The 5e contains some of the oldest residential cellars in Paris — many rue Mouffetard buildings have 13th-14th century cave foundations that show up on the cadastre as patrimoine archéologique, and any deep excavation triggers a Service Régional de l'Archéologie diagnostic before earthwork begins.
Because the quarter sits on the geological Bièvre alluvium, sub-grade groundwater is shallow — most basement-conversion projects require permanent dewatering pumps and a SAGE / hydrogeology declaration that adds 6-10 weeks to the dossier.

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.
