General building in 1er Arrondissement (Louvre)
1er Arrondissement (Louvre) is 1er arr. — Louvre's haussmannien (1853-1870) submarket. The 1er arrondissement contains the densest Monument Historique perimeter in France — every parcel sits within 500 m of at least three classés monuments, which means the ABF avis is conforme (binding) rather than simple, and façade colour matches alone routinely take 8-14 weeks to clear.
What a general building project looks like here
The 1er arrondissement contains the densest Monument Historique perimeter in France — every parcel sits within 500 m of at least three classés monuments, which means the ABF avis is conforme (binding) rather than simple, and façade colour matches alone routinely take 8-14 weeks to clear.
Most pre-Haussmann Louvre quarter buildings have shared lightwell shafts (cours intérieures) — any kitchen extraction stack relocation requires unanimous co-propriété AG vote per Article 26 because the shaft passes through multiple lots, not just yours.

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.
