Sydney's heritage regime sits on three tiers. The State Heritage Register (SHR) under the Heritage Act 1977 covers properties of state significance — approvals go through the Heritage Council of NSW and typically require a Heritage Impact Statement and a specific conservation management plan. LEP Schedule 5 lists locally significant heritage items in each council's Local Environmental Plan — approvals go through council with a Heritage Impact Statement and heritage adviser review. Heritage Conservation Areas (HCAs) under the LEP cover whole streetscapes in inner-Sydney — Paddington, Surry Hills, Darlinghurst, Glebe, Balmain, Woollahra, Hunters Hill, parts of Mosman and North Sydney — with controls on exterior alterations, demolition, and new development that must respect the streetscape character.

Unauthorised work on a SHR property is a Heritage Act offence carrying fines into six figures. Unauthorised work on an LEP-listed item or HCA property is a council compliance issue leading to stop-work orders and retrospective DA applications.

AskBaily routes your Sydney heritage renovation to a NSW-licensed builder with heritage trade references, a heritage consultant on retainer, and documented DA-approval history with your council's heritage team.

What a Sydney heritage renovation involves

  • Tier identification. SHR (Heritage Council NSW), LEP Schedule 5 (council), HCA (council). Check the Section 10.7 certificate.
  • Heritage Impact Statement. Prepared by a heritage consultant. Describes significance, impact of proposal, mitigation. Council heritage adviser review.
  • Materials. Traditional materials matched to period — sandstone, brick, slate roof, timber weatherboard, cedar joinery. Modern replacements subject to heritage approval.
  • Tradespeople. Specialist heritage trades — sandstone masons, slaters, lime plasterers, traditional joinery fabricators.
  • Timeline. 16-30 weeks consent + 9-18 months build on a full heritage renovation.

Frequently asked questions

What is a Heritage Impact Statement? A HIS describes the heritage significance of the place, the proposed works, their impact on significance, and proposed mitigation. Prepared by a qualified heritage consultant. Mandatory for any DA affecting an SHR, LEP schedule 5, or HCA property.

Can I demolish a heritage-listed building? SHR properties — effectively no without extraordinary justification and Heritage Council approval. LEP schedule 5 — requires specific council DA with strong justification. HCA properties — demolition of contributory buildings is typically refused.

How much does a Sydney heritage renovation cost? A$380,000-A$680,000 for a mid-spec heritage-compliant terrace renovation. A$720,000-A$1.2M for a full heritage renovation with significant interior works. A$1.5M-A$1.8M+ for state-listed harbourside heritage renovations with specialist trades.

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
