A Sydney laundry renovation sounds simple until you touch the drainage. Every laundry discharges to the sanitary sewer under Sydney Water's trade-waste regime and any alteration to the drain line, gully trap, or floor waste requires a licensed plumber and a Certificate of Compliance. A laundry within a strata apartment typically sits directly above or below a neighbour's wet area, so waterproofing under AS 3740-2021 and acoustic isolation become Owners Corporation issues, not just lot-owner preferences.

"European laundries" tucked into a cupboard are popular in inner-city apartments but trigger the same waterproofing, ventilation, and electrical requirements as a standalone laundry — plus mechanical exhaust at 40 L/s minimum under NCC F6.

AskBaily routes your Sydney laundry renovation to a NSW-licensed builder who coordinates plumbing compliance, strata by-law amendments, and asbestos removal on pre-1990 laundries.

What a Sydney laundry renovation involves

  • Plumbing. Licensed plumber for tub, tap, washing-machine connection, and floor-waste alterations. Sydney Water Certificate of Compliance on completion.
  • Electrical. Licensed electrician for dedicated circuits, washing-machine outlet, dryer outlet. RCD protection mandatory.
  • Waterproofing. AS 3740-2021 compliance on floor, hobs, and walls to 150 mm above floor level (full wall to 1800 mm if behind a shower).
  • Strata. SSMA 2015 consent where common property is affected. Acoustic separation to the slab above and below.
  • BASIX. Water-fixture WELS ratings. Hot water system efficiency.

Frequently asked questions

Do I need council approval for a Sydney laundry renovation? Usually no — internal like-for-like refit is exempt. Any structural alteration, external wall change, or fire-rating impact triggers CDC or DA.

Can I install a European laundry in a bedroom cupboard? Only with proper ventilation (mechanical exhaust at 40 L/s), AS 3740 waterproofing, dedicated electrical circuits, and strata consent. Some older strata schemes block laundry conversions outright via by-law.

How much does a Sydney laundry renovation cost? A$14,000-A$22,000 for a standard laundry refit. A$24,000-A$28,000 for a European laundry conversion with ventilation, waterproofing, and custom joinery. Budget 3-5 weeks.

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.
