Custom home design in 8e Arrondissement (Champs-Élysées / Étoile)
8e Arrondissement (Champs-Élysées / Étoile) is 8e arr. — Élysée's haussmannien grand standing (1853-1870) submarket. The 8e was the prototype Haussmann arrondissement — 84% of the building stock dates to 1853-1870 and the cornice height, mansard pitch, and stone-balcony spec are all locked at their original 1859 PLU equivalents through the SPR Champs-Élysées, so balcony glazing and rooftop additions have a near-zero approval rate.

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.
