Custom home design in Belleville
Belleville is 19e + 20e arr.'s pre-haussmann village + late-19th c. faubourg + 20th c. social submarket. Belleville was annexed to Paris in 1860 along with Montmartre — its hilltop village preserved pre-1860 lot lines and shared courts that survive in current cadastre, so any extension scope first surfaces 1850s-vintage servitudes that may not appear on standard PLU maps.
What a custom home design project looks like here
Belleville was annexed to Paris in 1860 along with Montmartre — its hilltop village preserved pre-1860 lot lines and shared courts that survive in current cadastre, so any extension scope first surfaces 1850s-vintage servitudes that may not appear on standard PLU maps.
The Belleville carrière (gypse) extends from the Buttes-Chaumont down through the arrondissement — IGC reports here are particularly likely to find unmapped voids requiring micropieux foundation systems.
Ground-up residential within Greater Paris — design through Permis de Construire through réception des travaux. PLU + PSMV compliance, Architecte DPLG signature mandatory above 150 m² SHON. In Belleville specifically, pre-haussmann village + late-19th c. faubourg + 20th c. social stock means custom home design 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.
Questions LA homeowners actually ask
Belleville custom home design projects typically run $685K–$3.9M. Belleville's pre-haussmann village + late-19th c. faubourg + 20th c. social stock, combined with pre-1860 belleville village fabric — pre-haussmann lot lines, puts most mid-complexity projects in the $2.3M range. Baily scopes the exact band once you describe the work.
