Original stone farmhouses here use rubble-stone bearing walls between 750 and 1100 mm thick on shallow stone footings; structural modifications require a heritage-experienced engineer and an MCC-approved heritage architect.
Landscape elements (stone walls, rangs, mature sugar-maple alleys) are individually inventoried under the heritage designation — removal or modification of these features is generally refused unless restoration justification is documented.

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.
