Pre-construction design-build in Balmain
Balmain is Inner West Council's federation and inter-war workers' cottages submarket. Balmain's harbour-frontage lots are subject to a Foreshore Building Line under Inner West LEP 2022 — most rear extensions on Darling Street-side lots need a clause-5.10 heritage-impact statement and clause-6.1 foreshore-protection assessment.

Many Balmain workers' cottages have hand-cut Sydney sandstone foundations — any underpinning or footing work requires a structural engineer's letter that confirms compatibility with the existing rubble-and-mortar mass, which most modern engineers will only sign after a destructive sampling test.
The Inner West DCP caps two-storey rear additions on heritage cottages at 4.5m above natural ground level on the rear elevation — a common scope-killer that drives most projects into a single-storey wraparound with skylight rather than a full second floor.
Feasibility, programme, DA-pathway validation before commitment — pre-DA council meeting, HCA + Tree Preservation Order screening, BASIX modelling. In Balmain specifically, federation and inter-war workers' cottages stock means pre-construction design-build scope is shaped by the neighborhood's dominant construction typology.

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.
Questions LA homeowners actually ask
Balmain pre-construction design-build projects typically run $10K–$75K. Balmain's federation and inter-war workers' cottages stock, combined with balmain heritage conservation area — inner west lep 2022, puts most mid-complexity projects in the $42K range. Baily scopes the exact band once you describe the work.
