What star rating should I expect from a good building designer in Perth?
The median Google rating across the 89 building designers & draftspeople Starworks ranks in Perth, WA is 5.0 stars, and 80 of them sit at 4.5 or above. A rating at or near that median is ordinary for building designers & draftspeople in Perth, WA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established building designer in Perth have?
The median building designer Starworks ranks in Perth, WA carries 3 Google reviews. The most-reviewed of them carries 68.
How does Starworks rank building designers & draftspeople in Perth?
Starworks gives every building designer in Perth, WA a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a building designer in Perth with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer building designer with a handful of excellent reviews may still be the right choice in Perth, WA. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same building designer not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 50 distinct building designers & draftspeople in Perth, WA rather than a longer list of repeats.
How often is this list of building designers & draftspeople in Perth updated?
This ranking of building designers & draftspeople in Perth, WA rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my building designer business ranking in Perth?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median building designer Starworks ranks in Perth, WA carries 3 Google reviews at 5.0 stars.
