Engineering & Design Solutions for South Australian Homes
Residential design, structural engineering and building approvals, delivered with practical advice and clear documentation.
Building a home shouldn’t feel like managing five different companies
Most people building or renovating in Adelaide end up juggling a designer, a drafter, an engineer, a council and a builder. Each one waits on the next. Plans bounce back and forth. Costs creep up. And when something goes wrong, nobody’s quite sure whose job it was to fix it.
We do it differently. Our team designs your home, engineers it, takes it through council approvals and builds it. You deal with one business that owns the whole result, from the first conversation to the day you get the keys.

What would you like to build?
A new home or knockdown rebuild
Whether you’ve got a vacant block or an old house that’s past its best, we’ll design a home that fits your land, your budget and the way you live.
A renovation or extension
More space, more light, a better layout. We’ll design and engineer changes that work with your existing home and handle the approvals too.
A granny flat or small development
Adding a secondary dwelling or splitting your block? We’ll show you what your land can do, then design, approve and build it.
Plans and engineering only
Already have a builder? Builders, owner-builders and developers can use our design, drafting and engineering services on their own.
Why Adelaide homeowners work with us
- 01
One team, sketch to keys
Your designer, engineer and builder work side by side, so your plans are buildable from day one. There’s no finger pointing and no information lost between consultants, just one team that’s responsible for getting it right.
- 02
Know your numbers before you sign
We design and engineer your home first. Then we give you a final quote based on detailed drawings, not a rough estimate. That means fewer surprises once construction starts.
- 03
Engineering at the heart of every home
Many Adelaide suburbs sit on reactive clay soils that swell when wet and shrink when dry. Getting the footings, structure and drainage right for your site is what keeps a home solid for decades. It’s where we start.
- 04
SA approvals, handled
Planning Consent, Building Consent, Development Approval. We know the PlanSA system and we manage every step, so you don’t have to work it out on your own.
- 05
Straight answers, regular updates
You’ll have one main contact who keeps you informed at every stage. [CLIENT TO CONFIRM: how often clients receive updates, e.g. weekly, so we can state it here.]
