Knockdown Rebuild in ACT: A Practical Step-by-Step Guide

A clear, builder’s-eye view of the approvals, costs, timeframes, and common surprises in ACT knockdown rebuilds.

Knockdown rebuild (KDR) is one of the best ways to get a brand-new home in an established suburb — but only if you understand the process early.

Step 1: Feasibility (before you spend big)

  • Confirm planning controls and what can be built on your block
  • Check demolition constraints (asbestos, access, trees)
  • Rough budget for site costs (demolition, services, earthworks)

Step 2: Design + documentation

In ACT, documentation quality matters. Better documentation = fewer variations later.

Step 3: Approvals + certifier pathway

Your timeframe can vary depending on documentation and authority response times.

Step 4: Demolition + service disconnections

Book these early. Delays often happen here.

Step 5: Build (site costs are where budgets move)

Rock, slope, drainage, retaining, temporary works — this is why we plan site costs carefully.

Step 6: Handover

Aim for a practical handover: defects list, compliance docs, warranties, and maintenance guide.
