Removing an internal wall can dramatically improve your home’s layout and function—but if it’s structural or load-bearing, you’ll need council approval before touching a single brick. At Engineering On Demand, we simplify the process with expert assessments, certified engineering plans, and fast, accurate documentation to ensure your wall removal project is fully compliant and risk-free.
Whether you’re opening up a kitchen, joining two rooms, or upgrading an older layout, we’re here to help you get it approved—quickly and correctly.
Yes—Any modification tot he internal structure of your home requires a Building Permit, regardless of wether it is structural or not, under the WA Building Act 2011. The wall must also comply with structural requirements under the National Construction Code (NCC).

We liaise with your local council (e.g. City of Perth) to submit your building application.
Ongoing Support
We work with your builder to ensure safe removal and sign-off if needed.
Wall removal might look simple, but incorrect removal of load-bearing structures can lead to:
🛑 Roof sagging or collapse
🛑 Cracked walls and structural damage
🛑 Insurance claim rejection
🛑 Heavy council fines and rectification orders
Our Wall Removal Engineering Services ensure all support elements are identified and replaced with certified beams, lintels, or posts to maintain your building’s safety and compliance.
