Clause-by-Clause Design Review

We read your design like the NCC will. Our reviews are clause-specific, so you’ll know exactly what passes, what doesn’t, and what needs rework, no guesswork.

Compliance Summary for DA/CC

You’ll get a project-ready BCA compliance report that satisfies DA and CC submission needs, without overwhelming the design team with regulation jargon.

DTS vs Performance Mapping

We flag where your design follows DTS and where it leans on a performance pathway, so you’re not blindsided by extra approvals or consultant input.

Pre-lodgement Architect Support

We sit with your team before lodgement to help rework high-risk areas. No formalities, just practical advice that can prevent months of delays later.

Step 1

Start With Your Drawings

Send us your current plans and we’ll begin a clause-by-clause compliance review—no NDAs, no long forms, just the real work.

Step 3

Architect Review Sessions

We walk through the design with you. Flag issues. Triage upgrades. Resolve grey areas before they become redesigns.

Why Choose Us?

  • You’ll Know Where Your Design Stands

We don’t just tick boxes, we tell you, clause-by-clause, where your design holds up and where it’ll trigger issues later. It’s upfront clarity, not post-lodgement surprises.

  • We Don’t Send You Back To The Drawing Board

You don’t want vague feedback or sweeping redlines. We work with your design intent and offer targeted fixes, so compliance doesn’t undo the concept.

  • We Flag Knock-On Effects Early

A change to glazing or floor area can trigger a ripple of other BCA upgrades. We catch those flow-on effects early, especially in large or sustainable builds.
