Construction Company in Perth metro
Perth's construction sector covers a lot of ground: new home builds, extensions, commercial fit-outs, renovations, and structural work like retaining walls, slabs, and additions. Some firms specialise in one type of project, such as knockdown-rebuilds in the northern suburbs or duplex builds close to the coast, while others run a broader operation covering everything from council approvals through to handover. We're tracking 114 construction companies across the Perth metro area, ranging from small owner-operator outfits to larger builders with dedicated project managers and in-house trades.
What to look for before you sign a contract
Check that the builder holds a current registration with the Building Services Board and carries home indemnity insurance where required. Ask to see recent completed jobs, ideally ones similar in scale to yours, and speak to those clients directly rather than relying on photos alone. Get a fixed-price or cost-plus contract in writing with a clear provisional sums schedule, since vague allowances for items like tiling or fixtures are where budgets blow out. Timeframes matter too: ask for a realistic build schedule and what happens if trades or materials are delayed.
How we score builders
Our ranking weighs review consistency over time, responsiveness to enquiries, and how well a company's public track record matches what clients report after the build. It's not just a star average. For the full breakdown of factors and weighting, see our methodology page. If you want a shortlist rather than the full directory, our ranked guide to the best construction companies in Perth narrows the 114 down to the ones worth calling first.

Common questions about construction company
- How much does a construction project typically cost in Perth?
- It depends heavily on scope. A basic single-storey home build might run from roughly $1,800 to $2,500 per square metre depending on finish level, while renovations and extensions are usually quoted per project after a site visit. Always ask for a written itemised quote rather than a rough verbal estimate.
- How long does a typical build take?
- A standard new home build in Perth usually takes 6 to 12 months from slab to handover, depending on design complexity, weather, and how busy the builder's trades are. Extensions and renovations can range from a few weeks to several months.
- What should I expect during the build process?
- Expect a sequence of stages: site works and slab, frame, lock-up, fixing (plumbing, electrical, cabinetry), and finishing. A reliable builder will give you a payment schedule tied to these stages and keep you updated at each milestone rather than going quiet for weeks at a time.
- How do I judge the quality of a construction company before hiring them?
- Look past the marketing and check licensing status, ask for references from the last 12 months, and visit a site they're currently working on if possible. Consistent communication, tidy site management, and a willingness to explain the contract in detail are strong signs of a builder worth trusting.
