Expert Structural Engineering Consultants in Perth

Solid Engineering & Structural Design

Our Approach as Structural Engineers in Perth

SOLID Engineering & Structural Design is your trusted Perth-based partner, delivering excellent residential, commercial and industrial structural engineering services with clear and efficient communication from project inception to completion. Our team members are always fully attentive and ready to listen for providing safe and cost-effective structural solutions tailored to our Client’s expectation.

We’re not flashy. We’re careful.

At SOLID, we don’t sign off just to keep things moving. And we don’t treat buildings like checklists.

We care deeply about getting it right, even when no one’s looking; each project we take on is handled with meticulous care and attention.

Our designs are optimised, not overdone, never unsafe. We do exactly what should be done: no more, but definitely no less.

If cutting construction costs matters more to you than long-term safety, we may not be the right fit. But if you value thoughtful design, clear documentation, and a structure that will stand the test of time, we’d love to talk.
