What a rear & side extensions project looks like here
Camberwell Grove has an intact run of 1770s-1810s Georgian terraces — all Grade II listed — where original mahogany staircases and window shutters must be retained; LBC is required for internal paint colour changes as well as structural work.
Southwark's Basement Policy DPD 14 is strict on multi-storey subterranean excavation — effectively limiting Camberwell basements to single storey below principal elevation with a formal Basement Impact Assessment required even for single-storey dig.
Because Camberwell's pre-1870 terrace stock often has original shallow footings at 900mm, underpinning is a routine scope addition on basement conversions — typical adder £22,000-£35,000 on a terrace conversion.
Rear extensions, side-return infills, wraparound extensions — Permitted Development Class A rights or planning consent under the Article 4 borough overlay; Party Wall etc. Act 1996 notice on any party-wall touch. In Camberwell specifically, georgian + early-victorian terraces (1820-1870) + post-war lcc estates stock means rear & side extensions 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.
