How to Build a House in Perth: Step-by-Step Guide for First-Time Buyers
Building your first house in Perth runs six clear steps: set a budget, secure land, pick a builder or broker, finalise design and council approvals, work through construction stages, then take handover. Each step has its own paperwork and cost, so plan the order before you sign anything.
1. Set your real budget
Your build budget is more than the builder's base price. Add land, site works, stamp duty, connections, landscaping, and a contingency of roughly 5 to 10 percent for the surprises that appear once digging starts. Get finance pre-approval first so you know your ceiling before you fall for a display home.
What people forget to cost
- Site costs: slope, rock, fill, and retaining walls.
- Service connections for power, water, and sewer.
- Fencing, driveways, and landscaping after handover.
- Bank valuation and progress-payment interest during the build.
2. Find and secure land
Land shapes the whole build. A flat, rectangular lot on serviced streets is cheaper to build on than a sloped or narrow block. Check zoning, easements, and the developer's design guidelines before you commit, because those rules can force a specific facade, roof pitch, or setback.
3. Choose a builder or broker
You can go direct to a builder or work through a building broker who compares builders on your behalf and matches a design to your block. Ask for a fixed-price contract, a written inclusions list, and referees you can call. Compare like for like: two quotes at different prices often hide different inclusions.
4. Design and approvals
Once you pick a design, it goes through working drawings, engineering, and then approvals. Expect building permit sign-off plus any development approval your estate or council requires. This stage is slow, so keep decisions moving; every change to the plan after this point costs money and time.
5. Construction stages
Most Perth builds progress through five payment stages, each paid as the work finishes.
- Slab: site prep and the concrete footing.
- Plate: external walls up to roof height.
- Roof: roof framing and cover on.
- Lock-up: windows and external doors in.
- Fixing and completion: internal fit-out, then finishes.
Inspect at each stage or send an independent inspector. Faults are far cheaper to fix before the next stage covers them.
6. Handover and defects
At handover you do a final walk-through and list every defect before you accept the keys. Reasonable defects get fixed under your maintenance period. Keep all paperwork, warranties, and the compliance certificates, because you will need them if a problem shows up later or when you sell.
Common first-buyer mistakes
- Signing before finance is confirmed.
- Comparing quotes without matching the inclusions.
- Ignoring site costs on a cheap but tricky block.
- Making design changes after approvals are lodged.
- Skipping stage inspections to save a few dollars.
