The 1920s HBM cohort along rue Manin and rue Botzaris has a uniform brick + RC frame structural language — restoration specs developed for one block transfer to others, but cooperative AG voting can stretch any parties communes intervention to 18-24 months.
Feasibility, programme, planning-pathway validation before commitment — Mairie de Paris urbanism officer pre-app, ABF early consultation, PSMV screening. In Buttes-Chaumont specifically, late-19th c. + 1920s hbm cohort + park-edge villas stock means pre-construction design-build scope is shaped by the neighborhood's dominant construction typology.

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.
