Builders – Western Australia

Why work with a registered builder in Western Australia?

Commissioning a new build or major renovation is a significant investment, so choosing the right professional matters. In WA, all builders carrying out work valued at $20,000 or more must be registered with the Building Services Board. Registration proves that the company or individual meets minimum technical, financial and management standards. It also gives you access to statutory home indemnity insurance, providing an extra layer of protection if the builder cannot complete the job.

Project types WA builders can deliver

• Custom homes: From coastal retreat to urban infill, a custom builder tailors every square metre to your lifestyle.
• House & land packages: Volume builders streamline the process and often negotiate competitive land prices.
• Major renovations & extensions: Add space, value and efficiency without relocating.
• Commercial construction: Offices, retail, hospitality and light industrial—delivered to BCA standards.
• Multi-residential & mixed-use: Medium-rise apartments, aged-care facilities and student housing.

Key selection criteria

1. Licensing, insurance & track record

Always ask for a copy of the builder’s registration certificate and current home indemnity insurance. Vet recent projects, check references and read independent reviews on ArchiPro.

2. Local climate expertise

Western Australia spans cyclonic zones in the north and cool temperate regions in the south. A builder experienced in your micro-climate will specify the right materials, insulation and bush-fire compliance measures.

3. Supply chain & trades network

Delays often stem from labour or material shortages. Established builders maintain deep relationships with WA subcontractors and suppliers, helping keep your programme on schedule.

Typical design-and-build process in WA

1. Pre-design: Establish budget, site constraints and a high-level brief—sometimes with the help of construction consultants.
2. Concept & planning approval: Preliminary drawings, energy assessments and submission to the local council.
3. Detailed design & tender: Builders collaborate with architects or building & construction specialists to finalise documentation.
4. Contract signing: Fixed-price, cost-plus or design-build contracts; understand provisional sums and prime cost allowances.
5. Construction & quality assurance: Site works, trade coordination, staged inspections and handover.

Budget benchmarks & contract types

In Perth, a turnkey single-storey custom home typically starts around $1,800–$2,400 per square metre, while high-end coastal builds can exceed $4,000/m². For renovations, allow $2,000–$3,000/m², plus contingency for hidden structural surprises. Discuss cost escalation clauses and payment schedules in detail before signing.
