How it works

Design is where every good renovation starts.

We run the full four-stage process for you — or you can start with just the design, take the drawings, and see us again when you need the next stage.

DesignFrom first call to draft plans

Most renovation projects live or die at the design stage. Get it right and the build is predictable. Get it wrong and you spend the whole project fighting fires.

Why PlanBuild

One team instead of four

Most homeowners end up hiring a surveyor, an architect, a structural engineer and a builder separately. We handle the package.

Fewer handoffs

One team manages survey, plans, engineering, building control and install. No chasing three separate companies.

Faster decisions

Everything is coordinated in-house. Decisions happen faster and nothing falls between the cracks.

Cleaner communication

One point of contact throughout the project. No repeating yourself to different trades.

One clear path

From first enquiry to completed alteration, you always know what happens next and what it costs.

Team of professionals reviewing construction plans together

Rather not call?

Drop your details and we'll call you back.

Three short fields. Same person who picks up the phone will ring you — usually within 30 minutes in business hours.

Before you start

Common questions

Do I need structural calculations?+

If you are removing or altering a load-bearing wall, yes. A structural engineer must design the replacement support — typically a steel beam (RSJ) with padstones. We handle this as part of the package.

Do I need building control for removing an internal wall?+

Yes. Any structural alteration requires a building control application. The inspector will check the steelwork before it is covered up. We manage the full process from application to sign-off.

Can you install the steel as well?+

Yes. We provide the full package — survey, plans, engineering, building control and installation. You do not need to find a separate contractor.

Can you help with kitchen knock-throughs?+

Absolutely. Kitchen-to-dining and kitchen-to-living knock-throughs are our most common job. We assess the wall, design the opening, install the steel and make good.

What happens at the site visit?+

The on-site visit runs for around 2 to 3 hours. A qualified engineer walks the space with you, checks the wall construction, assesses the load path and captures a millimetre-accurate 3D point cloud scan of the relevant rooms. You'll get a verbal summary before we leave and draft plans 5 to 10 working days later.

How quickly can you provide plans and calculations?+

Draft floor plans are typically delivered within 5 to 10 working days of the on-site visit. If structural calculations are needed, those follow within about a week after the plans are signed off. If you need it faster, ask about priority turnaround.

Can I take the drawings to another builder?+

Yes — absolutely. The drawings are yours to keep. Most of our clients do come back to us for the build because we've engineered it and we can warrant the work end-to-end, but you're under no obligation. At the quote stage we'll happily put our construction quote alongside two or three other builders quoting against the same spec, so you can compare fairly.

One call. One team. One point of accountability.

15 minutes on the phone and you'll know exactly what your project needs. No sales pitch, no obligation.
