How Much Does it Cost to Build A Bulk Storage Building?

Written by Almanzo Boakes | Oct 12, 2025 10:32:00 PM

One of the key questions you might be asking is, “How much will a bulk storage facility cost to build?”

As with most commercial builds, the answer depends on several variables, including size, site conditions, materials, location, and the specific requirements of your operation.

This guide is designed to give you clarity. Whether you’re in the early planning stages or want to better understand the drivers behind cost fluctuations, we’ll break down the key factors that influence the final price of your bulk store.

What is the average cost for the bulk store superstructure?

The base build of a bulk store typically ranges from $500 to $800 per m², depending on size, height, and specification. This includes the steel structure, roof, wall cladding, concrete floor, and foundations, but excludes earthworks, offices, hardstand areas, and specialised systems.

Key factors that influence cost

Size and Span

Larger buildings (over 2,000 m²) generally have a lower cost per m² because fixed costs are spread over more area.
Clearances typically range from 9–11m in bulk stores, with higher structures incurring higher costs.

Load-Bearing Concrete Walls

For most bulk storage applications, load-bearing precast concrete walls are essential to contain product.

Costs typically sit between $400 and $600 per m² of wall face, depending on wall height, reinforcement requirements, and the weight of the stored material. Taller walls or heavier products require more reinforcing, which increases cost.

Site Conditions

Pricing assumes a level site with good ground conditions. Poor ground, grading, or rock removal can quickly increase costs. In some cases, engineered solutions like piling or gravel raft foundations may be required.

Office Space Costs: Shell and Fit-Out

How much does an office in a bulk store cost?

While many bulk storage facilities have minimal office requirements, a small office or control room is still common, often prefabricated or basic in design.

Typical cost range: $2,700–$3,500 per m² for design, build, and all trades (including electrical and plumbing). This price includes the shell, basic fit-out, and services.

Factors that can affect office costs include:

The quality of finishes and fit-out level (from simple vinyl floors to tiled bathrooms).
Number of bathrooms or amenities for staff.
External cladding and glazing choices.
Whether the office is single-level or mezzanine.

Exterior Works AND Hardstand Areas

How much should I budget for the yard and access areas?

Yards and traffic areas are critical in bulk stores, as product movement often involves heavy vehicles, loaders, and trucks. The surface type and load requirements will drive the cost.

Gravel yard (standard traffic): $70–$100 per m²

Heavy-duty concrete yard: $110–$180 per m² (depending on subbase preparation and reinforcement)

Additional exterior work costs can include:

Kerbing, drainage, and line marking (often $20–$50 per m² on top of concrete pricing)

Stormwater management – basic systems can be $10–$20 per m², but sites with soakage issues or environmental compliance needs may require more expensive treatment.

Site access/crossings – new crossings typically cost $20–$50k each.

Specialised Systems and Power Supply Works

Bulk stores that incorporate blending plants or other high-power equipment may require significant electrical upgrades.

Additional transformers and network upgrades can cost anywhere from $100,000 to $500,000, depending on your network provider’s fee structure and the complexity of the installation.

Facilities used purely for storage generally have lower power demands.

Summary: Bulk Store Cost Ranges

Component	Typical Range (excl. GST)
Bulk store base build	$500–$800 per m²
Load-bearing concrete walls	$400–$600 per m² wall face
Office (shell + fit-out)	$2,700–$3,500 per m²
Gravel yard	$70–$100 per m²
Heavy-duty concrete yard	$110–$180 per m²
Power upgrades (if required)	$100k–$500k lump sum
