Pool & spa construction in Saint-Michel
Saint-Michel is 5e + 6e arr.'s medieval fragments + 17-19th c. faubourg submarket. The Saint-Michel quartier sits inside the densest cluster of pre-1700 medieval fragments in Paris — façade restoration routinely surfaces lath-and-plaster or pierre de taille of unknown provenance that triggers Service Régional de l'Archéologie diagnostic before exterior work proceeds.
What a pool & spa construction project looks like here
The Saint-Michel quartier sits inside the densest cluster of pre-1700 medieval fragments in Paris — façade restoration routinely surfaces lath-and-plaster or pierre de taille of unknown provenance that triggers Service Régional de l'Archéologie diagnostic before exterior work proceeds.
Many Saint-Michel buildings have shared 12th-13th century well shafts visible from the cellar — these are protected as patrimoine archéologique and any below-grade utility work must route around them.

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

Saint-Michel's medieval fragments + 17-19th c. faubourg stock, combined with abf avis conforme — notre-dame + sainte-chapelle + sorbonne perimeters, puts most mid-complexity projects in the $425K range.
