Sydney’s Federation, Victorian and Californian bungalow homes are full of character: decorative timberwork, high ceilings, leadlight windows and verandahs. Renovating one well means keeping what makes it special while making it comfortable for modern life. It also means following heritage rules that don’t apply to most houses.
Is your home heritage-listed or in a conservation area?
There are two main types of heritage control in NSW:
- Heritage item: the property itself is listed in the council’s Local Environmental Plan (LEP) or on the State Heritage Register.
- Heritage conservation area (HCA): the property sits in an area protected for its overall character, even if the house isn’t individually listed.
Check your property on the NSW Planning Portal’s spatial viewer or with your council’s duty planner before you design anything. Many homes in the Inner West, Eastern Suburbs and North Shore fall into one category or the other.
What approvals do heritage renovations need?
- Minor works and maintenance: many councils allow minor works, like repainting traditionally painted surfaces, repointing in traditional mortar or repairing timber windows, without full consent. You must get the council’s written confirmation first, often called a heritage exemption.
- Development Application (DA): most alterations and additions to heritage items need a DA, usually with a Heritage Impact Statement.
- Complying Development Certificate (CDC): available for some works in conservation areas when they meet the state standards, but generally not for heritage items.
- State Heritage Register items may also need approval under the Heritage Act 1977, even for minor works.
Rules vary between councils, so confirm your pathway early (Woollahra Council, Inner West Council). Work done without the right approval can’t be approved after the event.
Restoring original timberwork
Heritage homes rely on carpentry details that standard products don’t match: verandah posts and fretwork, skirtings and architraves, panelled doors, double-hung sash windows and timber floors. Good heritage carpentry means:
- Repairing before replacing. Splicing in new timber keeps more original fabric and is usually what council expects.
- Matching profiles. New mouldings, skirtings and architraves are made to match existing profiles.
- Using suitable species and traditional joints, so new work ages the same way as the old.
- Fixing the cause of decay, such as rising damp, poor drainage or termites, before repairing the timber. See our guide to rising damp solutions.
Modernising without losing character
- Keep the street front, change the back. Councils usually accept a contemporary rear addition when the original front rooms and streetscape are kept.
- Make new work distinguishable but sympathetic in scale, materials and roof form.
- Upgrade comfort quietly: ceiling and underfloor insulation, draught sealing and secondary glazing improve comfort without changing the facade.
- Hide modern services in new work rather than chasing them through decorative plaster and joinery.
- Reuse salvaged materials such as floorboards, bricks and doors in the new work where you can.
Common heritage renovation mistakes
- Starting work before checking the heritage status
- Replacing original windows and doors that could have been repaired
- Painting face brick or sandstone
- Using cement mortar on soft heritage brickwork
- Treating damp with surface sealers instead of fixing the cause
- An addition that overpowers the original house

Frequently asked questions
How do I know if my house is heritage-listed?
Check your council’s LEP heritage schedule or the NSW Planning Portal, or ask the council’s duty planner.
Can I renovate a heritage-listed home?
Yes. Most alterations need a DA with a Heritage Impact Statement, and minor works may be allowed with the council’s written confirmation.
Can I extend a house in a heritage conservation area?
Usually yes. Rear additions that keep the original front and streetscape are the most commonly approved.
Should I replace or repair original timber windows?
Repair where you can. It keeps the character, and councils generally expect it.
