Melbourne apartment renovations succeed or fail on the Owners Corporation, not the builder. Under the Owners Corporations Act 2006, any work affecting common property — waterproofing, acoustic layer, facade, services riser, balcony balustrade — requires Owners Corporation resolution. Some changes require a special resolution at a general meeting. A risk-averse or hostile OC can block a renovation for 6-12 months.

Acoustic isolation under NCC Section F5 (airborne + impact sound between dwellings) is a frequent compliance pressure point on floor reconstructions. Common-property waterproofing sits on the lot boundary; building-manager coordination and lift booking add further coordination overhead.

AskBaily routes your Melbourne apartment renovation to a VBA-registered builder who carries OCA consent references, acoustic consultant relationships, and building-manager negotiation experience.

Frequently asked questions

What OC consent do I need? OCA 2006 resolution for work on common property. Special resolution at a general meeting for significant alterations. Some schemes operate standing rules allowing minor renovation work with committee approval only.

Can my OC block my renovation? Yes, within reason. An owner may apply to the Victorian Civil and Administrative Tribunal (VCAT) if consent is withheld unreasonably.

How much does a Melbourne apartment renovation cost? A$80,000-A$120,000 for a mid-spec 2-bedroom apartment refresh. A$130,000-A$200,000 for a high-spec renovation with full kitchen, bathroom, flooring. A$250,000-A$600,000 for prime-east apartments with structural alterations and imported fixtures.

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.
