Project approach

How we structure the work.

Every granny flat project is different, but the same principle applies: better decisions early produce a cleaner approval process and a better finished outcome.

Step 01
Site assessment and feasibility

We review your lot size, zoning, overlays and existing coverage before recommending a design approach — avoiding surprises that cost time and money later.

Step 02
Design, documentation and approval

We prepare the plans and manage council submissions, selecting the fastest compliant pathway for your site whether that is CDC or DA.

Step 03
Construction and handover

Trades are coordinated from slab to fit-out. You receive a completed, compliant dwelling ready for occupation — managed by the same team throughout.
