ENGINEERING CERTAINTY. DELIVERED.
Planning to make your home bigger? Engineering On Demand provides structural engineering for Home Extensions Perth, helping homeowners, builders and designers transform existing houses with practical, buildable structural solutions.
Extending an existing home requires careful consideration of both the new construction and the structure already there. Existing walls may need to be removed, roof framing modified, new foundations constructed and new structural elements connected back into the original building.
As your Home Extension Engineer Perth, we can assess these requirements, develop the structural design and prepare clear engineering documentation for construction.
Your architectural plans show what you want to build.
Structural engineering determines how it can be supported and constructed.
As your Home Extension Engineer Perth, Engineering On Demand can work alongside your builder, architect or building designer to develop the structural elements required to make the proposed extension possible.
This can involve engineering everything from the new foundations through to beams, walls, framing and roof structure.
Where the extension modifies the existing home, we can also determine what structural alterations or strengthening may be required.
Extend your living space into the backyard with engineering for new foundations, walls, structural openings and roof systems.
Structural design for additional bedrooms, living spaces, garages and other extensions alongside the existing home.
Create larger kitchen, dining and living spaces using engineered beams and structural supports where existing walls need to be removed.
Structural engineering for additional bedrooms, bathrooms and associated residential spaces.
Engineering for larger entertaining and living areas, including wide openings and connections to outdoor areas.
Engineering for attached garages, workshops and other extensions integrated with the existing home.
Many modern Building Extensions Perth involve opening the rear or side of the existing home to create one large connected living space.
Rather than simply removing the wall, our engineers can determine what it supports and design an appropriate replacement structure.
This may include:
LOAD-BEARING WALL → ENGINEERED BEAM → COLUMNS/SUPPORTS → FOUNDATIONS
The result can be a substantially wider opening while maintaining the structural integrity of the home.
Structural work associated with extensions needs to be considered within the regulatory requirements applying to the project.
The Australian Building Codes Board publishes the National Construction Code, which establishes minimum requirements for the safety, health, amenity, accessibility and sustainability of buildings in Australia.

Our engineering documentation is developed with consideration of applicable NCC provisions and relevant Australian Standards for the particular project.
Depending on the extension, structural engineering may form only one part of the documentation required before construction.
Your project may also require:
Engineering On Demand can coordinate engineering with these supporting services, reducing the need to manage multiple separate consultants.
Structural engineering will commonly be required where an extension introduces new structural elements or modifies the existing load-bearing structure. This can include footings, slabs, beams, columns, roof framing and wall removals.
A Home Extension Engineer Perth assesses the structural requirements of the proposed extension and designs the structural elements required to support it and integrate it with the existing home.
Yes. If the wall is load-bearing, an engineer can assess the loads and design an appropriate beam and supporting structure to replace it.
Yes. Our Residential Extensions Perth services cover structural engineering for rear extensions, side extensions, additional rooms, larger living spaces and other residential extension projects.
Yes. Where included within the project scope, structural engineering can cover the new footings, slabs and supporting structure required for the extension.
Yes. Our engineers and drafting team can prepare detailed structural drawings documenting the engineering solution.
Yes. Depending on the project, Engineering On Demand can also assist with drafting, certification and the council approval process.
