Energy renovation in Saint-Germain-des-Prés
Saint-Germain-des-Prés is 6e arr.'s 17-18th c. faubourg + 19th c. haussmannien infill submarket. Saint-Germain-des-Prés Abbey (founded 558 CE, current church 990-1014 CE) is one of Paris's oldest Monuments Historiques classés — its 500 m perimeter makes ABF avis conforme binding, and the typical pre-1789 stone-vaulted basements in the surrounding faubourg make any deep utility re-routing structurally non-trivial.

Many hôtel particulier conversions to multi-unit co-propriétés in the late 19th century preserved the original noble-floor layout (étage noble) — current PLU + ABF often forbids further internal subdivision because the étage noble plan itself is treated as patrimoine.

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.
