Commercial construction in Rosemont
Rosemont is Rosemont–La Petite-Patrie's 1920s-1940s greystone + brick triplex stock; some post-war single-family; large tree-lined working-class east-end neighbourhood submarket. Rosemont has one of Montréal's largest stocks of intact 1920s-1940s greystone triplex housing, and the arrondissement's PIIA review extends character protection to most pre-1940 plex facades — exterior staircase replacement, cornice restoration, and visible window alteration all trigger borough design review.
What a commercial construction project looks like here
Rosemont has one of Montréal's largest stocks of intact 1920s-1940s greystone triplex housing, and the arrondissement's PIIA review extends character protection to most pre-1940 plex facades — exterior staircase replacement, cornice restoration, and visible window alteration all trigger borough design review.
Rosemont's plex stock typically has shared rear-yard access via narrow lanes, and many renovation projects require coordinating with the city's lane-paving maintenance schedule — a renovation that requires lane closure for material delivery frequently needs city Public Works coordination, adding 2-6 weeks to scheduling.

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.
