Prices are indicative and exclude VAT, site clearing, geotechnical surprises, transport distance, and any civil works not included in the agreed scope. Final pricing depends on your location, height, access openings, cladding choice, foundations, and finishes.

What affects the final quote

  • Foundations and slab: poor soil, deeper footings, or slab design can change the budget quickly.
  • Height and door openings: taller eaves and larger roller doors increase steel tonnage and cladding requirements.
  • Location and transport: delivery distance, cranage, and access conditions influence installation costs.
  • Fit-out scope: insulation, partitions, electrical work, and office areas push the build toward turnkey pricing.

Cost per square metre

  • Structure only: R1 050 to R1 300 per m²
  • With cladding: R1 350 to R1 500 per m²
  • Turnkey build: R1 650 to R2 700 per m²

These ranges help you benchmark value across different warehouse footprints, but the best comparison is still a quote built around your site, access needs, and specification level.
