Melbourne decks and pergolas typically need a Building Permit; Planning Permit required where setbacks, height, or Heritage Overlay trigger assessment. ResCode Clause 55 standards apply to structures visible from the street or affecting neighbour amenity. Peri-urban lots in bushfire zones require BAL-rated timber or compliant alternatives under AS 3959.

Hardwood decking — merbau, spotted gum, blackbutt, ironbark — remains traditional. Composite decking gains share, BAL-rated options available for bushfire overlay lots.

AskBaily routes your Melbourne deck and pergola to a VBA-registered builder with structural engineering and planning paperwork.

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.
