The Pattern Book

The Canberra House Pattern Book offers pre-approved designs for $1,000, and projects using them proceed without a development application.

Be precise about what this saves, because the usual claim is wrong. The planning register shows the assessment clock on a multi-dwelling DA runs a median of about 93 days, not the twelve to eighteen months people quote — see Time is a cost. So the pattern book does not save you eighteen months of assessment.

What it saves is bigger than that, and it sits earlier: the design and documentation phase, the pre-application back-and-forth, the consultant fees, and the risk of a refusal or a re-lodgement. That is the part of an ACT infill project that actually consumes years, and it is the part you control — which is precisely why it is worth paying someone else to have solved it already.

What it does to the numbers

• Removes DA fees and most planning consultant costs.
• Removes the design and documentation phase — the genuine long pole — along with the assessment period itself.
• Cuts finance cost proportionally, because holding cost is months × drawn balance × rate.
• Removes refusal risk. Around 5% of lease variation applications are refused outright and more are withdrawn; a refusal after eighteen months of design is the most expensive outcome available.
• Makes the remission deadline comfortable. The missing middle remission requires approval before 30 June 2029 and completion by 31 December 2030.

The trade

You build what the pattern book designed. If the block is unusual — steep, battleaxe, narrow frontage, heritage-adjacent — a standard design may not suit it, and the saving evaporates if you end up needing a bespoke scheme anyway.

Check design suitability before assuming the shortened programme. But on a regular block in RZ1 or RZ2, this is the most valuable thousand dollars available in ACT development.
