Rear & side extensions in Bethnal Green
Bethnal Green is London Borough of Tower Hamlets's georgian weavers' houses (1720-1770) + victorian terraces + post-war lcc council estates (lansbury) submarket. Fournier Street and surrounding weavers' streets have among the highest density of Grade II* listings in London — many have original 1720s floorboards, staircases, and panelling, so even moving a skirting requires LBC and a conservation carpenter on site.
What a rear & side extensions project looks like here
Fournier Street and surrounding weavers' streets have among the highest density of Grade II* listings in London — many have original 1720s floorboards, staircases, and panelling, so even moving a skirting requires LBC and a conservation carpenter on site.
The Lansbury Estate was built in 1951 as a Festival of Britain Live Architecture exhibit and is Grade II listed — alterations within flats require LBC, and Tower Hamlets applies this strictly even for tenanted council properties.
Tower Hamlets' 2021 Article 4 Direction restricts HMO (House in Multiple Occupation) permitted-development conversions across Bethnal Green, so a 4-bed-to-5-room conversion now requires a full planning application tested against HMO standards.

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.
