Architects, childcare operators and builders consistently ask the same question early in modular childcare scoping: what does this cost per square metre? The honest answer is that the only useful number is one based on completed comparables, not industry averages.
This guide sets out current cost-per-m² benchmarks for modular childcare construction in Australia, drawn from real EcoPrestige modular supply contracts in 2025-2026. It separates module supply (factory) from builder site scope (civil and install), so each cost line is defensible at the documentation stage.
Module supply cost per m² — Class 9b childcare
Indicative modular supply for Class 9b childcare centres lands at around $2,300/m² (ex GST), fully fitted, delivered to site. That figure includes:
- Structural steel modular shell
- External cladding, windows and doors
- Full bathrooms, change rooms, toilets
- Kitchen joinery and benches (appliances excluded)
- Mechanical units (HVAC)
- LVT flooring throughout
- LED lighting, power and data
- Shop drawings and NCC Class 9b compliance documentation
- Factory QA and delivery
Comparable Class 9b modular childcare projects — actual contract values
Two recent Australian comparables to anchor expectations:
- 956m² ELC, Truganina (VIC) — $2,198,800 ex GST module supply, delivered to site. Effective rate: $2,300/m².
- 807m² ELC, Cranbourne East (VIC) — $1,856,100 ex GST module supply, delivered to site. Effective rate: $2,300/m².
The consistency between sites is the design output of a structural steel modular grid. Once architectural intent locks to module geometry (typical widths 3.45m or 3.48m, lengths up to 13m), the supply price normalises around the benchmark regardless of site.
Builder site scope — what sits outside module supply
Modular supply is only one half of the cost stack. The builder site scope sits with the principal contractor and typically includes:
- RC piers or SHS post bolt-down footings
- Civil works, drainage and stormwater
- Electrical and hydraulic services tie-in
- Module install (crane and connection)
- Acoustic and child-proof fencing
- Soft and hard landscaping
- Permit and compliance handover
For a typical 100-place metro childcare centre, builder site scope lands $1.4-1.8M depending on civil complexity. Sloped sites, sensitive easements and heavy services upgrades push toward the upper end. Flat infill sites with services to boundary sit lower.
All-in D&C cost per m² — modular vs conventional
Adding module supply and builder site scope, all-in D&C for a modular childcare centre typically lands well under conventional construction. Indicative ranges:
- Modular all-in D&C: approximately $3,200-$3,600/m² (ex GST), depending on civil complexity and inclusions
- Conventional all-in D&C: approximately $3,800-$4,500/m² (ex GST) for comparable Class 9b spec, based on current Australian builder pricing
The cost gap is not the headline. The programme gap usually carries more commercial weight: permit-to-OC of approximately 7 months for the modular path, against 12-14 months for conventional Class 9b construction. For operators with enrolment schedules and lease commencement dates locked to a specific term, the programme certainty is often what makes modular the answer.
Where modular childcare cost-per-m² breaks down
The benchmark above holds for centres that work with a structural steel modular grid. It breaks down — meaning the cost normalisation goes away — when:
- Architectural intent forces non-rectangular module geometry without considering splice penalties
- Internal ceiling heights above 2.7m are used throughout (drives external module height above 3.2m, breaking standard ocean container shipping economics)
- External finishes shift away from cladded steel modular envelopes (e.g. full masonry external walls, which defeats the modular premise)
- The site has access constraints that prevent crane sets within a single working day per module group
Each of these can be designed around. The earlier in documentation the modular grid is considered, the smaller the cost penalty.
How to use these benchmarks
For architects working on a current childcare project, the cost-per-m² benchmark is most useful at town planning and early documentation stage. That is the window where module geometry can still be reflected in the architectural setout without redesign cost.
For builders and developers preparing a feasibility, use $2,300/m² (ex GST) as your supply line, plus $1.4-1.8M as your builder site scope, plus 12-15% margin and contingency. That stack lands within 5% of formal modular tender pricing on most metro centres.
For childcare operators, the benchmark to test against is the combined permit-to-OC programme of approximately 7 months. If your conventional procurement pathway is sitting at 12 months or longer with timing risk, the modular pathway is worth pricing formally.
What changes the number
Three factors move modular childcare cost-per-m² off the $2,300 benchmark in either direction:
- Compliance class. Class 9b applies to most childcare. Class 5 office variants for staff-only spaces drop the spec slightly. Specific approvals (e.g. NQF outdoor space ratios) do not change the modular spec but can change the building footprint required.
- Internal ceiling height. Default 2.7m internal sits at $2,300/m². Stepping down to 2.5m internal ceiling (still above NCC Class 9b minimum of 2.4m) drops module external height to 2.9m, which fits standard 40ft HQ extended ocean containers. The freight saving is meaningful — approximately $80,000 across 8 modules — flowing through to a reduced supply price of around $2,150-$2,200/m².
- Site exposure. Coastal childcare sites move to upgraded cladding, fastener schedule and corrosion-class hardware. Adds approximately $150-$250/m² to module supply on aggressive coastal exposure (C4-C5).
Reference projects and supporting evidence
The benchmarks above are based on completed and active Class 9b modular childcare scopes delivered through the EcoPrestige supply layer. Specific project references including drawings, scope of works, NCC Class 9b compliance documentation and factory QA protocols are available to qualified architects, builders and developers under NDA.

Frequently asked questions
What is a realistic modular childcare cost per square metre in Australia in 2026?
For Class 9b modular childcare module supply (fully fitted, delivered to site), $2,300/m² ex GST is the working benchmark based on 2025-2026 contracts. All-in D&C with builder site scope sits approximately $3,200-$3,600/m² depending on civil complexity.
How does modular childcare cost compare with conventional construction?
All-in modular D&C lands $200-$1,300/m² below comparable conventional childcare construction. The headline saving is meaningful but the programme saving — permit-to-OC of approximately 7 months versus 12-14 months conventional — usually carries more commercial weight for operators on enrolment timing.
Does $2,300/m² include the builder?
No. $2,300/m² covers module supply only — factory build, fit-out, delivered to site. Builder site scope (civil, footings, services tie-in, install, fencing, landscaping) is separate and adds approximately $1.4-1.8M for a typical 100-place metro centre.
What does the modular delivery programme look like for a Class 9b centre?
From confirmed final design and procurement: factory production approximately 8-10 weeks, delivery and install approximately 1-2 weeks, on-site builder works approximately 8-10 weeks running in parallel. Permit-to-OC overall lands at approximately 7 months for an established modular pathway. Conventional comparable typically 12-14 months.
Are EcoPrestige modules NCC Class 9b compliant?
Yes. Modules are supplied with full NCC Class 9b compliance documentation including structural, acoustic, thermal and fire engineering, evidence of suitability acceptable to Australian building surveyors, and factory QA records.
