Breaking Down Project Costs

A complete LMR development project involves more than construction. Here’s how costs typically break down:

For a 3-Townhouse Development

Cost Category	Typical Range	% of Total
Land Acquisition	$1,200,000-2,500,000	40-50%
Construction (3 × 150m²)	$1,260,000-1,440,000	30-35%
Site Works	$150,000-250,000	5-7%
Approvals & Fees	$80,000-120,000	2-3%
Professional Fees	$100,000-150,000	3-4%
Finance Costs	$150,000-250,000	4-6%
Contingency	$100,000-150,000	3-4%
Total Project	$3,040,000-4,860,000	100%

Cost Per Component Explained

Land Acquisition: LMR eligible land (within 800m of stations) commands premium prices. Inner ring suburbs like Burwood or Strathfield may exceed $2.5M for suitable lots, while Western Sydney locations like Penrith offer better value.

Construction: The modular building cost including factory manufacturing, transport, and installation. This is typically the most predictable cost component.

Site Works: Includes demolition of existing structures, site preparation, foundation construction, and service connections. Costs vary significantly with site conditions. Sloping sites or poor soil conditions increase costs.

Approvals & Fees: CDC application fees, council contributions (Section 7.11/7.12), BASIX certification, and development contributions.

Professional Fees: Surveyor, structural engineer, certifier, and project management fees.

Finance Costs: Interest and fees on construction finance. Modular’s shorter timeline reduces this significantly compared to traditional construction.

Contingency: Standard 5 to 10% allowance for unexpected costs. Well planned modular projects typically use less contingency than traditional builds.

What Affects Modular Construction Costs

Site Factors

Location: Transport distance from factory affects delivery costs. Remote sites add logistics complexity.

Access: Restricted access requiring smaller transport vehicles or specialised equipment increases costs. Crane requirements also vary by site.

Site Conditions: Slope, soil type, and existing structures affect foundation and site preparation costs. Flat, clear sites are most economical.

Services: Distance to water, sewer, and electrical connections affects service provision costs.

Design Factors

Size: Larger projects benefit from economies of scale. Cost per m² typically decreases as project size increases.

Complexity: Simple rectangular forms are most efficient. Complex shapes, multiple levels, and architectural features add cost.

Repetition: Multiple identical units (like townhouse developments) achieve better factory efficiency than unique designs.

Specification Level: Internal finishes represent 15-25% of construction costs. Specification choices significantly impact total price.

Market Factors

Factory Capacity: High demand periods may affect pricing and availability. Planning ahead secures better scheduling.

Material Costs: Global supply chain conditions affect material pricing. Fixed price contracts protect against increases after signing.

Labour Market: Skills shortages affect on site completion costs more than factory manufacturing, which uses permanent workforce.

Modular vs Traditional: Cost Comparison

Raw Construction Costs

Traditional and modular construction have similar per square metre rates. The difference lies in total project economics:

Factor	Traditional	Modular	Difference
Base Construction	$2,800/m²	$3,000/m²	+7%
Weather Delays	5-15% overrun	Minimal	-10% average
Variations	10-20% typical	Fixed price	-15% average
Rework	3-7%	Under 1%	-4% average
Net Construction	+15-30% over budget	Within 5%	Modular wins

Total Project Economics

Timeline Impact:

Traditional (24 months):

Holding costs: 24 months
Finance costs: Full term at construction rates
Opportunity cost: Capital tied up longer

Modular (8 months):

Holding costs: 8 months
Finance costs: 1/3 the duration
Opportunity cost: Earlier return to capital

For a $3M Project:

Traditional holding costs (24 months): ~$180,000
Modular holding costs (8 months): ~$60,000
Savings: $120,000 (before finance cost savings)

The Real Cost Advantage

Modular construction’s cost advantage isn’t lower construction prices. It’s:

Certainty: Fixed price contracts eliminate budget blow outs
Speed: Shorter timelines reduce holding and finance costs
Quality: Factory production reduces defect rectification
Risk: Predictable delivery protects investment timelines

Financing Modular Construction

How Modular Finance Differs

Traditional construction loans release funds progressively as building stages complete. Modular construction requires different financing structures because significant work happens in the factory before anything appears on site.

Typical Modular Payment Structure:

Contract signing: 10%
Factory commencement: 30%
Module completion: 30%
Site delivery: 20%
Practical completion: 10%

Finance Options

Construction Loans: Some lenders now offer modular specific construction loans recognising factory progress. Specialist lenders like Abacus understand modular workflows.

Development Finance: For multi dwelling projects, development finance covers land acquisition and construction with interest only periods.

Asset Finance: Some projects use asset finance for factory components, treating modules similarly to equipment finance.

Finance Cost Comparison

For identical $1.5M construction:

Traditional (18-month draw):

Average balance: ~$750,000
Interest (7%): ~$78,750

Modular (6-month draw):

Average balance: ~$750,000
Interest (7%): ~$26,250
Savings: ~$52,500

Stage 3: Detailed Quote Fixed price construction quote covering all inclusions. Valid for specified period (typically 60-90 days).

Red Flags in Pricing

Be cautious of:

Quotes significantly below market rates (often exclude essentials)
Vague inclusions without specifications
Excessive provisional sums
No fixed price option
Unwillingness to detail what’s included

Frequently Asked Questions

Is modular construction cheaper than traditional?

Total project cost (including timeline savings) typically favours modular. Raw construction costs are similar, but certainty and speed create real savings in holding costs, finance, and risk.

What’s not included in modular quotes?

Standard exclusions include: land costs, site works (demolition, foundations, services), approval fees, council contributions, professional fees, and landscaping beyond basic provisions. Always confirm inclusions in writing.

Can I reduce costs by choosing a smaller design?

Yes, but there’s a minimum viable project size for modular efficiency. Very small projects may not achieve cost advantages over traditional construction. Multi dwelling developments offer the best value.

How do I budget for contingency?

For well planned modular projects, 5% contingency is typically adequate. Traditional construction often requires 10 to 15%. Site works carry more uncertainty than factory construction. Allocate contingency accordingly.
