New home construction in Allston
Allston is Boston's triple-decker wood-frame multifamily (1890-1920) submarket. Allston's triple-decker stock concentrates between Commonwealth Avenue and Soldiers Field Road — roughly 1,200 triple-decker buildings, the densest concentration in Boston after Dorchester — and the 1900-1920 framing convention here uses 2x8 floor joists at 16-inch spacing across a 22-foot span, lighter than the South Boston standard.

Because Allston has hosted Harvard graduate housing demand since the 1970s, many triple-decker units have been re-partitioned into 4-bedroom configurations that violate original CSL filing — kitchen renovations frequently surface unpermitted bedroom conversions that must be reconciled with ISD before the new permit clears.
The Allston-Brighton Strategic Planning area governs Harvard's institutional expansion under the BPDA's Article 80 process — adjacent residential parcels carry restrictive scope on rear-yard additions because of the 50-year planning horizon for the Harvard land bank.
From empty lot through Certificate of Occupancy — zoning-compliant, permit-aware, inspection-scheduled under Boston ISD or suburban Building Department oversight. In Allston specifically, triple-decker wood-frame multifamily (1890-1920) stock means new home construction scope is shaped by the neighborhood's dominant construction typology. Baily's Boston scoping flow factors mgl ch. 111 §197a delead on triple-decker stock (~92% pre-1978) and boston allston-brighton strategic plan governs density on harvard expansion into the estimate before a contractor is involved.

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.
