What's the biggest cost in a typical warehouse fitout?

Racking is usually the largest single line item, but its actual cost depends heavily on storage density needs and racking type, not a flat rate, so it isn't meaningful to quote one figure across different operations.

Is installation labour a small add-on to the racking cost?

Not necessarily. A complex site with a poor slab, tight column spacing or difficult access can add real cost to installation independent of what the racking components themselves cost.

Should lighting be planned before or after the racking layout?

Before, ideally, alongside it. Retrofitting lighting after racking is installed is more disruptive and usually more expensive than designing both together from the start.

Does office space inside a warehouse really affect fitout cost meaningfully?

Yes, indirectly. Every square metre used for office or amenity space is a square metre not available for racking, so it's a genuine trade-off against storage capacity, not just a fixed add-on cost.

What Actually Drives the Cost of a Warehouse Fitout

An empty shed is a shell, not a working warehouse. Getting from one to the other means racking, lighting, installation labour, line marking, dock equipment and usually some office space, and each of those items is driven by different things. This page covers the cost structure, not a dollar figure, because what drives your fitout cost is specific to your building and your operation.

Racking is the largest line item, and it isn't one number

Racking cost scales with how much storage you need and what type suits your stock, not a flat rate per square metre of floor. Selective racking is generally the cheapest per pallet position because it's the simplest structure, while denser systems like drive-in or pallet flow racking cost more per position but pack more pallets into the same footprint, which can make them cheaper overall for the right stock profile even at a higher unit cost.

Getting an accurate figure for your own site means working from what installation for your specific configuration actually costs rather than a generic per-square-metre estimate, because bay height, beam levels, brand and site access all move the number independently of each other.

Installation labour is separate from the steel

The racking components themselves are one cost; getting a crew to set out the layout, anchor frames into the slab and check everything for plumb is another, and the two don't scale together in a simple way. A straightforward, regular-grid installation on a good slab costs less per bay than a complex layout with obstructions, tight column spacing, or a floor that needs remediation before anchors can go in properly.

What a proper installation actually includes, setting out, bolt-down, and a handover with load signs for every configuration, is worth understanding before assuming installation is a rounding error on top of the racking price.

Lighting and line marking

Lighting needs to suit both the racking layout and the work happening in each zone, picking, staging, office space, and retrofitting it after racking goes in is more disruptive and often more expensive than planning it alongside the layout from the start.

Aisle and walkway marking usually follows the same setting-out data used for the racking layout itself, marking aisles, pedestrian routes and staging areas, and it's cheaper to do once, properly, at fitout than to redo after the fact when someone notices the marked routes don't match how the space is actually being used.

Dock equipment and offices

Dock levellers, bumpers, and any automated dock doors are a separate cost category tied to how much truck traffic the site actually handles, not to the racking or floor space at all. A site running frequent truck movements justifies more dock investment than one taking a handful of deliveries a week, and dock and staging area design decided early avoids retrofitting equipment around trucks that are already queuing.

Office space, whatever mezzanine or ground-floor area is needed for admin, despatch and amenities, competes with storage footprint directly. Every square metre given to an office is a square metre not holding racking, which is worth weighing against how much office space the operation genuinely needs versus what feels standard.

What actually drives the total

Four things move a fitout cost more than any single line item: how much storage density you need, which drives racking type and count, how complex the site itself is, slab condition, column grid, access for the install crew, how much of the fitout can use standard components versus custom work, and how tight the timeline is, since compressed schedules generally cost more than ones with reasonable lead time built in.

None of that reduces to a single average figure worth quoting, because two warehouses of the same floor area can have genuinely different fitout costs depending on all four of those factors. What's useful is understanding the structure, so a quote can be checked against it rather than taken at face value.
