Factory Construction Sydney & NSW

State Property Development undertakes factory construction, extensions, and alterations across Greater Sydney. NSW Builders Licence 355555C. $20M public liability. Factory construction differs from standard commercial or warehouse building in one key respect – the building has to be designed around a manufacturing or production process, not the other way around. Floor loading, services infrastructure, ventilation, and fire separation all depend on what’s actually happening inside the building.

Most of our factory work is extensions and alterations to operating facilities rather than greenfield new builds – which means staged construction sequencing to keep production running is usually the central planning challenge, not just the construction itself.

What We Build

• New factory construction – steel portal frame and tilt-slab
• Factory extensions – adding floor area to existing production facilities
• Factory alterations – reconfiguring layout for new equipment or processes
• Structural upgrades for new equipment loads
• Services extension – three-phase power, compressed air, process water, extraction
• Amenities and office component construction within factory sites
• Loading dock and yard construction for materials and freight handling

Factory Construction Costs – Sydney 2026

• New factory shell (steel portal or tilt-slab): $1,000-$2,200/sqm depending on structural and services requirements
• Factory extension to existing facility: $600-$1,400/sqm depending on services integration complexity
• Factory alteration (reconfiguration, no new floor area): $250-$700/sqm depending on scope

Factory costs vary more than warehouse costs because the services and structural requirements are process-specific. A factory housing light assembly work costs significantly less to build than one requiring heavy floor loading, specialised ventilation, or process water infrastructure. We price based on your actual equipment and process requirements, not a generic per-sqm assumption.

Building Classification and Compliance

Factories are typically classified under NCC Class 8 – buildings used for production, assembly, altering, repairing, packing, finishing, or cleaning of goods. This classification carries specific requirements for fire resistance, smoke hazard management, and in some cases explosion or hazardous materials provisions depending on what’s manufactured or stored on site. We work through classification requirements with your building designer and, where relevant, a fire engineer before construction documentation is finalised.

Factory sites sit within the same industrial zoning framework as warehouses (IN1, IN2, IN3 under most Sydney LEPs), though heavier manufacturing processes may be restricted to IN3 (Heavy Industrial) zones specifically. We confirm zoning permissibility for your intended use before pricing.

Extending or Altering an Operating Factory

Extensions and alterations to a factory that’s still running production require a construction sequence built around your operational needs, not just the building program. We plan work zones, temporary services, and noise/dust management to minimise disruption, and schedule the most disruptive work – structural connections, services tie-ins – for planned downtime windows where possible.
