steel.
• Under-investing in the slab. A bad slab is the single most expensive thing to fix retrospectively.
• Ignoring HGV swept paths early. Late changes to dock layout reshape the entire structural grid.
• Skimping on rooflights to chase Agrément South Africa / CSIREAM credits. Operators value daylight; tenants will negotiate the credit back.

service-road agreement and planning costs

Highway works under service road agreement of the National Road Traffic Act / SANRAL processes regularly add R4,000,000 – R30m to a logistics scheme, depending on site. Drainage attenuation, Development contributions (under SPLUMA) contributions, and biodiversity net gain (EIA / NEMA) requirements have all increased significantly since 2024. Build them into the appraisal early.
