Home extension builders in Brighton
An information-only vetting guide for home extension builders working on Brighton period homes. A Brighton home extension - rear ground-floor, side-return infill, or first-floor addition - integrates a contemporary volume with an existing period home. The heritage overlay controls what happens above the ridgeline; ResCode Clause 54 controls overshadowing and overlooking on the neighbour boundary. BuildPilot is not yet matching builders in Brighton - this is a curator's checklist while VIC matching rolls out in 2026.

What matters in Brighton
Brighton architectural era
Predominantly Victorian, Edwardian and inter-war brick homes plus mid-century modernist Brighton East. Beachfront strips include 1980s-2010s luxury rebuilds.
Heritage + planning overlays
Roughly 55% of Brighton and Brighton East sit under a Heritage Overlay. Coastal salt-air building requirements apply within 4km of Port Phillip Bay. Vegetation Protection Overlay on many streets. Bayside planning permit lead time (heritage): 3-6 months for straightforward renovations, 8-12 months for extensions or first-floor additions.
Typical lot geometry
Median residential lot 600-900m². Beachfront lots exceed 1,200m². Narrower 8-12m frontage 1930s Cal-bung streets.
Heritage-visible ridgelines and first-floor setbacks
Bayside City Council heritage assessment typically requires that any first-floor addition sit behind the original ridgeline, set back from the front elevation, and finished in a sympathetic (but distinguishable) material palette. A rear extension is usually approvable; a visible first-floor addition can fail heritage. Concept-stage feedback from the council heritage officer saves 3-6 months.
Brighton FAQs
How much does a home extension cost in Brighton?
Rear ground-floor extension (30-60m²): $280k-$550k. First-floor addition (60-100m²): $450k-$950k. Full renovation with rear extension and first-floor: $850k-$2.5m+. Costs sit 20-35% above Melbourne median because of the heritage detail requirement, tighter site access, and specialist trade selection.
Do I need a Planning Permit for this work in Brighton?
Roughly 55% of Brighton and Brighton East sit under a Heritage Overlay 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 Bayside 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 home extension builder operating in Brighton?
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 Bayside 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 Brighton trades cost more than the Melbourne median?
20-40% above Melbourne median trade rates because of premium finish expectation, marine-grade material spec, and Bayside's premium trade network. 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 Brighton projects. Trade rates in Brighton track closer to inner-Melbourne premium rates than to greenfield growth-corridor rates.
