Renovating a Period Home in Melbourne's Inner East: What to Know Before You Start

The heritage overlay: what it actually restricts

A heritage overlay doesn't mean you can't renovate — it means changes visible from the street (and in some heritage precincts, some internal changes) need a planning permit on top of the standard building permit. In practice, this usually affects:

• Front facades, rooflines and street-facing additions
• Removal of original features (verandahs, chimneys, decorative brickwork)
• Materials and colours used on visible exterior surfaces
• Second-storey additions, which are scrutinised more closely for visual impact from the street

Rear extensions and internal renovations are generally more flexible, since they're less visible and less likely to affect the property's heritage character.

What's different about renovating a period home

• Original services are often original. Wiring, plumbing and sometimes even structural elements in homes from this era haven't always been updated since construction. Budget a contingency (10–15% is a reasonable starting point) for what's found once walls or floors are opened up.
• Asbestos is common in pre-1990s homes. Sheeting, tiles and old flooring materials may contain it. Testing and safe removal, if needed, typically adds $3,000–$15,000 and should be budgeted for rather than treated as a surprise.
• Narrow blocks change what's practical. Many Hawthorn and Camberwell blocks are narrower than newer-estate equivalents, which affects extension footprint, site access for trades and equipment, and sometimes cost.
• Character matters to resale value. Renovations that respect the home's original style — rather than stripping period features for a generic modern look — tend to perform better both with heritage assessors and at resale.

A real project: Hawthorn ensuite renovation

A tired 1990s ensuite in a period Hawthorn home was reworked into a master retreat: plumbing relocated for a freestanding bath, a frameless walk-in shower with a stone niche, and a custom double vanity with integrated lighting — full strip-out, certified waterproofing, new ventilation and finishes, delivered for $58,400 fixed-price in 6 weeks on-site. The heritage overlay on this property didn't affect the ensuite itself (an internal, non-structural space), but it did factor into the initial site assessment.

How to start a period home renovation the right way

1. Check your property's overlay status first, before finalising any design — this determines whether you need a planning permit and how much flexibility you have with exterior changes.
2. Get a site assessment that accounts for the building's age — old wiring, plumbing, and potential asbestos should be flagged before you're quoted, not discovered mid-build.
3. Design with the existing character in mind, especially for anything visible from the street.
4. Build in extra time for planning permit assessment if your changes affect the exterior — this can add 4–12+ weeks versus a building-permit-only project.
