Townhouse and multi-unit developments need structural engineering across footings, party walls, suspended slabs and basements — designed for compliance, buildability and efficient staged construction. For developers and builders, the right engineering input early can shape both the program and the bottom line.
Here's what to expect from a structural engineer on a multi-unit project.
What developers need from a structural engineer
Beyond a sound design, developers need an engineer who understands the commercial realities: efficient structural solutions that don't over-build, documentation that satisfies the building surveyor first time, and coordination with architects, town planners and builders. Early engineering input helps avoid expensive surprises once construction starts.
Key structural elements
Multi-unit developments commonly involve:
- Footings designed for the soil and for structure near boundaries
- Party walls between dwellings, meeting structural, fire and acoustic requirements
- Suspended slabs over garages, basements or between levels
- Basements and retaining where car parking or storage goes below ground
- Lateral systems to resist wind and other loads across taller or longer buildings
Coordinating with the project team
On multi-unit work, structure is one piece of a bigger puzzle. The engineer coordinates with the architect's layout, the builder's methods and the surveyor's requirements — and often phases the documentation to suit a staged construction program. Smooth coordination keeps the project moving.
Designing for efficiency
A good structural design balances safety and compliance with efficiency — sizing members and systems so the build is economical and practical without cutting corners. That's where genuine commercial experience pays off. Our commercial and industrial engineering team delivers exactly this across Melbourne.

Frequently asked questions
What does a structural engineer do on a townhouse project? Designs the footings, party walls, slabs, framing and any basement or lateral systems, and produces the documentation for the building permit — coordinated with the wider team.
When should developers engage a structural engineer? Early, as the design develops — early input shapes a more efficient, buildable structure and avoids costly changes later.
How are shared walls between units engineered? As party walls meeting structural, fire and acoustic requirements, with footings and isolation designed between dwellings.
What structural factors affect a multi-unit build? Soil and footings, party walls, suspended slabs, basements/retaining, and lateral load systems — all influence cost and program.
