Adelaide building design & construction
We design it. We build it.
New homes, extensions and renovations — designed around your site and budget, lodged for council approval, then built by the same team. Or take the plans to your own builder. Your call.

Stages
From a first sketch to the keys in your hand.
You can start or finish at any stage; there's no obligation to go the whole way. Some clients come to us just to build, some just need approvals, others want us from first sketch to handover.
- Stage 01
Concept Design
Including a feasibility cost estimate.
Concept is as light or as thorough as your project needs: a drafting pass to confirm a layout, or a look at options. A construction estimate sits with the first sketch, so you know early what the design might cost.

Planning Approval
We prepare the planning set, lodge it with council, and manage the correspondence. On complex sites we ask early — slope, bushfire, heritage, septic — so the application doesn't stall.
- Stage 03
Building Approval
Building Rules Consent, or BRC.
The design gets its technical detail — engineering, timber framing, energy compliance — and a drawing set ready for certification. If you're building with us, the stage ends with an itemised quote.
- Stage 04
Construction
A dedicated site supervisor, regular updates with photos, and the drawings you approved as the drawings on site. It ends at handover with keys, warranties and certificates.
Why Lumea
Drafted around you, not a template.
Every plan starts with your brief, your site and your budget. We draft what suits the way you live — then document it to the standard your builder and your council both need.

Common questions
What does a building designer do?
A building designer plans and documents homes, renovations and extensions. We work out what will fit on your site and suit how you live, then produce the drawings your council needs to approve the build and your builder needs to price it.
How much does building design cost?
It depends on the size and complexity of the project and how much documentation you need. We don't quote before we understand the job, which is why the first consultation is free and carries no obligation. After it, you get a clear price for the work up front rather than an hourly rate that drifts.
How long does the design and approval process take?
Most projects run six to ten weeks from first concept to lodgement. How fast concepts get signed off is usually the biggest variable, followed by whether engineering or energy ratings are involved. Council assessment time sits on top of that and is outside our control.
Do you handle council approvals?
Yes. We prepare the full documentation set and lodge it through the PlanSA portal on your behalf, then manage any requests for further information that come back. Chasing approval is our job, not yours.
Do I need approval for a renovation or extension?
Usually yes. Most structural work, extensions and changes to the building footprint need consent, and some smaller work is exempt. Rather than guess, send us what you're planning and we'll tell you what approvals it triggers before you spend anything.
What drawings do I actually receive?
A typical set includes a site plan, floor plans, elevations, sections and construction details, plus specifications if you're going to tender. We draft to the level of detail your builder needs to quote accurately, because vague drawings are where variations and budget blowouts start.
Will I need an engineer or an energy rating too?
Most construction documentation does need both. We coordinate those consultants alongside the design so you deal with one point of contact instead of three, and so compliance is resolved as we go rather than forcing a redesign late.
Can you design for a sloping or difficult block?
Yes. Slope, orientation, access and council setbacks all shape what's possible, and working that out early is far cheaper than discovering it after a builder prices the job. Difficult sites are usually where thoughtful design earns its keep.
Can you work with my builder, or help me choose one?
Both. If you have a builder, we document to suit the way they work and stay available through construction. If you don't, our construction specification and tender service prepares a detailed spec and runs the tender, so you're comparing like-for-like quotes instead of three different scopes.
Can I change my mind after seeing the concept?
That's what the concept stage is for. Concepts exist so you can react to something real and refine it before it becomes a full documentation set. Changes are far cheaper on paper than once drawings are complete or construction has started.
What areas do you service?
We're based in Adelaide and work across the metropolitan area and greater South Australia, including the Hills and regional areas.
How do I get started?
