Melbourne renovation and extension project under construction with scaffold

Renovation Engineering

Structural engineering for renovations, extensions and existing homes.

Linfinity Engineering helps architects, builders and homeowners assess existing structure, coordinate new openings and document practical strengthening for renovation and extension projects.

We support alterations, additions, upper-storey extensions, rear extensions, wall removals, steel beams, footing checks and staged construction advice where existing structure must work with the new design.

Existing structure assessment

Service Fit

Good fit for projects joining old structure to new work

Renovation engineering is most useful when existing walls, footings, roof framing or floor framing affect the new architectural intent.

Alterations and additions

Structural design for wall removals, new openings, new beams, additions and layout changes inside existing homes.

Existing-structure assessment

Review of existing framing, foundations, load paths and site constraints before the renovation scope is locked in.

Strengthening and remedial work

Practical strengthening advice where existing members, footings, retaining interfaces or damaged elements need structural assessment or design.

Construction sequencing

Advice for builders and owners where temporary support, staged demolition or access constraints affect buildability.

Deliverables

Typical renovation engineering outputs

  • Structural drawings and details for alterations, additions and extensions
  • Beam, lintel, column, footing and bracing design where required
  • Existing-structure assessment notes and strengthening recommendations
  • Construction-stage sequencing advice for practical site delivery
  • Coordination with architects, builders, certifiers and owners

Melbourne Support

Based in Camberwell, working across Melbourne.

Linfinity Engineering supports homeowners, builders, architects and developers across metropolitan Melbourne and wider Victoria by arrangement.

Process

From existing conditions to a buildable renovation detail.

01

Review existing and proposed information

We look at architectural drawings, photos, site information, existing structural drawings where available and the intended renovation scope.

02

Resolve the structural changes

We clarify what is being removed, retained, strengthened or added so the new work has a clear load path.

03

Document the buildable solution

The outcome supports permit, pricing and construction workflows with practical details for the renovation stage.

Common Questions

Questions before you send drawings or site details.

Send the project context

Upload drawings, site photos, surveys, reports or a short note about what you need. Linfinity will review the scope and respond with the right next step.

Start an Enquiry
Can you assess whether a wall can be removed?

Yes. Linfinity can review drawings, photos and site conditions to determine whether a wall is structural and what beam, support or strengthening may be required.

Do renovation projects need a site inspection?

Some projects can start from drawings and photos, while others need inspection where existing structure, cracking, movement or hidden framing conditions are important.

Can you work with my architect or builder?

Yes. Linfinity regularly coordinates renovation and extension engineering with architects, building designers, builders and homeowners.
