Building a new home is an exciting journey, but one of the first questions on every prospective homeowner’s mind is: “How long will this actually take?” The simplified answer is that building a house in Perth typically takes between 12 and 24 months from initial planning to handover.
Single-storey homes generally sit at the shorter end (around 12-16 months), while double-storey or more complex custom builds can extend to 18-24 months.
But here’s what matters most: knowing where that time goes, what can slow things down, and how to keep your project on track.
Key Takeaways — Perth House Build Timeline
- Total time: 12–24 months from planning to handover
- Pre-construction alone takes 4–8 months before any building starts
- Single-storey: ~12–16 months | Double-storey: ~18–24 months
- Biggest delay causes: weather, trades shortage, mid-build design changes
- Using a building broker doesn’t cost you extra — builders absorb the fee
- Buffer tip: add 2–3 months to any timeline you’re given

| Slab & Framing | 4 – 6 Weeks | 8 – 12 Weeks (inc. upper floor) |
| Brickwork & Roof | 8 – 10 Weeks | 12 – 16 Weeks |
| Lock-up & Internals | 12 – 16 Weeks | 16 – 20 Weeks |
| Estimated Total | 12 – 16 Months | 18 – 24 Months |

Breakdown of the Build Timeline
Pre-Construction Phase (4-8 Months)
Before a single brick is laid, there’s significant groundwork to complete. This phase includes the following.
Design and Planning (1-2 months)
Working with architects and designers to finalise your floor plans, elevations, and material specifications. Custom designs naturally take longer than selecting from standard plans, as they require multiple iterations to get everything right.
Permit Acquisition (1-2 months)
Securing building permits, environmental approvals, and utility connections from local councils. This administrative process can’t be rushed, and incomplete applications only create delays.
Builder Selection (2-4 weeks)
Choosing the right builder for your project is crucial. This involves comparing quotes, reviewing portfolios, and ensuring the builder’s experience matches your home’s complexity.
Site Preparation (2-4 weeks)
Site surveys, soil testing, and clearing the land for construction. Unexpected site conditions, like poor soil quality or drainage issues, can add time here.
Financial Arrangements (2-4 weeks)
Finalising your construction loan, reviewing contracts, and ensuring all financial documentation is in order.
Construction Phase (9-15 Months)
Once approvals are secured and contracts signed, the physical build begins.
Foundation and Framing (6-8 weeks)
Pouring the slab and erecting the frame. In Perth, double-brick construction is standard, which takes longer than the timber framing used in eastern states but delivers superior durability and thermal performance.
Bricklaying and Roofing (8-12 weeks)
Building the external walls and installing the roof. This stage is particularly vulnerable to weather delays during Perth’s winter months.
Lock-Up Stage (4-6 weeks)
Installing windows, external doors, and completing weatherproofing. Your home is now secure from the elements.
Plumbing and Electrical (6-8 weeks)
Rough-in work for plumbing, electrical, and HVAC systems, followed by inspections.
Interior Finishings (8-12 weeks)
Installing cabinetry, benchtops, flooring, painting, and all the details that transform a structure into a home.
Final Inspections and Handover (2-4 weeks)
Final building inspections, defect rectification, and preparing your home for handover.
What Can Delay Your Build?
Even with the best planning, several factors can extend your timeline.
Weather Conditions
Perth’s winter rains can halt outdoor work, particularly during the foundation, bricklaying, and roofing stages. Builders typically build buffer time into schedules, but extended wet periods can still cause delays.
Material and Trade Shortages
The construction industry continues to face supply chain challenges and skilled labour shortages, particularly for bricklayers and specialist trades. According to recent industry reports, these shortages have normalised longer build times compared to pre-2020.
Design Changes Mid-Build
Changing your mind after construction begins creates delays and cost increases. Every modification requires new approvals, material orders, and schedule adjustments.
Site-Specific Challenges
Sloping blocks, narrow lots, or properties requiring retaining walls add complexity and time to the build process.
Council Approval Delays
Backlogs at local councils can extend the permit approval phase, particularly during busy periods.
How Building Brokers Reduce Delays and Keep Projects on Track
This is where working with a building broker makes a measurable difference to your timeline and overall experience.
Expert Builder Matching
Not all builders are the right fit for your project. Some excel at custom homes, others at investment properties or first home builds. A building broker matches you with builders who have proven experience in your specific project type, reducing the risk of delays caused by inexperience or capacity issues.
At Better Way 2 Build, we maintain relationships with a carefully selected panel of quality builders across Perth. We know their strengths, their current workloads, and their track records for on-time completion.
Streamlined Pre-Construction
The pre-construction phase is where most first-time builders lose time through incomplete applications, unsuitable builder selections, or unrealistic design expectations. Building brokers guide you through this phase efficiently, ensuring:
- Your design is buildable within your budget
- All permit applications are complete and accurate
- Financial arrangements are in place before construction begins
- Site preparation is properly planned and executed
Proactive Problem-Solving
Experienced building brokers anticipate common delays before they happen. We help you make decisions early, like material selections and colour choices, that would otherwise hold up construction later. We also maintain communication with your builder throughout the process, addressing potential issues before they become costly delays.
Realistic Timeline Expectations
One of the biggest sources of frustration in home building is unrealistic timeline promises. Some builders quote optimistic timeframes to win contracts, only to disappoint clients later. Building brokers provide honest, realistic timelines based on current market conditions, your specific project, and the builder’s actual capacity.
No Extra Cost to You
Here’s the best part: our services don’t add time or cost to your project. Builders pay us a set fee equivalent to their internal sales commission, meaning your home costs the same, or often less, than going direct to a builder. You get expert guidance and advocacy throughout the entire process at no additional expense.
Tips for Keeping Your Build on Schedule
Whether you work with a building broker or not, these strategies help minimise delays.
Finalise Your Design Early
Make all major design decisions before construction begins. Changes during the build are the single biggest cause of timeline blowouts.
Choose Your Finishes Promptly
When your builder requests selections for tiles, fixtures, colours, and fittings, respond quickly. Delayed selections mean delayed ordering, which pushes back installation.
Maintain Regular Communication
Stay in touch with your builder throughout the process. Regular site visits and progress updates help identify and resolve issues early.
Build in Buffer Time
If you need to move in by a specific date, don’t plan for the minimum timeline. Add at least 2-3 months of buffer to account for unexpected delays.
Work With Experienced Professionals
This applies to your builder, architect, and any consultants involved in your project. Experience translates directly to fewer surprises and smoother execution.
