ENGINEERING CERTAINTY. DELIVERED.
Adding to an existing home means connecting new construction to a structure that was never necessarily designed for it.
Engineering On Demand provides structural engineering for Home Additions Perth, helping homeowners, builders and designers develop safe, practical structural solutions for extensions, additional rooms, second-storey additions and other residential alterations.
Our engineers can assess the existing structure, design the new structural elements and prepare the engineering documentation required to take your addition from architectural concept through to construction.
Whether you need a Home Extension Engineer Perth, engineering for a major renovation or a Structural Engineer for Additions, our team can help determine how the new and existing structures work together.
A home extension changes more than the footprint of your house.
Existing walls may become internal openings, roof structures may need modification and new loads may need to be transferred through existing or newly constructed structural elements.
As your Home Extension Engineer Perth, we assess how the proposed extension affects the existing structure and design the structural elements required to support the new construction.
Our goal is to provide an engineering solution that satisfies the structural requirements while remaining practical for your builder to construct.
New walls, columns and structural elements may require additional foundations designed for the loads and site conditions.
Creating larger connections between the existing home and extension can require load-bearing walls to be removed and replaced with engineered beams.
Structural members may be required to support roofs, upper floors and large openings.
Extending or modifying an existing roof can change its structural arrangement and load paths.
The new addition needs to be appropriately connected to the existing building.
Changes to walls and framing can affect the building’s existing bracing system and may require new structural solutions.
Steel beams, columns and frames may be required where longer spans or significant loads are involved.
One of the most common structural challenges with a home extension is creating a large opening between the original house and the new space.
If the existing wall carries roof, floor or other structural loads, it cannot simply be removed.
Our engineers can determine the loads supported by the wall and design an appropriate beam, lintel, columns and connections to transfer those loads safely.
This can allow homeowners and designers to achieve larger open-plan areas while maintaining the structural integrity of the building.
Structural engineering is often only one part of preparing an addition for construction.
Depending on the scope of work, your project may also require drawings, building certification and a building permit, while some proposals may also require development approval.
Engineering On Demand can assist with the broader council approval process where required.
For authoritative information about building approvals in Western Australia, the WA Government provides guidance on building permits and the state’s building approval system.
If the addition involves new structural elements or modifications to the existing load-bearing structure, structural engineering will commonly be required. This can include foundations, beams, columns, wall removals, roof alterations and connections between the existing and new structures.
Yes. Our Home Extension Engineer Perth services cover structural engineering for additions and extensions to existing homes.
Potentially, but an existing external wall may support roof, floor or other structural loads. A structural engineer can assess the proposed opening and design the necessary supporting structure.
Yes. Second-storey additions may require assessment of the existing structure as well as engineering for new floors, beams, columns, bracing, roof framing and potentially foundation strengthening.
Yes. We can provide structural Engineering Drawings documenting the engineered solution for the addition.
Yes, where required by the engineering scope. A structural inspection can help establish existing conditions where adequate drawings or other information aren’t available.
Yes. Engineering On Demand can also assist with drafting, building certification and council approval requirements associated with additions and extensions.
