Granny flat builders in Armadale
An information-only vetting guide for granny flat builders working on Armadale period homes. A Armadale granny flat can be either a Dependent Persons Unit (DPU, dependent-relative only, temporary) or a Secondary Dwelling (2023 planning reform, permanent, lettable). Both are capped at 60m² and both need Planning Permit approval in most cases. In Armadale's established-suburb lots, service split and Heritage Overlay implications shape the design more than the class distinction. BuildPilot is not yet matching builders in Armadale - this is a curator's checklist while VIC matching rolls out in 2026.

What matters in Armadale
Armadale architectural era
Predominantly Victorian terrace, Edwardian bay-window and Federation stock. Some inter-war blocks and post-1990s infill. High density of period detail; grand High Street mansions.
Heritage + planning overlays
Approximately 55-65% under Heritage Overlay - one of the more heavily heritage-controlled Stonnington suburbs. Tree Protection Local Law covers larger canopies. Stonnington planning permit lead time (heritage): 4-9 months for internal + external, 8-14 months for extensions with visible changes.
Typical lot geometry
Median residential lot 400-550m². Larger 700-900m² lots along Kooyong Road / Malvern Road. Terrace stock 5-7m frontage in central Armadale.
DPU vs Secondary Dwelling classification
DPU is dependent-relative only and cannot be rented commercially - it must be removed or converted when the relative moves out. Secondary Dwelling under 2023 reforms is permanent and can be rented on the open market. Which route suits Armadale depends on Stonnington City Council's local policy and whether the primary dwelling remains the principal residence. Get the classification confirmed in a pre-application meeting before drawings.
Armadale FAQs
Can I rent out a granny flat in Armadale?
Only if classified as a Secondary Dwelling under 2023 planning reforms. A DPU is dependent-relative only. Both share the same title as the main dwelling. Full subdivision (separate title) is a separate Planning process, typically under Clause 55 dual occupancy, and much slower.
Do I need a Planning Permit for this work in Armadale?
Approximately 55-65% under Heritage Overlay - one of the more heavily heritage-controlled Stonnington suburbs That means most external work (extensions, window relocations, front-elevation changes, roof-form changes) triggers a Planning Permit before Building Permit. Internal-only work often only needs a Building Permit. Check Stonnington City Council's heritage assessment guidance or a title search on VicPlan (mapshare.vic.gov.au) before you commission drawings.
How do I verify a granny flat builder operating in Armadale?
Three checks: VBA public practitioner register at vba.vic.gov.au/practitioners/register (ARBV register at arbv.vic.gov.au for architects); Domestic Building Insurance (DBI) eligibility confirmation with VMIA for your contract price - compulsory over $16,000; Three completed Stonnington City Council projects delivered in the last 24 months, with the client's permission to inspect. Do all three before you pay any deposit.
Why do Armadale trades cost more than the Melbourne median?
25-45% above Melbourne median trade rates. Contributing factors: heritage-detail skill premium, tighter site access on established streets, specialist trade selection (heritage plaster, cast iron, leadlight, sympathetic joinery), and premium finish-level expectation on Armadale projects. Trade rates in Armadale track closer to inner-Melbourne premium rates than to greenfield growth-corridor rates.
