The Rising Cost of Home Building in WA and the Importance of Efficient Engineering

New data from Master Builders shows the cost of building a new home in WA is now about 95–96% higher than in 2019, the biggest escalation in the country. A home that cost $300,000 to build in 2019 would now be closer to $570,000–$586,800, so every inefficient detail or over‑designed element has a much larger impact on your budget than it did a few years ago.

Not all engineering is created equal: some designs simply meet minimum compliance, while others are carefully refined to use materials efficiently and suit how local builders actually construct.

In the current cost environment, choosing a trusted firm that delivers considered, buildable engineering can be the difference between a project that stays on budget and one that quietly blows out
